Page 37: Purge Air Alarm
Purge Air Alarm The analyzer contains circuits that detect the loss of purge air to the analyzer and generate alarm signals to the operator. The customer has the responsibility to connect the purge alarm to a visual or audible annunciator located in a constantly monitored area, as required by NFPA 496 (1993). Liquid Sample Valve The Liquid Sample Valve (LSV) utilizes two different connection methods for the sample lines.
Page 38: Equipment Mounting
New analyzers have the sample lines connected to a mounting plate attached to the LSV's mounting flange, as shown in Figure 2-2. Customer Connections Figure 2-2. LSV CONNECTION METHODS, NEW ANALYZERS You must take extreme care to avoid having the sample lines exert force on the sample connections of the Liquid Sample Valve.
Page 39: Analyzer Air
1. Do not remove the tube caps, provided at the analyzer tubing ports to prevent deterioration of the columns, until immediately before making each connection. 2. Use an anticorrosion material for the lines and fittings. 3. To ensure using proper size tubing and pipe, refer to the Outline and Mounting Dimensions Diagram contained in the Data Package.
Page 40: Electrical
The manifold vent must be plumbed from the analyzer to a safe area at 0 psia or atmospheric vent. To do this, connect appropriate tubing to the manifold vent (see Figure 2-3) and run this tubing to a hazard-free area. MANIFOLD VENT Figure 2-3.

Page 82: Technical Description
SECTION 4. TECHNICAL DESCRIPTION FUNCTIONAL DESCRIPTION Figure 4-1 shows a typical analytical flow system, using the flame ionization detector for illustration. Connections at the right side of the analyzer cabinet provide all gas and air inputs. Sliding plate valves, liquid sample valves, or a combination of both, provide control and measurement of the sample.
Page 83: Detectors
The carrier gas has three purposes: to purge the columns and cell prior to introducing a sample, to sweep the sample into the detector cell, and to backflush the backflush column. An externally mounted pressure regulator and gauge regulate the input flow. The sample system, together with the GCC, controls the calibration sample input.

Page 85: Thermal Conductivity Detector (Tcd)
The cell consists of a polarized jet, a collector, and a chamber in which hydrogen fuel and sample are burned in air. A current, whose magnitude is proportional to the concentration of the sample, flows between the jet and the collector. This current goes to the FID Amplifier Assembly. The FID Amplifier Assembly provides ignition control for the FID cell and amplification of the detector cell output signal prior to routing the signal to the control section for signal processing.
Page 86: Flame Photometric Detector (Fpd)
Flame Photometric Detector (FPD) Flame photometric detection works on the principle that when sulfur is burned in a hydrogen-rich atmosphere, luminescence (light) characteristic to sulfur is produced. The FPD cell (see Figure 4-5) consists of a teflon burner chamber equipped with a spark ignition system, and a photomultiplier tube which is thermoelectrically temperature controlled.
Page 87: Simultaneous Dual Detectors
Simultaneous Dual Detectors Simultaneous dual detectors function in parallel using any two detectors. To accomplish this simultaneous processing requires one Chroma I/O Board in the analyzer for each detector. Chroma I/O Board #1 is in GCC Card Cage slot 2 and Chroma I/O Board #2 is in slot 1. Stream assignments and method tables determine which detector processes each stream and method.

• Vista Basic commands identify the detector by placing the Chroma I/O Board number after the alarm name (e.g., CUR_STRM (1) or INTEGER = RAI (1,0), where the first digit identifies the Chroma I/O Board). Before starting an analysis, the GCC prompts for the Chroma I/O Board to use during the analysis. The selected Chroma I/O Board must be in Master mode or the analysis will not start.
Page 93: Tcd Amplifier Pcb
TCD Amplifier PCB The TCD Amplifier PCB, on the left side wall of the GCC, amplifies the thermal conductivity detector output signal and provides it to the Chroma I/O Board for processing. FPD Amplifier and Interface PCBs The FPD Amplifier PCB linearizes and amplifies the flame photometric detector output signal and applies it to the Chroma I/O Board for processing.
Page 94: Communications Pcb (Option)
Communications PCB (Option) The Communications PCB, in any open slot in the GCC Card Cage, provides a two-channel interface between the GCC and the VistaNET. This PCB is not used when the analyzer has the optional Ethernet PCB. See "VISTANET OPTION" for a detailed explanation of the VistaNET option. VistaNET Interconnect PCB (Option) The VistaNET Interconnect PCB, located on the side of the GCC Card Cage, provides low-speed interface between the GCC and the VistaNET.

