CTC Analytics PAL Samplers: PGM File for HS_Progr Inject Mode

GC injections are similar to LC injections. If you want to perform headspace injections, you have to define the appropriate sample preparation steps via the HS_Progr injection mode. A typical program for headspace injections might look as follows:

       Agitator_Temperature.Nominal = 100.0
       Agitator_Temperature.Accuracy = 1.0
       TrayName = "Tray1"
       Injector = GC_Inj1
       InjectMode = HS_Progr
       FillStrokes = 3
       ; Delay times in [ms]:
       PreInjectDelay = 3000
       PostInjectDelay = 5000
       ; Incubation time for the first sample of a sequence in [min]
       IncubTimeStart = 2.0
       ; Additional incubation time of the last sample
       IncubTimeOffset = 1.0
       ; Minimum run time between two injections(buffer: 10min + 1.5min)
       GCCycleTime = 11.5
       ; Agitation times in [s]
       AgitationOnTime = 20
       AgitationOffTime = 10
       ; Defines the agitation speed and automatically starts the agitator
       AgitationSpeed = 250
0.000  Wait Sampler.Ready  
       Inject
       GC_1.AcqOn        
10.000 GC_1.AcqOff
       ; Stops the agitator. If there is a another sample, the agitator is automatically re-started
       ; by the 'AgitationSpeed = 250' command (see above) in the next sample program.
       AgitationSpeed = Off
       End
