Description

Gas Chromatography, Persee G5 New

Key Features
◆ 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
