Photoionization detectors are calibrated using isobutylene, but PID is a broadband VOC detection technique, with a sensitivity that differs for each VOC. If you know what VOC you are detecting, then the table below will allow you to calculate the concentration for your specific VOC. Remember, these are approximate values, so for best accuracy you should calibrate with the relevant VOC. Multiply the indicated concentration by the appropriate Relative Response value to provide an estimate of actual VOC concentration. Download a PDF of PID Response Chart
