Syngas Analyzer: Vasthi Instruments Gasification is a technological process that can convert any carbonaceous (organic) raw material such as coal into fuel gas, also known as synthesis gas in short syngas. Generally a high temperature/pressure vessel where oxygen or air and steam are directly contacted with the coal or other feedstocks like coal, biomass, and some waste material causing a series of chemical reactions to occur that convert the feed to electricity, syngas and ash/slag (mineral residues). How Vasthi syngas analyzer works: Vasthi uses heated probe to collect the sample from the sample line, it will maintain constant temperature and removes the dust and mist from the sample gas. This gas sample passes through electrically heated tube to cooler. It will remove the vapour content and cools the gas sample to 5ᵒC dew point range and this sample gas goes through the filter that eliminates the dust particle remaining and finally sensor senses and gives the e...

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/  

Continuous PM10 & PM 2.5 Monitoring Analyzer: Vasthi Instruments VDPM – 6000, Real – Time Portable Beta Attenuation Mass Monitor, continuously measures the mass concentration of ambient particulate matter collected onto glass filter tape with time resolu-tion of one-minute. The VDPM-6000 employs an in-line sampling geometry in which the attenuation of beta rays across filter media is measured and particulate matter is sampled simultaneously. This allows ambient sampling to occur for virtually 60 minutes each hour. It also allows for beta ray measurements to be made for virtually the entire hour thereby improving sensitivity and time resolution. http://www.vasthi.com/continuous-pm10-pm-2-5-monitoring-analyzer/ VDPM – 6000 employs a unique “in-situ” sampling technique where the beta measurement is kept at a near fixed temperature above ambient conditions, thereby minimizing measuremen...
