    Gas monitoring instruments and systems for DeNOx process control

    In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

    Chemiluminescense based analyzer for semiconductor applications

    NOx detection is an innovative approach in CMP (Chemical Mechanical Polishing) process control. CMP smoothens the wafer surface with a combined chemical and mechanical polishing procedure. During production, wafers are coated by a thin layer. To avoid damage to the wafer surface, for instance by stress cracks, the NOx emitted as soon as the wafer is plane and blank must be measured. Therefore, a high-resolution NOx-detector, capable of determining exactly when the polishing process must be stopped, is essential....
