Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc. Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution. ppm is defined as ppm = 1,000,000 c / s = 106 c / s (1) 2013-05-22 The difference of a 300 MHz and 900 MHz NMR is the relationship of the ppm to Hz. For 300 MHz instrument, 1 ppm is equal to 300 Hz and for a 900 MHz instrument, it corresponds to 900 Hz. 2021-04-15 Just as per cent means out of a hundred, so parts per million or ppm means out of a million.
