Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.
VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s range of Indoor Air Quality monitoring instruments. The Wireless IAQ Profile Monitor can continuously monitor up to 7 customer specified parameters (including VOC’s).
Sources - Household products including: paints, paint strippers, and other solvents; wood preservatives; aerosol sprays; cleansers and disinfectants; air fresheners; stored fuels and automotive products.
Health effects - Eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage to liver, kidney, and central nervous system. Some organics can cause cancer in animals; some are suspected or known to cause cancer in humans.
Industries - In offices, VOC results from new furnishings, wall coverings, and office equipment such as photocopy machines, which can off-gas VOCs into the air.
Guidelines and Legislation - In most countries, a separate definition of VOCs is used with regard to indoor air quality that comprises each organic chemical compound that can be measured as follows: Adsorption from air on Tenax TA, thermal desorption, gas chromatographic separation over a 100% non polar column (dimethylpolysiloxane). VOC (volatile organic compounds) are all compounds that appear in the gas chromatogram between and including n-hexane and n-hexadecane.
Sensor - Range ca. 0-20ppm, Resolution 0.01ppm, Response time: 60s. Output: Serial output.
The Mini IAQ Profile Monitor can contain a maximum of 5 sensors. Both these instruments send the collected IAQ data wirelessly to the control pc/laptop in real-time; a large number of units can be networked together to enable accurate monitoring of an entire building.
The PPMonitor software enables the data to be viewed graphically, produce reports and statistical data, run schedules as well as alarm functions and notifications for more effective and economical building management.
