Ppmv
PPMV (Parts Per Million by Volume) is a unit of measure used to denote the concentration of a substance in a solution or mixture. It is often used in the fields of chemistry, environmental science, and medicine to quantify the presence of trace amounts of substances such as pollutants or drugs.
Definition[edit | edit source]
PPMV stands for "parts per million by volume." It is a unit of concentration that describes the amount of one substance mixed into another. In the context of a gas mixture, for example, one PPMV of a certain gas means that for every million volumes of the mixture, one volume is made up of that gas.
Usage[edit | edit source]
PPMV is commonly used in environmental science and pollution studies to measure the concentration of pollutants in the air. It is also used in medicine and pharmacology to measure the concentration of drugs in a solution or the amount of a particular substance in the body.
Calculation[edit | edit source]
The calculation of PPMV depends on the nature of the substances involved. In the case of gases, it is usually calculated as the volume of the substance of interest divided by the total volume of the mixture, multiplied by one million.
