Overview
This section contains procedures for setting up the following detectors:
FID (flame ionization) PID (photoionization)
ECD (electron capture) NPD (nitrogen phosphorus)
TCD (thermal conductivity) FPD (flame photometric)
The instructions provided in this chapter describe how to set detector gases that are controlled by PPC
modules.
CAUTION
ATTENTION
In a Clarus GC equipped with PPC modules, the modules are calibrated
at the factory with the corresponding gas; however, there are
exceptions. The PPC module that controls the:
•
ECD is calibrated with nitrogen.
•
TCD is calibrated with helium.
•
PID is calibrated with helium.
If you intend to use a gas that is different from the gas used to
calibrate the PPC module, you must recalibrate the PPC module with
the gas.
Dans un Clarus GC équipé de modules PPC, les modules sont étalonnés
en usine avec le gaz correspondant; Cependant, il existe des
exceptions. Le module PPC qui contrôle le:
• L'ECD est calibré avec de l'azote.
• Le TCD est calibré avec de l'hélium.
• Le PID est calibré avec de l'hélium.
Si vous avez l'intention d'utiliser un gaz différent du gaz utilisé pour
étalonner le module PPC, vous devez recalibrer le module PPC avec le
gaz.
The instructional procedures in this chapter are written with the assumption that:
You know how to measure gas flows using a flowmeter with the Clarus GC’s built-in stopwatch. If not,
prior to continuing, please read "Using the Built-in Stopwatch" in Chapter 4, "Before You Install a Column."
