Industrial air monitoring

Odor monitoring for the paper industry

The paper industry is recognized for its odor nuisance generated by the manufacturing process of pulp paper and other derived products.Chromatotec has developed continuous analysis solutions for monitoring odorous molecules such as sulfur compounds. These control systems can be deployed at several locations on the industrial site, such as smoke extraction chimneys, washing and bleaching (...)

Refineries and hazardous areas

Chromatotec can propose for hazardous areas (for instance refineries) specific boxes for our analysers : category 1 IIc T4 for example. In the United States and in Asia the classification is as follows : Class I, Div II, groups C and D As far as security is concerned only one carrier gas is used air or Nitrogene. It is used as carrier gas for the dilution of the permeation tube for (...)

Industrial hygiene - Personnel Safety

Industrial companies produce during there manufacturing process toxic compounds such as Benzene or H2S. CHROMATOTEC analysers are able to monitor such compounds. For this kind of applications we generally find ranges of 0.1 to 10 ppm. The corresponding analysers for these applications are the chromaFID and the chromaPID, according to technical specifications (gas to be analysed, environment (...)

Waste water treatment plants and landfill

The aim : analyze ppb or ppb of H2S and mercaptans with the TRSMEDOR because of bad smell of exhausts from waste water treatment plants and also the toxicity of H2S and Me-SH. Usually the four Sulfurs involved in the waste water treatment plants are : (fermentation odor) ►Methylmercaptan (Me-SH), odor+toxic ► Dimethylsulfide (DMS) odor ► DimethylDisulfide (DMDS). odor ► H2S odor+toxic ► (...)

Clean air room monitoring

The ambient air in clean air rooms needs to be constantly monitored for the safety of workers and of the production according to the environment. A clean air room is a room where the concentration of particles is controlled in order to minimize the introduction, the generation, retention of particles inside, for instance for chip production or the production of medicines. Thanks to a (...)

Steelmaking process monitoring by Direct MS

Steel, an alloy of iron and carbon (up to 2% of weight), is one of the most widely used construction materials. It is produced by Basic Oxygen Steelmaking (BOS) in a converter : oxygen is blown to form carbon monoxide (CO) and carbon dioxide (CO2) with the carbon excess of molten pig iron. Other chemical elements (such as nitrogen) that may decrease the efficiency of furnace are also removed. (...)

Analysis of VOCs emissions from a car painting line

During car manufacturing, Volatile Organic Compounds (VOCs) associated with the paints are emitted to the atmosphere. These are carcinogen, toxic and lead to tropospheric ozone formation. Therefore, VOC emissions must be reduced. With this aim, Chromatotec® airmoVOC C6-C12 (GC-FID analyzer) has been used to monitor VOC emissions from a car painting line. Indeed, it can measure concentrations (...)
