AS120 Stepper Motor Driven GC Autosampler

The AS120 is an all-electric, stepper motor driven XYZ GC Autosampler providing rugged reliability and pinpoint injection accuracy. The syringe mechanism moves back-and-forth and in-and-out across the sample tray to access sample vials, multiple solvent vials, standards, etc. Variable inject volumes, injection speed, needle dwell times, number of samples per vial, multiple methods per run, solvent flush, air gaping, dual column operation and a host of other autosampling options are all standard and easily programmed on the AS 120’s menu driven keypad. The unit uses screw-cap or crimp-top septum vials and easily interfaces with your GC system with all the remote inputs/outputs—ready signal, injection mark, etc.—plus RS 232 for direct communication with a PC. Mounting is easy and allows for quick changes between GC’s if desired. Syringe/injector alignment is via the keypad. The control module mounts on either side of the GC Autosampler for easy access.
