What Does PPM Stand For?
PPM stands for Parts Per Million
PPM, or Parts Per Million, is a unit of measurement commonly used to express very dilute concentrations of substances. It represents the number of parts of a substance per million parts of the total solution or mixture, allowing for precise quantification of trace elements in various fields such as chemistry, environmental science, and manufacturing. PPM is particularly useful for evaluating pollutant levels, ingredient concentrations, and quality control in industrial processes.
