Trace-level, Photolytic, True NO2/NO/NOx Analyzer​

Model T200UP - Teledyne Advanced Pollution Instrumentation (TAPI)

The Model T200UP provides trace level measurements of NO and NO2 using our Model T200U NOx analyzer combined with a patented high efficiency photolytic converter. Even low temperature molybdenum converters transform other nitrogen-containing compounds such as HNO3, PAN, etc. to a considerable extent. Simultaneous measurements of NO2 performed with molybdenum and photolytic converters have shown significantly different results in the presence of such compounds.
