| Detection System | A Solid-state Infrared detector is used for Oxygen. Thermo-conductivity detector is used for Nitrogen and hydrogen. - Infrared Cells: Two IR cells are installed in the analyzer. The length of each cell can be customized according to the content of samples
- Detector: Solid-state pyroelectric detector made in Germany
- Motor: Synchronous motor made in Swiss
- Source: Anti-oxide, stable IR emitter made in US
- Temperature control: Keep the constant temperature in the whole infrared unit to make sure the temperature of detected gas is stable and the results are accurate
- Protecting gas: The infrared emitter and the detector are separated from the ambient by nitrogen, which can improve the stability and the accuracy
- Thermo-conductivity (TCD) detecting unit: Anti-oxide NTC thermistor
- Signal processing: A small current control technique is developed to make sure the thermistors can be used without carrier gas
- Reference gas circuit: Low flow control technique is used
