Heated Zones
WARNING
Risk of burns. Never touch a heated Clarus SQ 8 MS transfer
line or a GC injector cap with bare (unprotected) fingers.
AVERTISSEMENT
Risque de brûlures. Ne touchez jamais une ligne de
transfert chauffée Clarus SQ 8 MS ou un capuchon injecteur
GC avec des doigts nuisibles (non protégés).
Heated zones should be treated with caution. For example, the transfer line, injector
caps, and detectors. In addition, the detector cover may get hot, especially if flame
ionization detectors are operated at high temperatures. As a general rule, allow
heated zones to cool before attempting to work in the GC oven, on the transfer line,
on an injector, around the detector areas or inside the Clarus SQ 8 manifold. Proper
cooling of the transfer line may take from 1/2 to 1 hour.
Using Hydrogen, Methane or Isobutane
WARNING
Explosive Hazard. If the hydrogen is turned on without a column
attached to the injector and/or detector fittings inside the oven,
the gas could diffuse into the oven creating the possibility of an
explosion.
If the mass spectrometer is not under vacuum, hydrogen,
methane, or isobutane can fill the vacuum chamber thereby
creating an explosive hazard.
To avoid possible injury, do not turn on the hydrogen unless a
column is attached, all joints have been leak-tested, and the mass
spectrometer is under vacuum with the forepump exhaust
properly vented to a fume hood.
