ANALYTICAL FACILITIES

Competitive nature of the global economy has forced industry and technical establishments to constantly improve on the quality of their products. Keeping in view the stringent standards of quality prescribed for industrial products, it has become imperative to identify and quantify the samples for maintaining quality and standards of materials and finished products. For this purpose the importance of highly sophisticated analytical facilities can hardly be over emphasized.

PINSTECH has a variety of analytical equipment with advanced and powerful instrument with advanced and powerful instrumental techniques, which can be compared, to the most modern laboratories in the developed countries. Separation and pre-concentration procedures have been developed for a variety of elements based on their solvent extraction, ion exchange and adsorption studies with wide applications in radiochemistry and in waste management technologies. Services include the analysis of biological, environmental, geological and industrial samples, alloys, reactor grade water samples, etc.

Trace element analyses of industrial as well as environmental materials are carries out using inductively coupled Plasma-Optical Emission spectrometer (ICP-OES).  The equipment has 27 MHz radio frequency source, two high resolutions thermostated vacuum spectrometers, one monochromator and 42-channel polychromator, and it is equipped with a medium spark source for direct analysis of metals and alloys. Being cost-effective and efficient technique for elemental analysis of inorganic materials, it is a highly useful tool for metallurgical industry.  

Atomic Absorption spectrometry is used for quantitative analysis of metals at trace and ultratrace levels. If can be applied to a wide range of matrices like biological, geological, agricultural and metallurgical samples.  

To cater for the specialized needs of industry, elemental analysis such as carbon and boron analysis, and a simultaneous analysis boron analysis, and a simultaneous analysis of 49 elements in metals, alloys and powders can be performed with precision.

Atomic Absorption Spectrophotometer

 

A gas analysis facility is also available to determine the content of hydrogen, nitrogen and oxygen in metals and alloys with detection range down to ppm level and accuracy of 1%. Elemental analysis can also be performed on other substances, which include ores, gemstones, foodstuffs, fertilizers, insecticides, agricultural products, pharmaceuticals, water, polyaromatic carbons, steroids, and fuels (solid and liquid).

The Neutron Activation Analysis, a nuclear reactor based technique, is a very sensitive and precise multi-elemental analysis method that has established its applicability for trace element analysis of a wide spectrum of matrices including forensic, archaeological and environmental studies and materials characterization.  

Multichannel Analyser Set UP

Atomic Emission Spectrometry is a multi-elemental and rapid analytical tool, which can handle the samples in the form of sold powder, metallic chips, alloys and liquids. If can be applied to biological, agricultural and metallurgical materials.  

 Atomic Emission Spectrograph

Electroanalytical techniques are sensitive and low cost methods for the determination of trace metal impurities, anions, cations, toxic compounds and gases.  

Gas chromatography is used for the analysis of gases and organic constituents such as CO, SO2 and various pesticides. Liquid Chromatography is used for the analysis of anions and cations in water samples at trace level and also for the analysis of organic compounds such as steroids, and polyaromatic hydrocarbons. 

The alpha spectrometric system can be used for the determination of actinides in food and environmental samples as well as for the determination of radio nuclide upto pico curie levels. 

Gas Chromatograph

 

X-ray Fluorescence Spectrometry is a multi-element, simultaneous and non-destructive technique having potential of analyzing more than 40 elements in various solid matrices ranging from 100 ppm to percentage levels.  

A point to point elemental analysis of metals can also be performed using Scanning Electron Microscope. The Transmission Mossbauer spectroscopy facility at PINSTECH is capable of handling the characterization for iron containing materials.  

X-ray Fluorescence Spectrometer

Mass Spectrometry playing an important role in R&D work and services analysis in the fields of agriculture, hydrology, geology, environment and medicine. The isotopic ratios of several elements are currently being determined. These include, 2H/1H, 13C/12C, 15N/14N,18O/16O and 34S/32S.These ratios are being used in nitrogen fertilizer uptake studies, quantification of biological studies. In addition to the above-mentioned isotopic ratios, mass spectrometers are capable of covering a range of 2 to 300 atomic mass units (amu). Liquid scintillation spectrometers for measuring tritium and radiocarbon of water samples for hydrological studies and ultraviolet/Visible (UV/VIS) Spectrometers for the determination of the purity of various ligands, radioactive products and Tc-kits, etc., are other analytical facilities available at PINSTECH. These facilities are internationally rated as one of the most efficient and capable analytical facilities in the region.
