ATOMIC ABSORPTION SPECTROSCOPY/ INDUCTIVELY COUPLED PLASMA – MASS SPECTROSCOPY
Identify the heavy metals present in the complex matrix by Atomic Absorption spectroscopy. The results explain the level of toxic metals present in the samples. Textile materials, plant powders, alloys, environmental samples etc, are detected for their presence up to ppt level.
UV-VIS works on the basis of absorption and transmittance. By this technique, we can analyze the samples through the spectrum obtained and qualitative / quantitative results can be evaluated.
In the Infra Red spectroscopy IR radiation passes through the substance, some wavelength of the radiation absorbed/ transmitted by the substance depending on the spectra derived. The resulting spectrum represents the molecular absorption/transmission, creating a molecular finger print of the sample. This makes IR spectroscopy useful for several types of analysis.
DIFFERENTIAL SCANNING CALORIMETRY
DSC is an instrument, which analyses the thermal properties like glass transition, crystallinity, melting point of the matrix. It is very much useful to the polymer researchers. The results interpret the property of polymer and synthetic fibres.
HIGH PERFORMANCE LIQUID CHROMATOGRAPHY - MASS SPECTROSCOPY
HPLC is specially made for separating the analytes by liquid-liquid separation. In this technique, the analytes are presented in liquid form, and the mobile phase is also a liquid, neither be isocratic or gradient type. The stationary phase is a packed column and it varies based on the application. This equipment is very much suitable for quantification upto nanogram level.
Gas chromatography specifically gas-liquid chromatography involves a sample being injected and vaporised on to the head of the chromatographic column. The sample is transported through the column by the flow of insert, gaseous mobile phase. The analytes are eluted at a particular temperature. The eluted analytes are analysed by mass spectroscopy and combined with the in-built library. Plant, environmental, microbial extracts can be analysed for unknown compounds.
