As a specialist in Evaporation Technology, GIG Karasek has already used complete solututions from the laboratory test to complete System in many international Projects, including in the field of organic chemistry. All Systems are convincing with high process reliability and thus with the highest possible System availability.
Under the Thermo Scientific brand of Thermo Fisher Scientific, Inc. (NYSE:TMO), we help scientists meet the challenges they face in the lab or in the field every day. From routine analysis to new discoveries, our innovations help professionals do the science they need to do, the way they want to do it.
Permeation tubes emits the compound with a constant rate and constant temperature, permeation rate have a exponential dependence from the temperature: it increases around 7% for a increase of 1°C. To generate gas standard with accuracy is necessary a thermostation with accuracy ±0,1°C. The tube (or more tubes) are placed into “U” glass older and immersed in thermostatic bath, the diluent air or nitrogen is pre-heated on bed of glass spheres.
Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.
Common air monitoring applications include:
Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
Asbestos sampling and analysis
