20171011· A new sensor to measure VOCs (Volatile Organic Compounds) has been launched by Alphasense. The new ptype Metal Oxide sensor is a broadband total VOC detector with a range of 0100ppm (isobutylene) and 1050ppb detection limit, depending on the VOC.

VOC sensors use a bright ultraviolet light source to knock electrons out of the VOC molecule; the electrons are measured and their flow indicates that VOC molecules are present at the sensor. Each specific type of VOC molecule has an ‘ionization potential’ (IP) value that represents the amount of energy necessary to liberate an electron; this value is measured in ‘electron volts’, or ...

1 VOC Sensors What are VOCs VOC is an abbreviation for Volatile Organic Compounds and a collective term for gaseous carbonaceous substances. Depending on how high the concentration of these substances in the ambient air is, we can perceive them by smelling them with our nose. On average, a person inhales about 15 kg of air per day, 80% of it indoors. Outside air quality is routinely ...

Shortterm exposure to high levels of some Volatile Organic Compounds (VOC) can cause: breathing problems; irritation of the: eyes; nose; throat; headaches; Some people may be more sensitive, such as people with asthma. Most people are not affected by shortterm exposure to the low levels of VOCs typically found in homes. For longterm exposure to low levels of VOCs, research is ongoing to ...

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.

Humans respirate Volatile Organic Compounds (VOCs) as well as CO 2. The BAPI sensor is able to measure these VOCs and indicate when a space is occupied just as well as a CO 2 sensor.
