Protecting the environment is one of the problems of our century. Many laboratories and conduct air testing, water, industrial emissions ... to meet environmental standards and need to be efficient and fair analyzers.
GasMix ™: gas diluter-mixer that allows the calibration of gas analyzers
Power to create standards as a function of the application of time gives more flexibility to the user. Environmental standards such as EN 14212 ( Standard method for the measurement of sulfur dioxide by UV fluorescence ) require a multipoint calibration. Or the gas standards are expensive and the obtaining of various gas mixtures duration is long. These new conditions have created a demand for mixers can produce accurate gas concentrations. GasMix ™ meets these new requirements. Its precision allows to produce optimal blends to the low concentrations. In addition, the mixers range GasMix ™ reduce gas consumption, their automation reduces operator time and the GasMix ™ software is an additional tool to help inventory management
Multitek : sulfur analyzers and nitrogen in the solid, liquid and gas
Environmental regulations require a sulfur content in fuels of less than 10 ppm in Europe and North America. ISO 20846 and ASTM5453 specifies a method by ultraviolet (UV) fluorescence for the determination of sulfur in automotive fuels. Multitek meets these standards.
SO analyzers Calibration 2 , NO-NO X & CO
The entire Airpaca SO2 analyzers park, NO-NOx and CO is evaluated periodically linearity and repeatability.
Tests are carried out automatically with a diluter Alytech GasMix. Automatic sequences were configured on the interface of the GasMix ™.
These sequences are used to assess the linearity of analyzers on their measuring range in six concentrations (80%, 40%, 0%, 60%, 20% and 95%) and repeatability three concentration levels (zero, 95% and national calibration concentration). The measurements are performed according to the methods specified in the standards NF EN 14212, EN 14211 and EN 14626. Linearity The residuals are calculated from concentrations "real" generated, not those calculated from the calibration curve. This implies Diluter calibration on all generated concentrations.
The biogas produced by landfills and sewage digesters, is an excellent source of renewable energy for electricity production. The composition of the biogas produced by these methods is complex and traces of silica compounds are present. Now this type of compounds is prohibited in many applications using biogas as fuel. Indeed, at high temperature, siloxanes are transformed into silicon oxide and corrode the metal surfaces of an engine. It is therefore necessary to propose purification processes, technically efficient and economically viable.
To assess the ability of a number of active carbon to remove siloxanes and hydrogen sulfide in biogas, one of our customers uses a gas chromatograph. This instrument needs to be calibrated gas standards but the siloxane is not easily obtained. LiqMix ™ is used to generate a standard gas from a liquid standard of octamethylcyclotetrasiloxane. This standard siloxane may optionally be mixed with a H2S standard. A trial may last several days.
