Commands and Tips for Third-Party Devices
CTC Analytics PAL Samplers: PGM File for Custom Inject Mode

The Custom injection mode supports special LC injections, e.g., from different trays with irregularly distributed sample positions and varying injection volumes.

The Inject command only defines the injection. You have to define all sample preparation steps and the injection procedure in the PGM File. The Inject command is the last command in the injection procedure.

A typical program for the Custom injection mode might look as follows:

; Pump/detector commands

 ...

; PAL commands

 InjectMode = Custom

; Preparation steps of the PAL Sampler

 Wash WashStation=Wash1, WashCycles=1

 WashWithSample; WashCycles=2

; Injection procedure

0.000  Wait Sampler.Ready

 GET_SAMPLE Source=Tray01, Index=Sampler.Position,

Sample_Volume = Sample.Volume

 SWITCH_INJ_Position = Standby

 SWITCH_INJ Injector=LCInj

 PUT_SAMPLE Destination=LCInj, Index=1

 SWITCH_INJ_Position = Active

 SWITCH_INJ Injector=LCInj

 Inject

; (The Inject command completes the injection procedure)

 UV.AcqOn

 . . .

; Cleansing steps of the PAL Sampler

 Wash WashStation=Wash1, WashCycles=1

 WashInjector WashStation=Wash2, Injector=GC_Inj1,

 WashCycles=1

10.00  UV.AcqOff

 End
