Volatile organic compounds are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility.
- VOCs in the environment or certain atmospheres can be detected based on different principles and interactions between the organic compounds and the sensor components.
- Solid-phase microextraction (SPME) techniques are used to collect VOCs at low concentrations for analysis.
- Direct injection mass spectrometry techniques are frequently utilized for the rapid detection and accurate quantification of VOCs.
