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) are two instrumental methods of analysis and they can be linked together as GC-MS to allow substances in a sample to be separated and then identified.
 Applications of Gas chromatography and mass spectrometry:
 Chemical engineering:  GC-MS is used for the analysis of unknown organic compound mixtures.  Gas chromatography and mass spectrometry is used to determine the composition of bio-oils processed from  the raw biomass
Chemical warfare agent detection:  mass spectrometry  have been modified for field portability and near real-time detection of chemical warfare agents These complex and large GC-MS systems have been modified and configured with resistively heated low thermal mass gas chromatographs that reduce analysis time
Anti-doping analysis: GC-MS is the main tool used in sports anti-doping laboratories to test athletes for the performance-enhancing drugs
Food and perfume analysis: Foods and beverages contain numerous aromatic compounds and   some naturally raw materials during processing . It is also used to detect and measure  polluting from spoilage or adulteration which is harmful and which is often controlled by governmental agencies, for example pesticides.
Medicine: GC-MS can determine compounds in urine even in minor concentration. These compounds are normally not present but appear in individuals suffering with metabolic disorders. This is increasingly becoming a common way to diagnose.

Proteomic Experiment: Mass Spectrometry Cellular factories localize and push proteins into compartments where they perform their variety of the functions and subcellular protein provide high-end indication for its activities. Researchers can envisage protein dispersal in the cell by using Super-resolution microscopy by applying antibodies or by tagging proteins with florescent probes. Such kind of method is not innovative and researchers have to pin down their choice of proteins to a known set. Unbiased Mass Spectrometry based proteomic method present expansive way, and the credit goes to the specificity, accuracy and scale they provide. Lately researchers are using the approach to learn protein activity at the sub cellular level. The new dubbed spatial proteomic methodology, offer researchers to build a comprehensive cellular maps and show the hidden life of proteins- who they interact with, where they live & they move around- in healthy as well as in diseased cells.

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 very popular but is much more sensitive.   Electrospray ionizat

Gas chromatography and mass spectrometry- welcome news for chocolate lovers Apart from other research, gas chromatography and mass spectrometry, the heartbeat of analytical tools again proved to be bonus for the chocolate lovers. Serotonin called as mood lifter found in chocolate, which is manufactured by cocoa beans. Chocolate change the mood and is loved by every category of population. Jackfruit found in most of the tropical region which are very low cost and are now replacement for cocoa beans, which is the main constituent in chocolate. The demand of chocolate in the world is elevating day by day and beating the production of cocoa beans. The sweet smelling jackfruit are boiled, roasted and steamed prior to eating, which is the cheap source of protein, fibre, and minerals, and these are mostly thrown as waste. The analysis predicted that the demand for these beans will cross 4 million tonnes by 2020.Researchers were finding a better way to put the waste jackfruits
