CI-XT5100 Fixed Pollution Source VOCs Online Monitoring System
The CI-XT5100 system adopts a full-process high-temperature extraction method for sampling, and utilizes gas chromatography with flame ionization detection (GC-FID) technology to perform real-time online monitoring of volatile organic compound (VOC) emissions from stationary pollution sources. It is suitable for monitoring total hydrocarbons, methane, and non-methane hydrocarbons in exhaust gases from industries such as pharmaceuticals, petrochemicals, paints, and chemicals.
Feature:
-
Detection Principle: Utilizes gas chromatography with hydrogen flame ionization detector (GC-FID), an internationally recognized standard for VOC monitoring.
-
High Sensitivity: Delivers stable and reliable performance with minimal maintenance.
-
Online Monitoring: Enables real-time detection of VOCs in industrial exhaust gas under complex and harsh environmental conditions.
-
Full Heat Tracing: Maintains high temperature from sampling probe to analyzer, avoiding water removal and preventing loss of sample components.
-
Data Accuracy: Ensures precise and effective measurement results with no component loss during transmission.
-
Monitoring Range: Capable of measuring methane (CH₄), total hydrocarbons (THC), and non-methane hydrocarbons (NMHC) to meet diverse application needs.
-
Pretreatment System: Complies with technical standards for VOC online monitoring in stationary pollution sources.
-
Material Selection: Uses corrosion-resistant and inert materials to reduce gas adsorption and preserve sample integrity.
