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

General

The DID Argon Gas Chromatograph has been designed to exploit the variations of high frequency discharge in Argon. The carrier gas (Argon) is passing through a detection chamber where it is submitted to a strong electromagnetic field fed between two electrodes by a high-frequency generator.

Principle

The DID Argon Gas Chromatograph has been designed to exploit the variations of high frequency discharge in Argon. The carrier gas (Argon) is passing through a detection chamber where it is submitted to a strong electromagnetic field fed between two electrodes by a high-frequency generator.

In these conditions, luminescence takes place. The characteristics of the luminescence are modified by any impurity present in the initial gas passing through the chamber.

The luminous intensity of the discharge particularly gives, under well defined detector working conditions, a stable, continuous and linear function of gas composition for each impurity.

The luminous intensity of the discharge is measured by means of a photoreceptive cell which is part of the bridge, the unbalanced voltage of which becomes, after amplification, the output signal of the instrument.

Type of configurations

DID Argon - 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.
