- Model PLC 860 - Photolytic NO2 Converter

From

0

The photolytic converter PLC 860 is capable of selectively converting NO2 concentrations of a few ppt. The PLC 860 is the right choice for NO2 measurements in areas with excellent air quality.

  • Spectrum: 320 nm – 400 nm
  • Sample and calibration flow rate: 0.6 l/min

Photolysis Versus Catalysis

NO2 converters that perform the conversion of NO2 to NO by means of catalysis are well suited for measurement in areas with high concentrations of the respective molecules in the measured matrix. In areas with low concentrations, the conversion needs to be higher in selectivity, since inaccuracies of catalytic converters increase inversely proportional in relation to the concentration of NO2 in the measured gas. In background areas, such as rural sites, mountain tops, sea coasts or polar regions and clean room environments, the concentrations are typically within the range of application of the PLC 860. The photolytic reaction takes place in a specifically constructed reaction cell where the gas is exposed to light at a specific wavelength from a metal halide lamp, that causes the conversion of NO2 to NO with negligible interference of other gases.

Combination With the ECO PHYISCS Analyzers

The PLC 860 was specifically developed for combination with the range of high sensitivity ECO PHYSICS analyzers for optimum precision measurements. Both the control of the valves and the calculations are performed by the ECO PHYSICS analyzer.
