Product Introduction

XHVOCMS3000BThe volatile organic compound monitoring system can perform real-time and online monitoring of VOCs in the ambient air to reflect the concentration of hydrocarbons in the atmosphere. The system consists of an injection unit, a quantification unit, and an analysis unit, and all controls and calculations are automatically completed by a computer.

measuring principle

The method of separating methane from total hydrocarbons through chromatographic column separation, valve switching, backflushing, and other means, allowing non methane total hydrocarbons to separate peaks and directly determine their concentrations.
