Ultraviolet Differential Optical Absorption Spectroscopy Gas Analyzer(UVDOAS)



UVDOAS Gas Analyzer: 

Vasthi Instruments UV DOAS Gas analyser for Sox, Nox and other emission monitoring as per CPCB Guidelines.The module uses the long optical path UV DOAS technology. Its optical technology platform consists of light source, gas chamber, optical and spectroscopic (including diaphragm, holographic grating, linear array detector) and other optical components.The same gas has different absorption in different spectral band, the absorption of different gases in the same spectral band has superposition effect. Through the analysis of continuous spectrum, a variety of gas can be measured at the same time. The holographic grating is used for light splitting of light absorbed by gas to be measured, sensor array is used to convert the spectral optical signals into electrical signals, after obtaining the continuous absorption spectra of medium, and a variety of gas can be measured at the same time.http://www.vasthi.com/uvdoas-gas-analyzer/

Vasthi Instruments Sulfur dioxide Analyzer using Ultraviolet fluorescence principle, combined with the most advanced microprocessor technology provides accurate, reliable low ppb-ppm levels of SO2, suitable for atmospheric monitoring and dilution of pollution online monitor application. Work is the basic principle of UV fluorescence method for sulfur dioxide Analyzer. SO2 reception of ultraviolet energy excited state molecules return to ground state, issued a characteristic fluorescence, fluorescence intensity of material can be quantitatively measured. Through the use of regular measurement of dark current compensation enlarger PM d drift and corrected using the reference detector UV lamp intensity change, and improve the stability of measurements. Removal And unique optical design of efficient hydrocarbon removal effectively eliminates inaccuracies created by interference.Download Catalog Download Specification
