PPM is a unit of measurement that describes the concentration of one part of a substance in a million parts of the whole.
Parts Per Million (PPM) is used in manufacturing to denote the concentration of a contaminant or ingredient within a material or process. For example, in the context of manufacturing, PPM is crucial for monitoring pollutants in emissions or impurities in raw materials to ensure compliance with safety or quality standards. Understanding and controlling PPM levels can improve product quality and reduce environmental impact.
A manufacturing facility measures the PPM of sulfur compounds in its emissions to comply with environmental regulations.
Used in environmental compliance to ensure emissions are within legal limits.
A semiconductor manufacturer controls the PPM of trace metals in silicon wafers to prevent defects in microchips.
Applied in quality control to maintain high yields and prevent defects in microelectronics production.
