Super User Calibration Page
The calibration screen has the same appearance as in Normal User mode,
but you now have the option to modify the Rfactor and Concentration
Factor in addition to the Concentration (Conc). For this instrument the
Concentration Factor must be 1 for proper operation.
Concentration and Response Factor Calculation
RF = (AREA / (CONC x VsigAdj)) x Cal Ratio x 65535.0
GAS_CONC = (AREA / (RF x VsigAdj)) x 65535.0
RF
= Response Factor
VsigAdj
= Response Factor Adjustment due to RGD lamp intensity
CONC
= Concentration (or blend) of Calibration Gas Cylinder in
ppb
VSIG
= RGD detector analog voltage in A/D counts
Cal Ratio = 1 (Concentration Factor)
65535.0
= factor used to adjust software VsigAdj based on VSIG,
lamp intensity (VsigAdj = VSIG A/D counts x 2500 / 65535)
Super User Run Screen
The run screen in Super User mode is very different than the functionality
and appearance of Normal User mode.
1. The top line provides current mode, current viewable time, current at-
tenuation, and current time respectively.
2. With the asterisk on the top line, one can toggle between single, cycle
and rerun as analysis options. Single will run one event if the "Run" key
is depressed. Cycle will continuously run the loaded event program until
IDLE is depressed. Pressing IDLE in Super User Mode will immediately
stop the cycle. This can result in the valve remaining in the inject position.
If this happens the valve should be manually returned to load position
(see number 5 below). Rerun will reanalyze the previous chromatogram
with any database changes and display the new results, although, the
new analysis cannot be printed.
