XHVOCMS3000B Air Volatile Organic Compound Monitoring System Introduction: The XHVOCMS3000B volatile organic compounds monitoring system can monitor VOCs in the ambient air in real-time and online, in order to reflect the concentration of hydrocarbons in the ambient air. The system consists of an injection unit, a quantitative unit, and an analysis unit, with all controls and calculations automatically completed by a computer. measuring principle A method for directly determining the concentration of non methane total hydrocarbons by separating methane from total hydrocarbons through chromatographic column separation, valve switching, and backflushing. Technical parameters: Analysis components: methane and non methane total hydrocarbons, the instrument's analysis method adopts direct method (including pre concentration); Measurement range: 0-1000ppbC; Analysis period ≤ 15 minutes; Zero drift ≤ 0.1% of full scale/24 hours; Span drift ≤ 0.5% of full scale/24 hours; System detection limit: Non methane total hydrocarbons ≤ 20ppb (measured by carbon); Reference standard: Comply with the relevant indicators in the Technical Regulations for Continuous Automatic Monitoring of Non Methane Total Hydrocarbons in Environmental Air.
