OrthoPure DID - Gas Chromatograph for PPB analysis

Analysis of H2, Ne, O2+Ar, N2, Kr, CH4, CO, CO2 and Xe in PPB level.

General

The OrthoPure DID Gas Chromatograph detector has been designed to make use of the variations in electrical conductibility found in highly ionised gas. The ionisation is created by a single high frequency discharge within the detector (HF Plasma), causing a high energy photon emission (24.5 eV). This emission is capable of ionising all the gases within the cell with the exception of the Helium.

Principle

One of the biggest advantage of our OrthoPure Gas Chromatograph DID detector is that a photo-ionised discharge is achieved without any radioactive emissions and without the need to apply excessive voltage being applied to the cell. Another important characteristic of the OrthoPure DID is that the detector operates using just one gas.

This one gas is used as the carrier, the flushing gas and/or the purging gas. This gas can also serve to purge and clean all the valves. The housing does not require flushing gas: no contamination of the gas circuit is possible before detection as the input connection is located directly on the cell of the OrthoPure DID detector.

The power setting of the high frequency oscillator allows for the adjustment of the detector sensitivity, which can reach 0.1 ppb (parts per billion). The detection limit and any background noise are directly related to the quality of the carrier gas, so the use of ultra purity (UHP) Helium as the carrier gas is highly recommended.

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.
