■ Overview

■ Application

The function of the SIPROCESS UV600 gas analyzer is based on
UV resonance absorption spectrometry. It also is used to
measure very low NO, NO2, SO2 or H2S concentrations in gases.

■ Benefits
• For NO, NO2, SO2: Very low cross-sensitivity with other gases
• All modules are thermostatically-controlled, and thus
independent of the ambient temperature
• Simultaneous measurement of NO and NO2 with subsequent
calculation of total. Therefore neither an NO2 converter nor a
CLD analyzer is required.
• Measurement in the UV range:
- No cross-sensitivity with H2O and CO2
- Very low SO2 and NO measuring ranges possible
• UV resonance absorption spectrometry:
- Measurement of very low NO concentrations
- Very low cross-sensitivity possible
• Very long service life of UV lamp (usually 2 years)
• Low drifts and high stability thanks to four-channel measuring
method with double generation of quotient
• True reference measurement for low-drift, stable results
• Interface for remote monitoring in networks and linking to
process control systems
• Optional calibration unit
- Filter wheel with calibration cells which can be automatically
swung into the optical path
- Low consumption of calibration gas
- Manual or automatic calibration possible

Fields of application
• Emission measurements
- Measurement of low NO concentrations in power plants or
gas turbines
- Monitoring of NOx in denitrification plants by direct
measurement of NO and NO2, as well as summation to NOx
in the analyzer
- Efficient measurement in desulfurization plants
- Monitoring of very small SO2 and NO concentrations
- Emission measurements in the paper and cellulose industries
• Process monitoring
- Measurement of SO2 in process gases in the paper and
petrochemical industries
- Optimization of NOx emissions in exhaust gas in the
automotive industry
- H2S and SO2 measurements in the residual gas purification
of sulfur recovery units
• H2S measurement
- In typical emission applications
- Taking account of possible cross-sensitivities (e.g. from
mercaptan)
