Introduction: What is Mass ?
What is Mass?
A mass spectrometer is an instrument that measures the mass of microscopic particles such as molecules and atoms. We can identify a molecule and quantify the amount of target chemicals in mixtures from this information. Mass of natural materials and units of mass will be explained here.
