mass spectrometry ms is an analytical technique that ionizes chemical species and sorts the ions based on their masstocharge ratioin simpler terms a mass spectrum measures the masses within a sample mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.

mass spectrometry important technical adjuncts in the devices heretofore described the presence of a good vacuum system has been assumed mass spectroscopy originated at about the time that high vacuum was first attained in the laboratory high vacuum refers to a pressure low enough that the mean free path the distance traveled between collisions of molecules in the residual gas is.

radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.
