1、 Overview
GC2002 (N/PDHID) helium ionization gas chromatograph, equipped with a high-sensitivity helium ionization detector (PDHID)
And pulse high-voltage power supply, helium purifier. The instrument is equipped with a four valve multi column analysis system with carrier gas blowing protection. For various
Ultra pure gas has the universal analysis function of front-end component cutting, central component cutting, and back-end component emptying. Configure applicable configurations for different tested gases
A multi column system can achieve the detection of PPb level trace impurities in various ultra pure specialty gases.
2、 Instrument features:
The PDHID helium ionization detector, pulse high-pressure source, helium purifier ensure the highest detection sensitivity and stability;
A multi column analysis system with front-end component cutting, central component cutting, and back-end component blowing and emptying of the tested sample, which has strong adaptability to various analysis samples;
Ten way, six way, and four-way valves with carrier gas blowing protection function and temperature control.
The pre column and analysis column are separately temperature controlled for easy debugging and obtaining separation analysis conditions.
Equipped with a pre flushing system for the injection system, it ensures high injection accuracy, fast stability, reduces the amount of sampling gas, and prevents interference from O2 and N2 in the ambient air.
Equipped with computer reverse control, 10/100M Ethernet communication interface, and built-in workstation, remote supervision can be achieved.
