For some materials, UV-VIS is preferred because it will distinguish between different oxidation states of the material. , hexavalent chromium) from total chromium, which is useful because Cr6+ is a recognized human carcinogen. X-ray diffraction (XRD) and similar tests are based on the principle that a beam of X rays is affected by crystals in compounds in such a way that the amount of the material can be measured. , quartz, cristobalite, and tridyimite) in air, settled dust, or bulk samples.

Multiple sensor devices. Equipment manufacturers offer single instruments combining several of the detection principles described above to measure the concentrations of more than one gas or vapor. Typical devices have a specialty sensor such as a photoionization detector, gas chromatograph, or infrared detector along with several electrochemical or metal oxide semiconductor sensors. These instruments are valuable for measuring the overall level of chemicals in the air plus several specific compounds.
Other (Nonchemical) Analytical Techniques. Gravimetric analysis means that the filter or other sample collector is weighed to determine the amount of particulate matter collected. This is a nonspecific technique: All material on the filter is included even if it is not the contaminant of 21 interest. While most contaminants are now determined using other analytical methods that give the quantity of the compound in the air sample, materials such as wood dust, coal dust (<5% silica), metal working fluid mist, cotton, and grain dust are still measured gravimetrically.
