sight Spectrometry
Procedure of Mass Spectrometry: Mass spectrometry is a technique that measures the charged to passel proportion of charged particles. Its used for finding battaliones of particles, determining the primary composition of a molecule, and also for elucidating the chemic structures of molecules like aspeptides and separate chemical compounds. Mass Spectrometry works by ionizing chemical compounds to generate charged molecules or molecule fragments and measuring their mass to charge ratios. To measure the characteristics of individual molecules, a mass mass spectrometer converts them to ions so that they can be moved about and manipulated by external electric and magnetic fields. The three functions of a mass spectrometer be:
1.   A small sample is ionised sometimes to cations by loss of an electron.
2.   The ions are sorted and confused according to their mass and charge.  
3.   The separated ions are then measured, and the results are displayed on a chart.   

Real World Application: environmental scientists use mass spectrometry to detect toxins in contaminated fish. They also use it to measure the amount and nature of airborne particles in the atmosphere, data that can be used to monitor climate change.





Liquid Chromatography
Procedure of Liquid Chromatography: Liquid chromatography is an analytical chromatographic technique that is used for separating ions or molecules that are fade away in a solvent. If the solution is in contact with a second solid or liquid phase, the different solutes willing interact with the new(prenominal) phase to differing degrees due to differences in adsorption, ion-exchange, partitioning, or size. These differences allow the mixture components to be separated from each other by using these differences to determine the transit time of the solutes with a column. Liquid chromatography consists of a column with a fritted commode that holds a stationary phase in equilibrium...If you want to scramble a full essay, order it on our website: Orderessay
