High-Sensitivity VOC Monitoring with Reliable Quantitative Analysis

The CI-PC9200 series is an advanced online gas chromatograph designed for continuous monitoring of Volatile organic compounds (VOCs) in industrial exhaust gases, even under complex and harsh environmental conditions.
It is equipped with a high-sensitivity flame ionization detector (FID) and a long-life sample-cutting valve. Under the action of a carrier gas, the sample passes through dedicated quantitative tubes for methane, total hydrocarbons, and benzene-series compounds. These are then directed to corresponding chromatographic columns for separation, followed by FID detection.
The system provides accurate and reliable quantitative analysis of each individual component. With its compact structure and rugged design, it is well-suited for fixed installation in demanding industrial applications.

Product Features:

• EPC Carrier Gas Pressure Control: Employs Electronic Pressure Control (EPC) technology to ensure accurate and stable carrier gas pressure, with a control precision better than ±0.1 kPa;

• EFC Flow Control for Hydrogen and Air: Utilizes Electronic Flow Control (EFC) for precise regulation of hydrogen and air flow, with control accuracy better than 0.5% FS;

• Automatic Ignition & Safety Shutdown: Features an automatic re-ignition system in case of flameout. If ignition fails, the hydrogen supply shuts off automatically to ensure system safety. Built-in over-temperature protection prevents equipment damage;

• Precise Oven Temperature Control: Maintains high thermal stability with temperature control accuracy better than ±0.1 °C;

• Ultra-Long Life Cutting Valve: Integrated cutting valve offers stable air flow and ultra-low maintenance, with reliable operation for over 10 years;

• High-Sensitivity Miniature FID Detector: Equipped with a miniature Flame Ionization Detector (FID) featuring an ultra-low detection limit of 0.01 ppm, enabling extremely high sensitivity for a wide range of organic compounds including total hydrocarbons, non-methane hydrocarbons, ketones, olefins, and alcohols. Offers high detection accuracy and analytical efficiency;
