Product Description

TH2000 Gas Pretreatment System with Dehumidification and Filtration for Gas Analyzers

Product Description

Differential Optical Absorption Spectroscopy or DOAS, is based on the principle of measuring the differential absorption of the incoming signal in the wavelength region of interest after it has passed through a gas
medium.  It uses a broadband light source and the measurement is made over a large wavelength range
(like FTIR and NDIR, and unlike TDL that uses a very narrow wavelength range).  In general, overlap of
absorption features of several gases is observed.  This requires the use of multiple regression methods of     analysis. The concentrations of a gases are calculated by comparing the absorption signals with their stored reference signals.  As in any broadband measurement technique, interference from other gases must be
taken into account and corrected for to improve accuracy of measurement.  This requires a prior knowledge of the gas composition before the final measurements can be made.

DOAS is capable of measuring more than one species which either absorb in the same wavelength region (continuous monitoring of the species; e.g., NO, NH3, SO2 etc.) or in different wavelength regions (time-    shared monitoring of the species; e.g., NO, NO2, HCHO etc.).

 

Product Feature

High Measurement Accuracy
•   The minimum detection limit of SO2, NO, NO2 can be 1mg/m3 ( 15 m optical path)
•    Ultraviolet has no moisture absorption: undisturbed by moisture and dust.
•    No cross interference between the gas being measured
•    NO and NO2 can be measured at the same time, dispense with converter.
•    Low detection limit.
High Reliability
•    DOAS + PLS technology, small amount of zero drift and span drift
•    Modular design
•   Available version with external UV bench for use with toxic or corrosive gases.
•    No optical moving parts and no vibration influence.
•   Strong gas cell, low cost.
•   Spectrum automatic adjustment technology, long free maintenance cycle
•    Light source adopts the pulse source; the service life is 10 years
European Compliance
•    Low Voltage Directive 2014/35/EU
•    EMC Directive 2014/30/EU
