G5 Gas Chromatograph

Adhering to the business philosophy of PERSEE and based on decades of R & D experience, your trusted partner the new generation gas chromatograph G5 with new intelligent electrical control system, professional high sensitivity detector and full range of application solutions has been launched.

◆ Stability

The double adjustment design of voltage-stabilizing valve and stable-flow valve or needle valve is used in the pneumatic system. The use of Digital scale knob achieves the characteristics of high precision, good repeatability, convenient and intuitive flow adjustment

◆ Accurate

The stable gas flow and temperature control combined with high sensitivity detector bring you more accurate qualitative and quantitative analysis results


◆ Intelligent

The computer-controlled system, large-screen LCD display, multiple temperature protection and data network transmission make it possible to realize the laboratory digital management

◆ Powerful

Different configuration of optional injectors and detectors can meet a variety of analysis needs. Anti-control software can realize more excellent expansion of configuration, and it is convenient, time-saving and labor-saving

◆ Injector

Packed column injector and capillary split / splitless injector are optional. Available for the installation of a variety of columns (stainless steel columns, glass columns, capillary columns), can realize the perfect combination of 5 kinds of injections and can load up to three kinds of injectors simultaneously

◆ Detector

Six kinds of high-performance detectors are optional, namely FID, TCD, FPD, NPD, ECD and PID. Three detectors can be installed simultaneously. It is very easy to install additional detectors after purchasing the equipment
