7.2.2 Parameter list
Q Main screen of clean up
• COLUMN OVEN
TEMP
Range: 0.0−400.0 °C, Default: 25.0 °C
Sets the default value of the column oven temperature for the clean up method.
The clean up oven temperature should be 20 to 30 °C higher than the temperature
program used for actual analysis. (Neither temperature should exceed the maximum
temperature indicated on the column).
If the clean up oven temperature exceeds the maximum column temperature, indicate
that the regular analysis parameters should be used for clean up by setting “Analysis
Para” for the start procedure.
•FLOW
Dual packed INJ (DAFC is used)
L column flow rate, R column flow rate
Range: 0.0−100.0 ml/min, Default: 50.0 ml/min
Sets the initial pressure for the clean up column flow rate.
SPL(AFC is used)
INLET PRESS
Range: 0.0−970.0 kPa (Refer to Fig. 12.2.5.), Default: 100.0 kPa
Sets the default value of the column inlet pressure for the clean up method.
PURGE FLOW RATE
Range: Refer to Fig. 12.2.15, Default: 3.0 ml/min
Sets the septum purge flow rate for the clean up method. The septum purge removes
contamination in the injection port near the septum. If the split ratio is set to “-1.0”, the
total flow rate remains fixed regardless of to the oven temperature.
SPLIT RATIO
Range: -1.0/0.0−9999.9, Default: -1.0
Sets the split ratio for the clean up method.
Set the split ratio to “-1.0” for the total flow rate to remain fixed regardless of the oven
temperature.
• INJECTION PORT
Temperature
Range: 0.0−400.0 °C, Default: 250.0 °C
Sets the injection port temperature for the clean up method.
• DETECTOR
Temperature
Range: 0.0−400.0 °C (FID), Default: 250.0 °C
Sets the detector temperature for the clean up method.
For any detector other than an FID, its set temperature must be within the valid range of
the detector.
Makeup flow rate
The range and default value depends upon the kind of detector. Refer to the values
given for each detector.
This sets the flow rate of an inert gas supplied to the detector side during clean up.
• AMC.L, AMC.R
Flow rate
Range: 0.0−100.0 ml/min, Default: 50.0 ml/min
Sets the AMC.L, R flow rate for the clean up method. (Usually equivalent to the flow rate
of the inert gas supplied to the detector.)
