There is a background behind it. Basically, you titrate hard water with ethylenediamminetetraacetate (EDTA) and the moles of EDTA consumed are assumed to be consumed by Ca2+ ions only. Calculate mass errors (in ppm) and m/z values based upon molecular formula. Department of Chemistry, University of Warwick, Gibbet Hill, Coventry, CV4 7AL.

Visit to know long meaning of PPM acronym and abbreviations. It is one of the best place for finding expanded names. PPM and PPB are units used in atmospheric chemistry to describe the concentration of gases. PPM stands for parts of gas per million parts of air, and PPB is parts per billion. If that's not easy to imagine, try these examples: Part per million (ppm): 1 second in just under 2 weeks. 1 litre of water in a swimming pool. Part per billion (ppb): Expressing the hardness of water by ppm CaCO3 is nothing but a conventional convenience in water industry.
