4.2.3 Method Setup - GC - DET 1 (..4)
Fig 10: Method Setup - GC - DET 1
This tab allows to set the parameters for a detector configured in the
Shimadzu GC-201x Setup
dialog. Particular fields may vary, according to
the type of the detector set. The fields dealing with flow of gases are
available only for models of chromatograph equipped with Advanced
Pressure Control (
APC
). These are
GC2010
and
GC2014 APC/AFC
.
On/Off
Switches the detector on and off. The detector switched off gives
0
as a
resulting signal.
Filter Time Const.
The value set here influences the processing of the detector signal. It
works as a noise filter, the higher the constant, the lower the noise. On the
other hand, usage of the higher values will flatten peaks and may cause
lower or smaller peaks to disappear.
Control Mode
Sets the mode of operation of the particular detector. Two option sets are
available in this field, depending on the type of the detector used:
l
Dual flame ionization detector (WDFID) may work in the
Dual
mode or use
the signal from one cell only. Dual detector can also measure only on
single cell - then select
Single L
for the left cell or
Single R
for the right
cell.
l
Flame thermionic detector (FTD and WFTD) allows to use two possible
control modes -
Current
and
Voltage
.
