OrthoPure FID Gas Chromatograph for PPB analysis

 Analysis of CH4, CO, CO2 & NMHC in PPB

General

The OrthoPure FID Gas Chromatograph is placed in a temperature regulated chamber. It is designed to detect traces of hydrocarbons in neutral gases. The combustion of Hydrogen and Synthetic Air creates a flame in which are burning the organic components contained in the gas to be analysed. When burning, these components produce ions which are collected by an electrode.

Principle

The very weak current obtained in this way is amplified in an electrometer with high gain and directed to a data acquisition system. A polarization electrode is connected on the level of the nozzle and a collecting electrode with adjustable distance make the best results possible. Coupled with a methanizer (UMTR unit), it also detects traces of CO and CO2. The methaniser is foreseen to convert, in a catalytic reactor, traces of CO and CO2 into methane.

This reaction takes place at a temperature of ± 350°C in presence of Hydrogen in excess. With a properly adjusted temperature and flowrate, the efficiency is almost of 100%. When supplied with high purity gases, the detection threshold can reach 1 ppb.
