SOLICITATION OF IONIZATION TECHNIQUE IN MASS SPECTROMETRY There are many ionization techniques combined with Mass spectrometry. Electron impact (EI) and Fast Atom Bombardment (FAB) are the classical ionization technique used mainly by the chemist. Now, these techniques for ionization are not generally used in modern mass spectrometry except EI for environmental work using GC-MS. Atmospheric Pressure Chemical Ionization (APCI), electrospray ionization (ESI), Matrix Assisted Laser Desorption Ionization (MALDI) are Modern Ionization techniques in mass spectrometry. APCI forms a protonated molecule and is completely compatible with Liquid Chromatography (LC) and so it is more preferred over EI methods. Electrospray Ionization Method Combined with Matrix-assisted laser desorption ionization (MALDI) has eliminated the application of FAB because it produces the protonated molecules, which made FAB v...

Mass Spectrometry: Reveal Secrets There is something unique pattern in fingerprints of an individual which constitute of valleys and ridges. Mass Spectrometry imaging of chemical compounds in fingerprints help in determination of lifestyle of an individual. Mass spectrometry imaging visualizes the spatial relationship of each compound detected, allowing ridge detail and chemical information in a single analysis. The presence of a single compound may not be sufficient to provide detailed information about an individual, but the compilation of multiple compounds present in a latent fingerprint may give insight into one’s lifestyle. Chromatography and mass spectrometry coupled methods, such as liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS), provide chemical fingerprint information, but typically require multiple fingerprints with no spatially relevant information. The multiplex method allowed MS/MS of citric acid, tartaric a...

Gas chromatography and mass spectro metry Gas chromatography-mass spectrometry is an Instrumental and analytical technique which is a combination of both mass spectrometry and chromatography which is utilized for separating, identifying and quantifying complex chemical mixture. the substrate mixture is vaporized and then the mixture is separated by gas chromatography followed by mass spectrometry where ions are produced for further separation. Ionisation Method is mainly utilized for the ions production in Gas chromatography- mass spectrometry process Gas chromatography and mass spectrometry technique is highly utilized in in Drug detection, Fire investigation and Environmental analysis. It allows the analysis and detection of tiny amounts in a substance GC-MS is used as a forensic substance which positively identifies the presence of a particular substance. Gas chromatography (GC) and mass spectrometry (MS) ar...
