Effect of VOC on ozone detection using semiconducting sensor with …

01/03/2012· The conductance of the sensors in ozone decreased due to the contamination of the same VOC levels. At around 200 ... Ozone, which is known as an oxidation agent, can react with many kinds of volatile organic compounds (VOC). In the gas phase, several saturated hydrocarbons, such as methane, ethane and hexane, are oxidized by ozone resulting in conversion into corresponding …

Gas Sensitive Semiconductor (GSS) Technology | Aeroqual

Most independent experts who have tested our GSS ozone sensor agree the sensor is best-in-class for measuring ozone at low concentrations – particularly in the 1 to 100 ppb range. The sensors are consistently able to perform similarly to an ozone analyzer that costs 10x the price. Gas Sensitive Semiconductor (GSS) technology is exclusive to Aeroqual. It is the application of smart …

Effect of VOC on ozone detection using semiconducting sensor …

These sensors responded to sub-ppm levels of ozone, and the sensitivity decreased with increasing working temperature. The response to ppm ozone was ca. 1000 at 250 °C. The conductance of the sensors in ozone decreased due to the contamination of the same VOC levels. At around 200 °C, the cross sensitivity of some VOCs to ozone was quite depressed. The partial substitution of Co for Fe …

Indoor Air Quality | Sensirion

This VOC Index provides a practical quantification of VOC events relative to each individual sensor’s typical indoor environment. In this way, it behaves similarly to the human nose, which is highly susceptible to changes in odor, but it also detects VOC events that are not perceived by humans. The VOC Index indicates to what extent the indoor air quality has deteriorated or improved compared to …

VOC removal - Ozonetech

Ozone quickly reacts with the emitted VOC, oxidizing them without harmful byproducts. This results in a great VOC treatment, with an outlet concentration below the most stringent environmental limits. We always offer our RENA Pro solutions with a tailor-made design, specifically engineered for each case. We consider relevant inlet parameters such as air flow and VOC concentration, dosing the right amount of …

Gas Sensors volatile organic compound -

Some VOCs, such as styrene and limonene, can react with nitrogen oxides or with ozone to produce new oxidation products and secondary aerosols, which can cause sensory irritation symptoms. Health effects include eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage to liver, kidney, and central nervous system. It is believed some VOC's can cause cancer with long term exposure. …

VOC Sensor Capabilities and Limitations - Application Note - …

Opposite examples are sulfuric acid, nitric acid and ozone. These three are “oxidizing gases” (rather than “reducing gases”) and will NOT cause the VOC sensor ppm output to increase. OSHA has set an exposure limit for sulfuric acid of 1 mg/m3 TWA (time weighted average); however, a BAPI VOC sensor is not the appropriate tool to monitor sulfuric acid or any other “oxidizing gases”. VOC Sensor …
