VOCS online monitoring of volatile organic compounds

VOCS online monitoring of volatile organic compounds

1、 Monitoring objects and parameters‌

Support total hydrocarbons（THC）Non methane total hydrocarbons（NMHC）Methane（CH4）Real time detection of benzene derivatives (benzene, toluene, ethylbenzene, etc.) and odorous organic sulfides.

Can synchronously monitor smoke parameters (temperature, pressure, flow rate, humidity, oxygen content) and environmental factors (flow rate, temperature, pressure), achieving multi-dimensional data collection.

System Composition‌

Sampling and preprocessing unitAdopting full process high-temperature heat tracing extraction sampling, equipped with multi-stage dust removal, water removal, and filtration devices to reduce gas interference.

Analysis UnitMainstream technologies include gas chromatography（GC-FID）Photoionization detector（PID）Tunable semiconductor laser absorption spectroscopy（TDLAS）Wait, meet the sensitivity and selectivity requirements of different scenarios.

Data management moduleIntegrated wireless transmission（4G/RS485）Cloud platform integration, local storage（16GMemory, support2-5Annual data recording and intelligent analysis functions (abnormal warning, report generation).

2、 Technical advantages

High precision and stability‌

Use importedPIDSensors or chromatographic methods with detection limits as low as0.05ppmRepetitive error<2%Suitable for ultra-low emission monitoring.

Built in temperature compensation and automatic calibration technology to reduce environmental interference and ensure long-term operational stability.

Intelligence and Security‌

Support automatic calibration, blowback, fault diagnosis, and reduce manual maintenance frequency.

Explosion proof design (for flammable and explosive materials)VOCs）And the pre-treatment system (water gas separation, filtration) ensures equipment safety.

Flexible deployment‌

Supporting various scenarios such as fixed pollution sources (chimneys, pipelines), unorganized emissions at the factory boundary, and mobile monitoring vehicles, adapting to complex industrial environments.

3、 Application scenarios
