Gas Chromatography
Gas Chromatography
Features:
★Control system: designed for monitoring and controlling the instrument via the computer.
★Column Compartment/oven with superior thermal performance, multistage (10 ramps) programmed temperature control function. (supported by “control system”)
★Advanced built-in data acquisition system , supporting real time instrument status monitoring, detection signal acquisition and PC control
★Column oven accommodates up to 3 chromatographic columns, and supports quick heat-up and rapid cool-down with automated back-door opening.
★Flexible sample introduction system: 3 sample injectors could be installed and operated simultaneously with independent temperature control.
★High sensibility and stability detector.
★2 independent and analog signals output.
★M6 software, compatible with GLP/FDA-21 CFR Part11 requirements and regulations. (electronic records and signatures)
Gas chromatography and accessories:
Carrier Gas System + Sample Introduction System + Separation System + Temperature Control System + Detector
Carrier Gas System: air source/ purification and desiccation device/ flow rate control device
Sample Introduction System: sample injector
Separation System: chromatographic column(packed column and capillary column)
Temperature Control System (Column Oven): constant temperature and programmed temperature
Detector: FID/ TCD/ FPD/ NPD
Advanced Microcomputer Control System:
★Superior performance with advanced, microcomputer-based temperature control system
★High temperature accuracy (optimum ± 0.02℃), high reliability, and anti-interference
★Self-diagnosis/ self-protection function (overheat protection, power-off protection, etc.)
★Intuitive display of timing program, detector status, measurement range, current setting, etc
