Gas Chromatograph GC-4100 Series
The GC-4100 is a new generation fully automatic gas chromatography analysis instrument designed for high precision, high automation, and high efficiency. It features a high-precision electronic flow control (EFC) device, flexible instrument configurations, and support for multiple injection methods, detectors, and column systems.
About the GC-4100 Series
The GC-4100 fully automatic gas chromatography is a new generation instrument designed and developed based on the concepts of high precision, high automation, and high efficiency. It draws on the strengths of advanced technologies and has excellent performance.
This instrument is equipped with a high-precision electronic flow control (EFC) device, which can expand the gas path according to customer requirements to achieve fully automatic flow control. It has different modes such as pressure control and flow control, offering flexibility for diverse analytical requirements.
Configuration Flexibility
The GC-4100 offers flexible instrument configurations including multiple injection methods, multiple injection ports, multiple detectors, multi-valve and multi-column systems. It can be optionally equipped with headspace samplers and thermal desorption instruments for better adaptability.
Advanced Control
The whole machine realises computer workstation control, which can realise EPC electronic flow control for six-way gas (expandable). Temperature control of the detector and column box adopts fuzzy PID intelligent control. The fourteen-step program heating and rapid automatic cooling improve work efficiency significantly.
