Principle

1) The Hydrogen FID (Flame lonization Director) in VOC analyzer

When volatile organic compound (VOC) burn in a hydrogen flame, high temperatures ionize the gas molecules. This process releases free electrons, which an electric field gradient efficiently directs toward a electrode collector. As electrons accumulate, they generate a measurable ionization current. Since the current strength directly correlates with VOC concentration, analysts use this linear relationship to quantify trace gas components in environmental monitoring and industrial safety applications.

2) Chromatographic Column Separation Process in VOC analyzer

The carrier gas propels the sample mixture toward the chromatographic column’s right end. As the multicomponent gas flows through the column, the stationary phase selectively adsorbs its molecules. Since each gas component interacts uniquely with the stationary phase, their migration rates diverge significantly. This retention time variation enables precise component separation at the column outlet.

Applications

VOC (Volatile Organic Compound) analyzer play a critical role in atmospheric chemistry, acting as key precursors to ozone formation and secondary organic aerosols. Governments now prioritize VOC management, listing them as the fifth major pollutant after COD, ammonia-nitrogen, SO₂, and NOx. Consequently, reducing industrial VOC emissions has become vital for global air quality improvement.

VOC Analyzer in Monitoring System Structure

The VOC (Volatile Organic Compound) analyzer integrates into an online monitoring system for precise industrial emissions control. The system has four key subsystems:

Gaseous pollutant monitoring subsystem uses a sampling probe with a ceramic filter to extract dust-free gas samples.
The flue gas monitoring subsystem employs a TPF-integrated monitor to analyze stacks’ temperature, oxygen, humidity, and flow velocity, while a hygrograph ensures accurate gas moisture measurement.
Calibration and assistant subsystem maintain system accuracy through automated checks.
Control and data collection subsystem houses a centralized control cabinet with an IPC, heating modules, and a high-temperature pump for real-time data processing.

To enhance reliability, an air compressor provides gas for regular pipeline blowback, minimizing condensation risks in heat-traced sampling lines. This VOC analyzer integrates into an online monitoring system supports VOCs emission reduction and aligns with strict environmental compliance standards.
