Understanding TVOC: What You Need To Know About Volatile ...

VOC offgassing is often passive; you don’t even need to use the products for them to produce tremendous quantities of volatile organic compounds. For example, recently drycleaned clothing can produce perchloroethylene, a probable human carcinogen. Until the strong smell goes away, consider storing these clothes outside, or leave them at the dry cleaners until the smell goes away.

The purpose of a VOC detector on a confined space monitor

· The most common VOC sensor is a photoionization detector because of its small size and weight (similar to EC sensors) and its sensitivity, typically down to ppm. Other VOC sensors, such as infrared sensors and flame ionization detectors tend to have a larger size less suitable for a compact meter, and metal oxide semiconductors tend to be affected by humidity and temperature. Most ...
