FID Gas Chromatograph & methaniser (UMTR)

 Analysis of CH4, CO, CO2 & NMHC  in PPB, PPM or % in Helium, Argon, Oxygen, Nitrogen, Hydrogen or Air.

Pattern of Approval Russia | Pattern of Approval China (all certificates)

General

The FID Gas Chromatograph (flame ionization detector) 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.

Type of configurations

DID Gas Chromatograph - 500

Process Line

This new line 500 has been designed for stand alone operation. Easy configuration and quick start-up make this new system ideal for process gas analysis.

In addition to its user-friendly interface (touch screen display), the new line 500 has its own chromatographic software that allows the concentration of each impurity to be displayed directly. Moreover, the new line 500 can be remotely controlled through Ethernet or Internet.
