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:
•
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.
•
Flame thermionic detector (FTD and WFTD) allows to use
two possible control modes -
Current
and
Voltage
.
Signal Polarity
This field is only present when using the dual detector in the
Dual
mode or one of TCD detectors. Sets the polarity of the
dual data, or in other words, the method of data calculating
(either the signal of the right cell minus the signal of the left
cell (polarity
-
) or vice versa (polarity
+
)).
Range
Applies on the analog detector signal before its processing to
the digital data directly in the
Shimadzu GC-2014C
. This
value serves for the compensation of the overly high signals.
Current
Serves for entering the value of current set on the detector.
Possible range and units depend on the type of the detector -
FTD
detector has the range of values
0.00-10.00 pA
,
ECD
detector
0.00-2.00 nA
and
TCD
detector
0-200 mA
. This field
is only present for Electron capture (ECD), Thermal
conductivity (TCD) and Flame thermoionic (FTD and WFTD)
detectors.
Signal Output Port
Specifies the signal output of the particular detector.
Shimadzu GC-2014C
provides up to 4 signal outputs set in
the
Shimadzu GC-2014C Setup - Signals
dialog (for more details
see chapter
Shimadzu GC-2014C Setup
on pg.
19
).
Power Controller
This field is only present on tabs of Flame thermoionic
detectors (FTD and WFTD).
Adjust Time
This field can only be edited when the
Power Controller
checkbox is selected.
