Introduction
7820A GC Safety Manual 9
Uncombusted Hazardous Gases
During normal operation of the GC with many detectors and inlets, some of
the carrier gas and sample vents outside the instrument through the split vent,
septum purge vent, and detector exhaust. If any sample components are toxic
or noxious, or if hydrogen is used as the carrier gas, these exhausts must be
vented to a fume hood. Place the GC in the hood or attach a large diameter
venting tube to the outlet for proper ventilation.
