In such a situation, VOC detectors are expected to be widely used for screening, monito
29、ring indoor VOC concentrations, locating sources, controlling ventilation systems, and so on. Therefore, it is desirable to use highly sensitive VOC detectors that can detect a range of VOCs within a building. Reflecting the situation as such, several VOC detectors are commercially available.

45、ISO 16000-29:2014(E)4 PrincipleVOC detectors are designed to detect one or more VOCs as target compounds. Test methods for assessing the performance of VOC detectors are defined. VOC detectors are classified into two categories; one is for specific VOC detection and the other for VOC mixtures (VOCs)
46、. In the case of the specific VOC detector, the target VOC concentration is provided upon testing of a standard test gas containing the VOC as one component. The component of standard test gas for VOC mixture detectors has been determined experimentally as described in Annex C. To improve the reliab
47、ility of VOC detectors, this part of ISO 16000 sets out test methods of VOC detectors which also evaluate response time, stability, poisoning, and so on.There are several types of VOC detectors with different detection principles such as semiconducting type, PID type, and interference-enhanced refle
48、ction type detectors. The principle of operation of the semiconducting type detector depends upon changes of electrical conductance that occur by chemisorption on the surface of the heated sensing element when exposed to gas other than air. Gas concentrations are inferred by measuring the change of
49、resistance. In the PID type detector, the detection principle is based on ionization of gases by ultraviolet radiation from a special lamp of known wavelength, and hence photon energy, usually quoted in electronvolts (e.g. 10,6 eV). The PID type detector can detect most of VOCs. Ionization potential of various substances can be found in the literature or a list can be obtained from the apparatus supplier. The detection principle of the interference-enhanced
