PPM - Parts Per Million: A Quick Overview PPM measures the concentration of a substance in a mixture, indicating how many parts exist per one million total parts. This measurement is crucial for small concentrations in various fields. Calculating PPM PPM can be calculated by volume or mass. For volume, divide the substance's volume by...

Understanding UEL - Upper Explosive Limit The Upper Explosive Limit (UEL) is the highest concentration of a gas or vapour in air that can ignite when exposed to an ignition source. Above this limit, the mixture becomes too rich in fuel to support combustion. The Importance of UEL Knowing the UEL is vital for workplace...
