Part per Million

ppm

Definition

Parts per million is a dimensionless unit expressing the ratio of one part solute to one million parts solution by mass. It is widely used for expressing very low concentrations in environmental and industrial applications.

History/Origin

The concept of parts per million originated in analytical chemistry as a convenient way to express very small concentrations. It became standardized in environmental regulations and industrial quality control for its simplicity and clarity.

Current Use

Universally used in environmental science, water treatment, air quality monitoring, and industrial quality control. It is the standard unit for expressing concentrations of contaminants, additives, and trace elements in various media.

Gram per Liter

g/L

Definition

The gram per liter is a commonly used unit of mass concentration, representing the mass of a solute dissolved in one liter of solution. It provides a practical measure for laboratory work and is widely used in analytical chemistry.

History/Origin

This unit emerged from the need for practical measurements in laboratory settings where gram quantities are more convenient than kilogram quantities. It became standardized as part of the metric system and is widely used in scientific research.

Current Use

Frequently employed in analytical chemistry, biochemistry, and environmental monitoring for expressing concentrations of various solutes. It is particularly useful for trace analysis and quality control in laboratory settings.
