Calibrating the Oven Temperature
The Clarus GC oven temperature is controlled by a sophisticated software routine
that permits adjustment of the actual oven temperature inside the oven up or
down within a ±10
°C window. This calibration utility is intended for
applications which require precisely matching oven temperatures across several
Clarus GCs, such as the determination of retention indices. The calibration
information is stored in a reserved area of the battery-backed memory.
Required Equipment: A calibrated precision platinum resistance
thermometer with 0.01
°C readout and a probe capable of insertion into the GC
oven.
The following steps summarize how to calibrate the oven temperature:
1. Calibrate the reference thermometer
2. Place the thermometer probe in the oven
3. Equilibrate the oven temperature
4. Enter the required offset value
5. Remove the thermometer probe
Calibrate the Reference Thermometer
Calibrate your reference thermometer according to its instructions. If the
thermometer has been calibrated by an outside service, there is no reason to
recalibrate it yourself.
