Analytical Facility: Analytical Chemistry Section
With the development of science and technology, spectacular advancement has been made in the production of newer glasses and ceramics. Now-a-days quality demands for industrial glass and ceramic materials are steadily increasing. Therefore, the methods of quality control must be developed which are as exact as possible at the low expense of time. In Analytical Chemistry section, a constant effort is being made for the development of newer analytical techniques for the rapid and accurate determination of major, minor and trace elements present glass and ceramic materials.
In the years past, elemental determination at the major, minor and trace level was performed by classical gravimetric, titrimetric and spectrophotometric methods in Analytical Chemistry section. During 90?s most of the classical approaches have been replaced by instrumental techniques like Inductively Coupled Plasma Atomic Emission Spectrometry (ICP AES) and Atomic Absorption Spectrometry (AAS).
Although the instruments like ICP and AAS are sensitive enough but direct application of these determination techniques are, however, frequently impossible and difficult when the concentration of the desired trace elements are below the relative detection limit and also very often they differ from serious interferences caused by the high matrix concentrations. To overcome this problem, a novel separation technique has been developed in this section using solid solvent polyurethane foam (PUF) for pre-concentration or enrichment of trace/ultra-trace elements prior to their determination by instrumental techniques.
Analytical Chemistry section is engaged in the research work for the removal of toxic elements like arsenic, mercury, fluorine, lead, cadmium etc. present in water and other environmental samples.
R&D support team of the section comprise of two (2) Scientists, seven (07) Technical Officers, three (03) Technical Assistants and two (02) Technicians.
