Accurately Measuring Volatile Organic Compounds (VOC’s ...

Flame Ionization Detectors (FID)Flame Ionization DetectorFID’s are a historically reliable method of detecting a wide ranges of VOC’s in xed spaces and is a common technology used in laboratories. FID technology works by injecting a gas sample in a chamber which is then introduced to a hydrogen-air ame, where most carbon containing compounds will ionize. These ions produce a current which is …

MOS sensors to measure VOC for ventilation control

All above mentioned arguments speak for MOS VOC sensor technology in comparison to the currently used CO 2 based one. However, recent research shows that simple replacement of CO 2 sensors with VOC sensors is not enough to achieve the desired effect [2, 3, 4]. A ventilation control strategy needs to be tuned specifically for use of VOC sensors so that their potential can be utilized. In ...

VOC Sensors and Monitors - Volatile Organic Compounds

Targeted VOC measurements are useful in controlled environments ( labs, research) where the target compound is used and process control or health and safety risks are required. To measure a targeted VOC, a known correction factor is applied to calculate the relative value from isobutylene that is used for the sensor calibration. However, to ...

VOC Sensors - Belimo

1 VOC Sensors What are VOCs VOC is an abbreviation for Volatile Organic Compounds and a col- lective 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 in-doors. Outside air quality is routinely ...

VOC Sensors: Volatile Organic Compounds Sensor | GDS Corp

VOC Sensor Technology. The most commonly used method for detection of VOCs is a photoionization detector. VOC molecules are complex and easily broken down by high energy photons. 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 ...

FAIMS Technology - Tunable and portable VOC detection

For instance, compared to FAIMS, ‘Electronic Nose’ (eNose) technologies, which use arrays of non-selective chemical sensors, suffer from stability and sensitivity issues. Unwanted chemical interactions between VOC biomarkers and the sensors can lead to poor intra-device repeatability, limited temporal stability and poor chemical selectivity. These problems severely hamper the translation ...
