... The mole is defined as the amount of substance that contains as many elementary particles as there are atoms in 12g of carbon-12 The average atomic mass (AR) of an atom of carbon-12 is 1.99252 x 10-23 g. So the number of atoms in 12g of carbon-12 is given by: 12 g / 1.999252 x 10-23 g = 6.02 x 1023 ...

Gas chromatography–mass spectrometry
Gas chromatography–mass spectrometry (GC-MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples. GC-MS can also be used in airport security to detect substances in luggage or on human beings. Additionally, it can identify trace elements in materials that were previously thought to have disintegrated beyond identification.GC-MS has been widely heralded as a ""gold standard"" for forensic substance identification because it is used to perform a specific test. A specific test positively identifies the actual presence of a particular substance in a given sample. A non-specific test merely indicates that a substance falls into a category of substances. Although a non-specific test could statistically suggest the identity of the substance, this could lead to false positive identification.
