How Does a TVOC Sensor Actually Work?

There are a number of ways to measure VOCs, with pros and cons based on the situation, budget available, etc. Historically, laboratory techniques such as flame ionization detectors or gas chromatography–mass spectrometry were used, providing an accurate way to identify specific gases within a sample.

E24 Common VOCs Detected Air Quality & by the BAPI VOC Sensor ...

by the BAPI VOC Sensor Rev. 03/17/11 Depending on the source of the information, 5,000 to 10,000 unique Volatile Organic Compounds (VOCs) exist. BAPI’s VOC sensor reacts to all of them. VOCs are chemicals that contain carbon and have boiling points below 100°C. Most can be vapors at room temperature. In their liquid form many VOCs can contaminate ground water. Families of VOCs …

Flüchtige organische Verbindungen – Wikipedia

Flüchtige organische Verbindungen (englisch volatile organic compounds, kurz VOC) ist die Sammelbezeichnung für organische, also kohlenstoffhaltige Stoffe, die bei Raumtemperatur oder höheren Temperaturen durch Verdampfen (umgangssprachlich „Verdunsten“) in die Gasphase übergehen, also flüchtig sind. Das Gas Methan, CH 4, ist oft nicht eingeschlossen, manchmal explizit …

CO2 Sensors vs. VOC Sensors for IAQ - What's the Difference? …

Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants. This makes air quality sensors a better solution in applications where unusual, non-occupant-related …
