Hydrogen chloride analysis using helium ion gas chromatography

1Hydrogen chloride analysis using helium ion gas chromatography

AGC NovaCHROM1000Hydrogen chloride analysis using helium ion gas chromatographyUsing DID helium ionization detector, mainly used for analysis of H2, O2, N2, CH4, CO, CO2, etc. in high-purity hydrogen chloride.

AGC NovaCHROM1000， All connection interfaces use 1/8'VCR to ensure the airtightness of the instrument. The installed valve has undergone strict leakage testing and is installed in a casing with He gas blowing, isolated from the atmosphere. Therefore, environmental pollution is eliminated, ensuring that the instrument has more stability, sensitivity, and longer service life.

4、 Technical advantages:

Core components of chromatograph----The DID HFADD FID TCD detector from AGC company is based on the independent research and development of AGC company in Ireland. It has strong performance, high sensitivity and stability, and is the choice for analyzing low content impurities in high-purity gas;

*Parallel connection of dual detectors----AGC company has developed dual detectors for parallel use, equipped with two independent detectors. Their temperature control system and operation are both independent detectors, which can be connected in series or parallel.

Gas path system of chromatograph----The unique center cutting and blowback system technology can complete the analysis and detection of multiple complex components at once;

Chromatography software system----Trend Vision, specially developed for AGC chromatography, can not only complete test reports, automatically analyze/store data, automatically draw spectra, reverse control gas chromatography, adjust retention time and various cutting actions, but also control up to 4 analytical instruments simultaneously;

Carrier gas purification system----The AGC 75-802 carrier gas purifier is a renewable purifier that can purify 5.5N grade gas to above 7.5N. The ultra-high purity carrier gas gives the AGC high-purity gas chromatograph higher sensitivity;