between the various components is established (at installation), only the K-factor is changed during calibration. Preparing a Method Table This subsection explains how to prepare a method table by constructing a sample method table. Figure 4-12 shows a chromatogram of the analysis to be controlled. This analysis is 90 seconds long and has three components to measure: A, B, and C.

method has forced gating and slope detection on at the same time, the controller uses the one turned on first, ignoring the second one and sending an alarm to tell you that both peak detection methods were on. Forced Gating When a component's elution time is known, forced gating can measure the peak.
Page 103: Slope Detection: Supplemental Functions
higher number causes the system to respond less quickly but is more sensitive. For that reason the default is set at 8, a median value that provides both good response and sensitivity for most applications. Peak width only has meaning when slope detect is running. Slope Detect On tells the method that slope detection will be used for this analysis.
Page 104: Example Of Tangent Skim
peak which begins on a valley point (see Figure 4-22). Since the tangent skim termination search operates only during a single peak, it is activated by setting Tangent Skim at the proper time in the method table (no On/Off is required). To use tangent skim, choose a time in the method table that occurs at a point before the peak in question and set Tangent Skim.

different peak areas in adjacent analyses (see Figure 4-23). By selecting “Pk End =Vly” you can force the routine to call it a valley each time it occurs, thus removing the indecision and stabilizing the calculations. “Pk End =Base” is used the same way as “Pk End =Vly.” Selecting “Pk End =Vly” or “Pk End=Base”...
Page 106: Example Of Reverse Projection
“Proj Reverse” is a reverse projection flag that identifies the end of a desired peak or group of peaks. It is set in the baseline after the end of the peak (see “HBR” in Figure 4-25). With reverse projection, “Proj Term” is set before the start of the peak—and before “Proj Reverse” (see “HBT” in Figure 4-25). The system then measures the peak that occurs between HBT and HBR.
Page 107: Other Time-Coded Functions
Another method for handling badly tailing peaks is “End=Crest+” (see Figure 4-27). This code forces the end of the peak to be the crest time plus the time specified in the code, providing a reproducible end to the peak even if the crest of the peak is moving. To use this command, insert “End = Crest+” into the method together with a specified time after the crest.
Page 108: Stream Step
NOTE If any of the above conditions exist, an error will occur. Stream Step Stream Step begins the automatic sample purge of the sample stream being analyzed. It must occur after completion of the sample inject for this stream. This is particularly important when the current stream being analyzed requires multiple sample injections.
Page 109: Skip Next Tcf If Stream
Skip Next TCF If Stream = This allows you to skip the next time-coded function when this stream value equals the stream number entered in the method table. This function allows you to skip a TCF on a particular stream, usually because that TCF does not apply to that stream.

Page 116: Purge Operation
will reduce the classification to Nonhazardous/General Purpose. Since the Y and Z Purge systems are identical except for nomenclature, the following explanation applies to both. The purge air enters the analyzer system through a pressure regulator, an orifice, and a gauge used to set purge flow, and then into the electronics housing where purge air flow is maintained until a fault condition exists.
Page 117: Purge Override Option
The X Purge cycle time depends totally on the application, but it may vary with analyzer configuration and condition. Refer to the analyzer label or Data Package for specific purge specifications. Once X Purge applies power to the analyzer, power continues to the analyzer as long as the electronics housing maintains air purge pressure.
Page 118: Purge Override Contacts
6. With X Purge reset, the air purge timed cycle begins in the electronics housing. When you use Override during start-up, it overrides the X Purge control of power to the analyzer, but the air purge timed cycle continues. Once the electronics housing has pressurized and X Purge completes its timed purge cycle, the analyzer will have power from the X Purge.

