Hitachi 3400-N Using Manual

Using the Hitachi 3400-N VP-SEM

Before You Begin:

Sign in on the Calendar

Wear gloves

when handling anything that goes in the chamber such as stubs,

specimens, sample holders. Finger oils contaminate the machine and destroy image

quality.

Measure your sample's diameter and height accurately:

Improper sample measurements will cause the sample to hit

the detectors and create thousands of dollars of damage!
