CTC Analytics Combi PAL® and HTS PAL for Front-End Automation for LC and GC applications

Parts, Support, Repair

Founded by the former employees of CHROMSYS® LLC, AUTOSAMPLER GUYS promotes Peak PAL Performance by offering focused support for any standard CTC autosampler, including the HTS, HTC, LC-Mini, Combi PAL, and GC PAL models. AUTOSAMPLER GUYS has been certified by CTC Analytics AG to provide service and support for their PAL products.

The Combi PAL autosampler is able to perform liquid and headspace analysis. Headspace analysis options include Solid Phase Microextraction (SPME), SPME Arrow and ITEX (type of purge and trap).

The HTS PAL autosampler dramatically increases sample throughput by offering automated sample prep, Peltier cooled sample storage using the cooled stack, and low carryover due to the self-cleaning DLW (Dynamic Load and Wash) module and specially coated x-type syringes.

AUTOSAMPLER GUYS offers Certified Pre-Owned PALs. Our certification process includes a complete strip down, repaint and rebuild. We replace all motors, flatband cables, flush tubes, worn toothracks and gears. All sensors and boards are verified and updated to work with the latest PAL firmware. All cooled elements are tested for at least a 1 week’s stress test. PALs can be custom configured to your needs. Please contact us for a quote.
