PID sensor and correction factors tables

The following chart details approximate correction factors (or response factors) for specific concentrations of VOCs.

It is recommended, for best test results, to calibrate the PID sensor with the relevant VOC you intend to measure. If this is not possible, the factors listed in the table, provided by Ion Science, can be used when calibrating the PID sensor.

 NOTE : These are approximate values; so, for best accuracy you should calibrate with the relevant

VOC. (Please refer to Ion Science for details on linear range accuracy and table explanation.)

 The table includes six columns

1.

Gas/ VOC : The most common name for the VOC. If you cannot find the name of your VOC of concern, refer to Ion Science’s website.

2.

Formula : To further assist in identifying the VOC, this also is helpful in identifying its molecular weight, from which ppm measurements can be converted to say, mg/m 3 measurements.

3.

Response Factor : (RF) also known as correction factor . Multiply the output response from the cell by the RF to provide a normalized scale of VOC concentration.

4.

Relative sensitivity : (%) 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. Relative sensitivity (%) is specified the same way as cross-sensitivity for toxic gas sensors.

5.

Typical Minimum Detection Level (MDL) or Minimum Detectable Quantity (MDQ) : Typical lowest concentration that can be detected. The Mini PID HI has greater sensitivity than the Mini

PID LO, so MDL’s for the Mini PID HI are much lower. The RF is measured in dry air; high humidity will reduce this factor by 10% to 20%, so the RF should be increased in high humidity’s.

Attention : In the table below, a Correction factor listed as “NR” indicates no response since not all

VOCs or gases can be measured with a PID sensor.

 NOTE : The “Typical minimum detection level” is listed in parts per billion in the table below.

The EVM calculates VOCs in parts per million or parts per billion.
