Sources of VOCs

Volatile Organic Compounds (VOCs) are potenially dangerous compounds created by both human industry and natural processes that vaporize under normal atmospheric conditions. VOC levels are much higher in indoor environments as they can be emitted by many manufactured products such as carpet, paint, and cleaning supplies. Outdoor sources can include landfills, industry, and hydrocarbon emissions.
Prolonged human exposure to VOCs have been known to cause respiratory problems, cancer, and neurological damage. Environmental damage can include air, water, and soil pollution.

Detection using a PID

Photoionization Detectors (PIDs) are the easiest and most efficient way to detect VOC levels. Although not as selective without the use of a gas chromatography column, a stand alone PID provides real time measurement of total volatile organic compounds in a portable format that anyone can use. These detectors enable the user to react swiftly to any potential threat, without waiting for the evaluation of a time-weighted average (TWA). Sensitivity can be increased by the selection of Ultraviolet
(UV) lamp, as well as detector range.
