Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

On a periodic chart of the elements, molar mass (M), also called atomic weight, is often listed as though it were a dimensionless quantityFig. . In reality, atomic weight is the mass of 1 mol of the element. For example, the atomic weight of nitrogen Mnitrogen14.0067. We interpret this as 14.0067 g/mol of elemental nitrogen, or in the = English system, 14.0067 lbm/lbmol of elemental nitrogen. What are the primary dim ensions of atomic weight?
