The electronic gases are a vital raw material for the electronic industrial production, such as integrated circuits, display devices or solar cells. Nitrous oxide (N₂O) is also essential for the semiconductor production process. It is the main oxygen source for silicon oxide in the Chemical Vapor Deposition (CVD) process. In combination with GC analyzers for the direct detection of N₂O concentrations, the producers of high purity gases are also on need of impurity detection.

To check the purity levels of N₂O, the nCLD844CMhr “N₂O-Edition” is installed. This model is the first chemiluminescence analyzer, that is able to detect ammonia impurities in nitrous oxide (N₂O).
