BACK TO LIST

Overview

Ultraviolet photometry analyzer has 2 measuring ranges as ppm or Vol.-%, and can also realize high-precision up to ppb range. It can measure 2 gas components simultaneously by using 2 UV-LEDs. Nitrogen oxides (NO+NO2), hydrogen sulphide(H2S), ozone(O3), sulphur dioxide(SO2) and chlorine(Cl2) can be measured.


Principle

UV-LED radiation is divided into measurement and reference paths by a beam splitter. The reference beam directly reaches the detector, which converts it into a reference voltage value. Using this reference signal, the aging effect of UV-LED can be almost completely compensated. The measuring beam enters the sample cell, and the gas in the sample cell is absorbed by the radiation in it. The absorption behavior is recorded by the measuring detector and used to calculate the gas concentration in the measuring cuvette. 

The measurement of nitrogen monoxide (NO) requires a selective UV radiation source in the spectral range around 226nm. For this purpose a gas discharge lamp filled with NO is used, which emits precisely the radiation that is required for the NO measurement. The measurement mode also referred to as UVRAS (UV Resonance Absorption Spectrometry).
