START Command
In standard analysis, a start signal is automatically sent to the LC Workstation (or
Chromatopac) and the OUT terminal as an event when the time program in the analysis
method starts.
The system controller's START command can be used to output this start signal at any time
during a time program.
In order to output the start signal using the START command, set [None] in the
[External Start Output] field in the "Configuration Parameter" window to stop the start
signal being output when analysis starts.
In order to output the start signal as event output, set [Start] for the desired event output
number in the "Configuration Parameter" window.
Completing the Program Setting
Be sure to input the STOP command for the system controller at the end of the program.
Gradient Curve
CURV Parameter
To change the concentration of straight line to curve in gradient analysis, set an initial CONC
value (B.CONC, C.CONC, D.CONC) and CURV value (B.CURV, C.CURV, D.CURV) in the
time program.
Set the CURV value after 0.01 minutes of the CONC value.
To have the concentration vary exponentially from the start of analysis in binary
gradient analysis, set the B.CONC value at 0.01 min and the B.CURV value at
0.02 min.
No other function should be set between CONC and CURV.
If no CURV value is set, the default setting of 0 (= straight line) will be implemented.
Example of Time-program setting:
Time Module Function Value Description
0.01 B.GE1 B.CONC 0.0 Initial concentration
0.02 B.GE1 B.CURV 3 CURV should be set in the next line of CONC.
10 B.GE1 B.CONC 80.0
15 B.GE1 B.CONC 80.0
15.01 B.GE1 B.CONC 0.0
