After merger of Indian reference material activity with analytical chemistry, a new activity “Chemical Metrology” has been formed with a focus on Metrology in Chemistry (MiC) for providing traceability in chemical measurements by NPLI by doing R&D in various areas in a well coordinated network mode involving many CSIR and other institutes. It envisages participating in consultative committee on quantity of matter (CCQM)/ Asia pacific metrology program (APMP) and other
international comparisons, includes preparation & dissemination of certified reference material (CRM), proficiency testing programme with national accreditation board for testing & calibration laboratories (NABL) accredited laboratories to provide traceability in chemical measurements in the country. The materials characterization for chemical purity/ impurity and composition is the ongoing service given for in-house, public & private sector and for societal needs.

Ministry of environment & forests national communication (NATCOM) projects work started for second national communication for quality assurance for all its national teams. Ongoing project studies in SEI-Swedish sponsored project related to physico-chemical characterization of dry & wet precipitation, apart from Asia pacific network (APN) on global change-health project work, continued including scientific & technical support to our collaborators. Proficiency testing (PT) Phase-I project (code PT-44) for NABL in chemical discipline has been completed for the NABL accredited laboratories. During this period, three new CRMs [BND 3404.01 and 3405.01 for plain carbon steel and BND 3301.01 for - Alumina internal standard] were released on 5th November 2007 by Mr Ajay
Shankar, Secretary, Department of Industrial Policy and Promotion, Ministry of Commerce and industry, Government of India and Mr. Sunil Kant Munjal, Chairman, Hero Corporate Services Ltd, in the 10th Asian Symposium on Precision Forging at India Habitat Centre, New Delhi (Fig. 5.1). Participated in CCQM-P96/ APMP.QM-P11 (Arsenic content in marine swordfish); CCQM-P97/ APMP.QM-P10 (Cadmium and Lead in Herb) (Fig. 5.2); and Interlaboratory comparison for artificial rainwater under 10th 2007(Wet) EANET (Acid Deposition Monitoring Network in East Asia).
