PPQ stands for Parts Per Quadrillion
PPQ, or Parts Per Quadrillion, is a unit of measurement used to express extremely low concentrations of a substance within a solution or mixture. It denotes one part of a substance for every quadrillion parts of the total, equivalent to 1 part in 1,000,000,000,000,000. This metric is commonly utilized in fields such as environmental science, chemistry, and pharmaceuticals to quantify trace contaminants or elements at incredibly small concentrations.
