ONLINE VOC NMHC ANALYZER WITH FID-GC TECHNOLOGY: Vasthi Instruments Online VOC Analyser with FID-GC technology for monitoring Methane and Non methane components in different industries. Vasthi Instruments has manufacturing and R&D facility in India for VOC analysers with FID-GC technology. Vasthi -NMHC VOCs online analyzer is a high temperature version of Vasthi-3000-NMHC. There is specialized heating box inside for analytic gas path. By adopting air bath heating method, it can make chromatographic column and gas paths before of after it in high temperature condition. During detection and sampling of high-temp. VOCs for specific pollutants (such as diesel engine emission of shipping vessel, flue gas emission of petrochemical refinery and etc.), http://www.vasthi.com/online-voc-analsyer/ it offers heat tracing for sampling gas path/analysis gas path which will effectively prevent gas of high boiling point and low steam pressure from attaching to the walls of ga

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/
