last changed 7/2/2015

Characterisation and Measurement Lab is a Central Analytical Instruments Facility which provides specialized analytical services to the R&D projects of CECRI as well as other organizations like academic institutions and industries.Thermogravimetric Analyzer(TGA) Differential Thermal Analyzer( DTA) Elemental analyzer CHNS , High Pressure Liquid Chromatography (HPLC) Gel Permeation Chromatography(GPC) and Atomic Absorption Spectrometer(AAS) with graphite furnace atomizer attachment are available in this lab.  These analytical instruments are being extensively used to characterize the materials developed for energy and sensors applications. They are also used to analyse the organic compounds including polymers. These analytical facilities are being extended to other academic institutions and industries on payment basis. The details of charges and necessary applications are available in www.cecri.res.in . Two Scientists, three Senior Technical officers and one Senior Technician are working in this lab. One CSIR-Senior Research Fellow is working for his Ph.D degree on the topic,’ Electroanalysis of pesticides”
