Portable Photo-Ionization Gas Chromatograph GC-4400 uses long life-span vacuum UV lamp and has high sensitivity, low limit of detection with broad linear range. It does not need H2, nor the
combustion-assistant gases. It can perform trace analysis not only for organic compounds but also for some inorganic compounds. Due to the high sensitivity, when analyzing pollutant from indoor
or outdoor environ-ment, there is no need of thermo desorption devices for sample enrichment.
Portable Photo-Ionization Gas Chromatograph has wide applications in fields of environment protection, indoor air quality control, food safety, national defense, anti-chemical war, anti-terrorism war, aviation, aerospace, scientific research, and
others requiring trace gas (vapor) analysis.
Technical Specifications:
Utilize photon to realize ionization of samples. No radiation source.
High sensitivity. Low limit of detection. Broad linear range.
Light weight, manoeuvrable and flexible, especially suitable for use in analysis at scene and emergency for environment pollution accidents.
No need of H2, combustion-assistant gases and high purity gas. Only mixed air gas is needed.
No destrution of samples. The results are safe and reliable.
No need of chemical pre-processing, concentration, enrichment, thermo desorption. The user can directly inject samples to analyze.
Chromatograph workstation, composed of data acquisition card, a notebook computer and software. It carries out of data sampling, analysis, calculation, display and storing.
