VOC Gas Analyzer FID

The GFID VOC gas analyzer measures volatile organic compounds using gas chromatography with a flame ionisation detector (FID), one of the effective methods for detecting low concentrations of organic gas. The analyzer works at high temperature: an air bath heating chamber keeps the chromatographic column and the gas paths before and after it hot. The multi-component sample passes through the special packing of the column and is separated as it flows out. A carrier gas then delivers each component to the FID, where the hydrogen flame ionises the molecules and the released electrons generate a signal current proportional to the quantity of gas entering the detector.

Features

• Measuring range 0.01 … 1000 ppm (as methane) with 0.001 ppm resolution
• Automatic back-flushing of the chromatographic column to speed up separation and analysis
• Inert-treated gas lines prevent adsorption and sample residue on the pipe walls
• Configuration supports multiple detectors for complex sample analysis at the same time
• Touch screen LCD
• Ethernet and RS232 ports; RS485 Modbus RTU, GSM and Wi-Fi communication

How it works

• Air bath heating chamber keeps the column and gas paths at high temperature
• Chromatographic column separates the multi-component gas mixture
• Carrier gas transports the separated components to the FID
• Hydrogen flame ionises the molecules; the high-voltage field collects the electrons as a measurable current

Applications

• Crude oil processing
• Textile and dyeing
• Chemical and pharmaceutical plants
• Metal smelting
• Food and beverage industries
