3.16Method for Stopping
First, set the detector gas (hydrogen and air) flow rate to zero. After a while, the monitor value will read 0 and
the hydrogen flame of the detector goes off. After confirming that the hydrogen flame has gone off, set the
FPD detector to [Off]. After that, lower the temperature of [COL], [INJ], and [DET].
For the details of stopping procedure, refer to "7.4 Setting the Stop Procedure" in the GC-2010 Instruction
Maual.
CAUTION
The hydrogen flame must be extinguished before lowering the detector
temperature. If the detector temperature is lowered before the hydrogen
flame is extinguished, water drops are produced around the exhaust
ventilation, resulting in the deterioration of the sensitivity.
CAUTION
In order to protect the filter, the FPD-2010 is so constructed that it is cooled
by the fan provided with the filter. This fan keeps operating as far as the
power is supplied to GC-2010 main unit. Consequently, in order not to make
the service life of the filter shorter, do not turn OFF the power of the 2010
main unit when the column oven and detector temperature is high. After the
temperature has been sufficiently cooled, turn OFF the power of the GC-2010
main unit.
