Sampling of high molecular weight hydrocarbons with adsorbent tions (ppm-ppb range) so pre-concentration of the pollutants is necessary
9 Mar 2020 You can perform a PPM calculation easily once you understand what the measure is and learn a basic formula. There are three steps: get
x (ppm) = 10000 ⋅ 1.7% = 17000ppm. Percent to ppm conversion table 20 ppm is the OSHA permissible exposure limit (PEL) (8 hour time-weighted average). 10 ppm is the REL (Recommended Exposure Limit) set by NIOSH, the US National Institute for Occupational Safety and Health. 10–20 ppm is the borderline concentration for eye irritation.

Use PPM to percent conversion calculator to convert PPM to Weight Percent. PPM refers to parts per million. It represents the part of the whole number in units of 1/1000000. It is a dimensionless quality and is equal to 1×10 -6. One parts per million (PPM) is exactly equal to 0.0001%.
