Syr [,n1][,n2]
Define device to use for dilution. Default n1=0, n2=10000. (use diluter 0, volume 10000
microliters)
RackCode
Set the Autosampler rackcode. Consult your Gilson manual for details.
Rows
Number of rows in the sample tray. This is needed for the Tube command to address the correct
row and column correctly.
Cols
Number of columns in the sample tray. This is needed for the Tube command to address the
correct row and column correctly.
Height
Sets syringe height. This is necessary with no standard cuvette sizes, for example, the narrow
cuvettes used on a 320 sample type rack.
Example
Some autosampler examples.
asm ini ‘ Initilialise sampler
asm fil,wash’ load and run sampler program ‘wash.asf’
asm wai’ wait for display END to signify wash complete.
asm dil,5,4 ‘ take the sample in row 1, dilute it 4 times into successive
‘ rows of the same column. Repeat over the first 5 columns.
size mode ‘select size analysis
for i=1 to 25
asm tube,i’ select tubes from 1 to 25
asm wait for tube inject to finish then wash inject line
asm fil,wash
measure sequence 1’ run a measurement
asm wait for the wash sequence to finish
‘ (unless the measurement time is short
‘ this will already have happened), but it is ‘ ‘
