Short summary
For volatile organic compound (VOC) observations, zero gases free of VOC traces are essential for the characterisation of the measurement devices and procedures, for instrument operation as well as for calibrations. Three gas purifiers were tested for their removal efficiency of VOCs following a standardised procedure. Results show that not all purification methods removed VOCs from the zero gas and that a gas purifier needs to be tested before its intended application in the field.
