Description:
The Draw command (Draw for the ASI-100, Suck for the GINA 50/GINA 160) induces the autosampler to draw a specific Inj. Vol. (injection volume) from a certain sample vial (Pos. (Sample position)). The amount of time this operation is allowed to take is determined for the GINA50 autosampler via the Duration parameter.
Function:
When the operation is completed, the autosampler communicates the Sampler.Ready signal (for the ASI-100; Sucked for the GINA 50/GINA 160) back to Chromeleon. The time interval between the Draw (or Suck) command and the Sampler.Ready (or Sucked) response signal can vary, depending on the instrument type.
Examples:
ASI-100 Autosamplers: The following command sequence delivers 10 µl of the current sample to the RA1 vial. The Dispense command is not executed until the Draw process has been completed.
-1.000 PrepSubject Sample_Vial
PrepVolume 10
Draw
Wait Sampler.Ready
-1.000 PrepVial RA1
PrepSubject PrepVial
PrepVolume 10
Dispense
GINA 50 autosampler: The following command sequence is required to deliver 10 µl of the current sample to the vial 1. Again, the Dispense command will not be executed until the Draw process is completed.
-1.000 Draw Volume=10
Wait Sampler.Ready
Dispense Pos=1, Volume=10
Parameters (GINA 50 only):
Position
Sample position
Volume
Sample volume
Duration
This parameter indicates the minimum time required by the autosampler for the respective operation.
Tips:
For highly viscous or low-boiling liquids, more time must be allowed for the autosampler to draw the exact volume without bubbles.
In manual operation, the commands are selected via the control pull-down of the unit window. When entering the commands in a Program, you do not have to specify the three parameters. During execution of a program, the missing parameters are replaced by the current sample position, the current inject volume, and by the value 0 (if there is no Duration), respectively.
