New OrthoPure DID Detector | Orthodyne Gas Chromatography

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.

DID Gas Chromatograph - 600

Laboratory Line

The new line 600 has been designed for working with Chromdyne software on a computer. It make this new system ideal for laboratory process gas analysis. Moreover, the new line 600 can be remotely controlled through Ethernet or Internet.
