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

The Cleanroom is a combined laboratory chemical, mechanical and / or electronic whose main characteristic is the presence of very pure air, that is a very low content of fine dust in suspension. In the process of semiconductor production, the airborne particles (micro-powder) go to irreparably damage the micro-photoetched that form the chip, creating an electronic circuit defective, and then discarded. This process has forced the improvement of industrial production environments, removing particles from the air, for two purposes: to increase the efficiency of production, increasing the yield of quality, and requirement of the manufacturer (of course based on the demand of the market) in shrink increasing the area of etching of semiconductors (just think of the USB storage media in a few years, went from 16 MB to 16 GB without changing the external dimensions).

Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives and regulations set. Two major parts of this on-going quality assurance cycle are the QAL2 and AST procedures. A test laboratory performs tests on the systems on-site, and determines whether the systems fulfill the set requirements or not.
