The detection limits in the Detection Limit Chart are given in "parts per million" by volume (ppm) at 20°C and 1 atmosphere of pressure. These values can be converted into the concentration unit "mg/m3" by using the equation below:

For a gas at 20°C and at 1 atmosphere of pressure:

Concentration (mg/m3)= [Concentration(ppm) * Molec. weight (g/mol)] / [24.04 l/mol]
