lowppm
Lowppm, short for low parts per million, is a term used to describe solutions with small concentrations of dissolved substances. It is a relative indicator: the lower the ppm value, the fewer dissolved solids or ions are present in the solvent. In aqueous solutions, 1 ppm is approximately 1 milligram of solute per liter of solution, though exact mass fractions depend on temperature and density.
Measurement and reporting of ppm can vary by method. Conductivity meters convert electrical conductivity to an
Typical ranges labeled as lowppm differ by context. In water treatment and purification, sub-100 ppm is often
Applications of lowppm measurements include water quality control, chemical processing, environmental monitoring, and quality assurance in
