Product Overview<\/b><\/strong><\/h3>\n

The CO\u2082 Gas Chromatograph<\/strong>\u00a0is a high-sensitivity, high-selectivity gas analysis instrument, designed for detecting trace CO\u2082 in nitrogen used for food additives and analyzing ultra-trace impurities in high-purity inert gases. The system is equipped with a Hydrogen Flame Ionization Detector (FID)<\/strong>, a conversion furnace (CH\u2084 converter)<\/strong>, and a Zirconia Detector (ZD)<\/strong>, paired with two specialized chromatographic columns. This setup enables precise measurement of impurities such as H\u2082, O\u2082, CH\u2084, CO, and CO\u2082, fully meeting national standards for high-purity nitrogen analysis.<\/p>\n

Working Principle<\/b><\/strong><\/h3>\n

The instrument separates mixed gases using gas chromatography<\/strong>, then sequentially directs the components into dedicated detectors for quantitative analysis.<\/p>\n

    \n
  • FID<\/strong>provides highly sensitive measurement of hydrocarbons.<\/li>\n
  • Conversion furnace<\/strong>converts CH\u2084 for accurate detection.<\/li>\n
  • Zirconia detector<\/strong>measures trace O\u2082, N\u2082, and other inert gas impurities.<\/li>\n<\/ul>\n

     <\/p>\n

    An integrated system with automatic sampling<\/strong>, ten-way valve control<\/strong>, and a computer workstation<\/strong>\u00a0allows seamless data acquisition, storage, calculation, and feedback control.<\/p>\n
