Vasthi Instruments manufacturer & designer of AAQMS in India. Vasthi Sulphur dioxide (SO2) analyzer for monitoring the So2 Levels in ambient. It applies UV fluorescence technology recommended by US EPA as federal reference method for trace level SO2 measurement of AAQMS.

Key Features: Compliance with US EPA reference methodVarious outputs include Ethernet and RS232User friendly interface with large screenContinuous system diagnosis with alarmMulti-tasking software allows viewing test variables while operatingTemperature and pressure compensationInternal data logging with 1 min to 365 day multiple averagesCritical orifices provide flow stability

Principle: Vasthi Instruments measures the intensity of the characteristic fluorescence released by SO2 in an ambient air sample contained in the gas chamber when the air sample is irradiated by ultravioletlight passed through the chamber.

Vasthi Instruments Vasthi Nitrogen oxides (NO- NO2 -NOX ) analyzer for measuring the Nox levels in the ambient (CAAQMS) purpose. It utilizes chemiluminescence technology indicated by US EPA as federal reference method for monitoring on multiple forms of nitrogen oxides.

Key Features:Permeation dryer on Ozone generatorCatalytic Ozone scrubberIndependent ranges for NOx, NO and NO2Compliance with US EPA reference methodVarious outputs include ethernet and RS232User friendly interface with large screenContinuous system diagnosis with alarmMulti-tasking software allows viewing test variables while operatingTemperature and pressure compensationInternal data logging with 1 min to 365 day multiple averages

Principle: Nitrogen oxides in ambient are measured indirectly by photometrically measuring the light intensity, resulting from the chemiluminescent reaction of nitric oxide (NO) with ozone (O3 ).

NO2 is first quantitatively reduced to NO by means of a converter. NO, which commonly exists in ambient air together with NO2, passes through the converter unchanged causing a resultant total NOx concentration equal to NO + NO2.

A sample of the input air is also measured without having passed through the converted. This latter NO measurement is subtracted from the former measurement (NO + NO2) to yield the final NO2 measurement.

PMT: The optical filter(660nm) attached on PMT provides reliable measurement, and temperature are controlled between 68 with only 0.1 fluctuation by a thermoelectric cooler, ensure the measurement stability.

Ozone generation:Permeation dryer are introduced in ozone generation to provide long system durability without any replacement.An catalytic ozone scrubber is standard for maximum safety and pump life before exhaust.

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 worksVasthi 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 5C dew point range and this sample gas goes through the filter that eliminates the dust particle remaining and finally sensor senses and gives the exact readings in syngas analyzer.
