Instruments Discriptions
CHNS Analyzer
Make- Euro EA
Model No :- EA-3000
Application Application- As the name implies, a CHN Analyzer is a scientific instrument which can determine the elemental concentrations in a given sample. It is used to measure Carbon (C), Hydrogen (H) and Nitrogen (N). Sample sizs may differ depending on system, but most often in around a few mg. For some sample matrices larger mass is preferred due to sample inhomogenicity. This instrument uses combustion to oxidize the sample into simple compounds which are then detected with thermal conductivity detection or infrared spectroscopy. Separation of interferences is done by chemical reagents.
Nikon Microscop with Camra
Make- Nikon
Model No :- DS-Fi2
Application
K-Jeldal
Make-Pelican
Model No :- Kelvac
Application itrogen is a necessary component of all living things. Amino acids are the building blocks of proteins. When Amino acid was discovered it was found that each amino acid contained Nitrogen. Fertilizers which have Ammonia and Urea as key components are found to contain Nitrogen. Nitrogen components like TNT, Nitrocellulose etc. are key compounds in Explosives. Heterocyclic Nitrogen Compounds are important in production of Plastic, Rubber and Paint. The purity of water is evaluated in knowing the Nitrogen content of water. Nitrogen has proved to be an excellent indicator.
Gas chromatography
Make- Agilent
Model No :- 7890
Application The principle in gas chromatography principle involves separation of components of the sample under test due to partition in between gaseous mobile phase and stationary liquid phase. The components partitioned into gas come out first while other come later.Gas chromatography runs on the principle of partition chromatography for separation of components. In terms of stationary and mobile phases it is categorized under gas-liquid type of chromatography i.e stationary phase is a liquid layer supported over a stationary phase while the mobile phase is an inert and stable gas. Hence the perfect name as Gas Liquid chromatography (GLC).
GCMS (Gas Chromatogram – mass spectrophotometer)
Make-Agilent
Model No :- 7980 – 5975C
Application The Gas Chromatography/Mass Spectrometry (GC/MS) instrument separates chemical mixtures (the GC component) and identifies the components at a molecular level (the MS component). It is one of the most accurate tools for analyzing environmental samples. The GC works on the principle that a mixture will separate into individual substances when heated. The heated gases are carried through a column with an inert gas (such as helium). As the separated substances emerge from the column opening, they flow into the MS. Mass spectrometry identifies compounds by the mass of the analyte molecule. A ÒlibraryÓ of known mass spectra, covering several thousand compounds, is stored on a computer. Mass spectrometry is considered the only definitive analytical detector.
