11/06/2020· Sensor technology for online VOC assessment. Carbon dioxide is normally monitored by non-dispersive infrared spectroscopy (NDIR) sensors. The cost is low (less than € 100), and the performance of the sensor is generally good with little drift. Self-calibration can be done periodically by exposure of the sensor to outdoor air.
Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are non-selective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors …

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 ...
To make full use of the potential of low-cost sensors for ultra-low VOC concentrations, calibration is an often underestimated challenge. The more complex the expectations, , several target gases, mixtures of target gases, complex and variable background, the more complex the calibration procedure. This is due to the fact that data analysis is not based on a physical model of the sensor(s ...
Please note, this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and , AMS recommends that you run this sensor for 48 hours when you first receive it to "burn it in", and then 20 minutes in the desired mode ...
