Helium ionization (PDHID) ultrapure gas and special gas analysis chromatograph

Helium ionization (PDHID) ultrapure gas and special gas analysis chromatograph

Introduction：

GC2003 (N/PDHID) helium ionization gas chromatograph, equipped with a high-sensitivity helium ionization detector (PDHID), pulsed high-voltage power supply, and helium purifier. The instrument is equipped with a four-valve multi-column analysis system with carrier gas purge protection. It has universal analysis functions for cutting off the front components, cutting the center components, and emptying the back components for various ultrapure gases. For different gases to be measured, suitable multi-column systems can be configured to detect PPb-level trace impurities in various ultra-pure special gases.

Instrument features:

• PDHID helium ionization detector, pulsed high-voltage source, and helium purifier ensure high detection sensitivity and stability;
• The multi-column analysis system with front component removal, center component cutting, and rear component purging and evacuation of the sample to be tested has strong adaptability to various analysis samples;
• Ten-way, six-way and four-way valves with carrier gas purge protection function and thermostatic control.
• The pre-column and analytical column are individually temperature-controlled, making it easy to debug and obtain separation and analysis conditions.
• It has a pre-flushing system for the sampling system, which ensures high sampling accuracy, fast stability, low consumption of sampling gas, and prevents interference from O2 and N2 in the ambient air.
• It has computer reverse control and 10/100M Ethernet communication interface and built-in workstation, which can realize remote supervision.
