Gas Chromatograph - QualiGC™ 5000 Series
Gas Chromatograph with Large Volume Injection and Capillary Flow Technology - QualiGC™ 5000 Series
The QualiGC™ 5000 Series large volume injection gas chromatograph gives research and production labs a fast, connected platform for trace and complex separations. It injects more than 500 µL per run, pairs that with electronic pressure control accurate to 0.001 psi, and adds capillary flow connections for comprehensive two-dimensional GC×GC work. A fast oven heats at up to 120°C/min and cools from 450°C to 50°C in under four minutes. Labs get lower detection limits and shorter cycle times from one instrument.
Qualitest offers the QualiGC™ 5000 Series to labs that run demanding methods every day. Petrochemical analysts use the second column oven for refinery gas, while power utilities monitor plant gases and dissolved gases in transformer oil. Food labs screen pesticide residues, solvent residues, and sweeteners. Detector options include FID, ECD, TCD, and a proprietary cold atomic fluorescence detector for selective trace work.
The control system runs on Linux and uses the MQTT protocol. Operators can check status, edit methods, and manage several chromatographs from a phone or remote PC without opening a workstation. A built-in expert system tracks instrument stability and detector performance and points technicians toward the right maintenance. This machine proven good through thermal testing, reliability growth testing, electromagnetic compatibility checks, and MTBF validation for long service life.
