The BCSIR Laboratory Chittagong has a several mass spectrometers with a variety of ionization techniques available for molecular mass measurements of small molecules, biomolecules (e.g. proteins, polysaccharides) and nano materials (e.g. gold nano clusters). The facility offers a wide range of services, including (1) accurate mass analysis for generating precise chemical formulae and MS/MS for further structural elucidation; (2) targeted quantitative analysis by triple quad MS; (3) intact protein analysis; and (4) targeted and untargeted metabolite and small molecule screening in biological samples. We also provide method development services.
