Ultra-Sensitive NO/NO2/NOX Analyzer

The Model 200EU is based on the field-proven Model 200E Chemiluminescence Analyzer for measurement of NO-NO2-NOX. The Model 200EU offers sensitivity ranges of 0-5 ppb to 0-2000 ppb, with a lower detectable limit of 50 ppt. This sensitivity is coupled with improved noise and drift specifications for the most demanding ultra-low level measurements.

The time-proven, dependable design of the Model 200E has been combined with an enhanced performance pump and a special low noise photomultiplier tube for greatly improved performance. In addition, a pre-reactor separates the NO-NO2 reaction from the background chemiluminescence, allowing accurate auto-zeroing of the analyzer. The overall effect of these enhancements is an improved signal-to-noise ratio allowing much more sensitive measurements and minimizing interferences.

Like all instruments in the TAPI E Series, the Model 200EU includes built-in data acquisition capability using the analyzer's own internal memory. This allows the logging of multiple parameters including averaged or instantaneous concentration values, calibration data, and operating parameters such as pressures and flow rates.

Stored data are easily retrieved through the serial port or optional Ethernet port via APIcom or from the front panel, allowing the operator to perform predictive diagnostics and enhanced data analysis by tracking parameter trends.

Multiple averaging periods of one minute to one day are available automatically or manually. The Model 200EU can be used with an external NOy converter for measuring reactive oxides of nitrogen.