SECTION 6. TROUBLESHOOTING TROUBLESHOOTING GUIDELINES This section provides troubleshooting information by category. Included in this information are symptoms, causes, and suggested tests for further fault isolation. These tests are described in Section 7, listed by Test Procedure (TP) number. BASELINE PROBLEMS Baseline or Signal Offset (TCD) Symptom: Baseline (detector signal) is continually offset to the positive or the negative with no short term drift up or down scale (see Figure 6-1).
Page 172: Cyclic Short Term Drift
8. A continuous presence of sample at the detector due to sample valve leakage. Perform Test Procedure 3 (Sample Valve Leaking/Column Flooding). 9. Filament failure. Perform Test Procedure 6 (Filament TCD Test). Cyclic Short Term Drift Symptom: Baseline (detector signal) is experiencing a cyclic short term drift (see Figure 6-2) indicated by detector signal, graphics display, or strip chart recorder (if used).
Page 173: Baseline Continuous Noise
Perform Test Procedure 3 (Sample Valve Leaking/Column Flooding); or Test Procedure 30 (Checking Temperature Table Values), steps 1 to 3, 8, and 9. Another possible cause could be detector filament deterioration. Baseline Continuous Noise Symptom: Baseline (detector signal) with no sample injection appears as noise similar in appearance to “grass”...
Page 174: Baseline Signal Random Noise (Fid)
b. The gases may be pure, but contaminated tubing or hardware components in the analyzer or cylinder regulator(s) contaminate the makeup gases as they pass through them. The FID detects theses contaminants, resulting in a noisy baseline. c. An FID is generally equipped with a catalytic air cleanup unit to remove hydrocarbon impurities from the burner air.
Page 175: Signal Offset (Fpd)
Perform Test Procedure 11 (Common Usage of Gases), Test Procedure 13 (Burner Air Catalytic Cleanup Unit), or Test Procedure 14 (Coaxial Cable), as applicable. Replace or clean the FID (see "FID REPAIR" in Section 8). Signal Offset (FPD) NOTE Because of the sulfur addition in the FPD detector, the FPD will always have a background level.
Page 176: Analysis Problems
a. Electrical noise from the FPD amplifier could result from a noisy power supply or defective component of the PCB. b. Loose electrical connections can cause electrical signals to be sporadic. c. Since the FPD amplifier input impedances are extremely high, low noise coaxial cable connects the detector and the FID amplifier.
Page 177: Double Sampling
5. Baseline offset extreme. See "Baseline or Signal Offset (TCD)" or "Baseline or Signal Offset (FID)." 6. Column broken or connection in the column train disconnected. Perform Test Procedure 7 (Column Train Problems). 7. TCD Failure. Perform Test Procedure 5 (TC Detector Balance) and Test Procedure 6 (Filament TCD Test), as applicable.
Page 178: Additional Peaks Of Unknown Origin (Mystery Peaks)
Additional Peaks of Unknown Origin (Mystery Peaks) Symptom: Chromatograph displays extra peaks or a noted difference in composite chromatograph appearance from that of the calibration (see Figure 6-10). Unknown TIME TIME NORMAL MYSTERY PEAKS Figure 6-10. MYSTERY PEAKS Cause: If only present on calibration sample and not on process, verify that the correct calibration and proto fuel samples are being analyzed.
Page 179: Variable Retention Times
above the bubble point of the sample, the sample will bubble in the sample chamber, causing an inconsistent liquid fill of the sample loop. This results in a continuously variable sample size. A defective sample valve stem or leaking seal(s) can also cause nonrepeatability. Perform Test Procedure 20 (Variable Sample Size).
Page 180: Peak Inversion
Cause: The gating in the method needs to be modified to ensure gating of the missing peak in the report. This can be done by modifying the gate ON/OFF time in the method table. See "PEAK DETECTION" in Section 4 for detailed instructions. Peak Inversion Symptom: The peaks on the strip chart recorder are reversed or negative (see Figure 6-13).
Page 181: Reduced Detector Sensitivity
The peaks may in fact be too large and saturating the detector or column. The splitter may be out of adjustment, or the liquid sample size may be too large. Possibly the detector gain jumper at the detector electronics is not setup correctly. The sample valve may be injecting an excessively large sample volume due to deformation or a scratch in sample stem or worn seals.
Page 182: Peak Discrimination
Peak Discrimination Symptom: Discrimination is the non linear unequal dilution of hydrocarbons in the column train. Typically the heavier components will tend to dilute more than the lighter components. Cause: Discrimination is usually the result of a leak or incorrectly adjusted sample splitter. The leak or split might cause more of the heavier components to be exhausted out the splitter vent or leak exit than the lighter components;...

Page 353: Variables
For exponential form floating point numbers, a fixed point constant is followed by the letter E and an optionally signed integer with no blanks separating them. Numbers between 0 and 1.0E ±38 approximately can be represented. Negative values are indicated with the unary negation operator (-). Examples of valid floating point constants are: 0.123 -10.123...

and those values can then be accessed by another BASIC program. Thus, the COMMON! array is a mechanism whereby information and data values can be passed between BASIC programs. Another characteristic of the COMMON! array is that the memory allocation is static. That is, the COMMON! array stays around forever and the values are retained between program modifications and compilations.
