PID Response Factors for VOCs

Transcription

1 Indoor Air Quality PID s for VOCs Application Note TSI-148 TSI Volatile Organic Compound (VOC) probes are calibrated using isobutylene, but the sensor s Photo Ionization Detectors (PID) are broadband VOC detectors with a sensitivity that differs for each VOC compound. If you know what VOC you are measuring, then the table below will allow you to calculate the concentration for your specific VOC. These are approximate values, so for best accuracy, you should calibrate with the relevant VOC. The table includes eight columns: 1. Gas/ VOC The most common name for the VOC. 2. CAS No. You can find the VOC using the CAS No.: ask your supplier. 3. Formula To assist in identifying the VOC and to determine the VOC s molecular weight. 4. (RF). Multiply the displayed concentration by the to calculate the actual concentration of the VOC. 5. response (%) This is the inverse of the correction factor, specifying the percent response of the VOC, relative to isobutylene. If less than 100%, then the VOC is less responsive than isobutylene; if the relative sensitivity is greater than 100%, then the VOC is more responsive than isobutylene. sensitivity (%) is specified the same way as cross-sensitivity for toxic gas sensors. 6. Minimum Detection Level () PPM Also called Minimum Detectable Quantity (MDQ). Typical lowest concentration that can be detected. The in this column is for use with the PPB sensor. Since the PPB sensor has greater sensitivity than the PPM sensor, the for the PPB sensor will be much less than the for the PPM sensor. 7. Minimum Detection Level () PPB Also called Minimum Detectable Quantity (MDQ). Typical lowest concentration that can be detected. The in this column is for use with the PPM sensor. Since the PPM sensor has less sensitivity than the PPM sensor, the for the PPM sensor will be much more than the for the PPB sensor. 8.. The molecular weight of the VOC is used to convert its number concentration (PPM or PPB) to mass concentration (mg/m 3 ). The / CF/ RF is measured in dry air; high humidity will reduce this factor by 30% to 50%, so the CF/ RF should be increased in high humidity conditions.

2 VOC PID sensors cannot measure all VOCs or gases. Two types of VOCs are not measured: ZR NV No response. The 10.6 ev lamp does not ionize the VOC and the VOC cannot be measured. The vapor pressure of the VOC at 20 C is less than a few ppm. This Semi-Volatile Organic Compound (SVOC) cannot be measured. Occasionally you will be measuring a mixture of VOCs. If the total concentration is within the linear range of your PID, then it is reasonable to assume that the concentrations are additive without interference between the different VOCs. If you are measuring a combination of VOCs, then accurate measurement of one of these VOCs will be difficult. Without careful data analysis, you will get only a CF averaged measurement. Be cautious when reporting actual VOC concentration if you know that there may be several VOC s present. Balance Gas The relative response is measured in laboratory air, with 20.9% oxygen, balance nitrogen. Some gases absorb UV light without causing any PID response (e.g., methane, ethane). In ambient atmospheres where these gases are present, the measured concentration of target gas will be less than is actually present. Methane absorbs UV strongly, so for accurate measurements in methane containing atmospheres, calibrate with a calibration gas containing the expected methane concentration. 50% LEL methane reduces the reading by up to 50%. Gases such as nitrogen and helium do not absorb UV and do not affect the relative response. The correction factor for a gas mix containing PID detectable gases A, B, C with response factors RF (A), RF (B), RF(C), in relative proportions a: b: c is given by: 1 RFMix = a + b + c +... RF RF RF a b c Conversion to Mass Concentration TSI s Model 9565 VELOCICALC meter and Model 7575 Q-TRAK monitor can convert their ppm or ppb readings to mass concentration units of mg/m 3. Refer to the user instructions on how to change units of measurement and to calculate mass concentration. Accuracy of the Table This table is for indication only. Table accuracy is 1 to 2 digits only, so when calculating concentration for a specific VOC, specify to 1 or 2 digits only. For best accuracy, calibrate using the specific VOC.
