“…In a similar experiment, elements in nickel super-alloys were determined by GD-MS with the relative sensitivity factors generated from certified iron matrix reference materials. 53 Concentration values from GD-MS were in agreement from values obtained by wet chemical techniques. GD-MS was also applied to the trace element determination and depth profiling of thin copper films.…”

“…Selenium species [Se(IV) and Se(VI)] were estimated in tube-well water samples by ion chromatography coupled with ICP-MS and also by a UV-assisted vapor generation combined with a sensitive "collect and punch"-ICP-MS method. Similarly, the possibility of using moss (Funaria hygrometrica), immobilized in a polysilicate matrix as the substrate for speciation of Cr(III) and Cr(VI) in various water samples was studied by using ICP-MS. [376][377][378][379][380][381][382][383][384][385][386][387][388][389][390] The "collect and punch" cold vapor ICP-MS method was also developed for the direct determination of mercury at nanograms per liter levels. 391 An ultrasound-assisted extraction procedure for the fast estimation of major, minor and trace elements in lichen and mussel samples was developed and ICP-MS was used to estimate elements such as Na, K, Ca, Mg, Cr, Mn, Co, Ni, Cu, Zn, Ge, As, Se, Rb, Sr, Zr, Ag, Cd, In, Sb, Cs, Ba, Pb and Bi.…”

All rights reserved EUROPEAN JOURNAL OF MASS SPECTROMETRY This review highlights the research in mass spectrometry carried out all over India, with a focus on the last two decades. There has been a phenomenal increase in the use of mass spectrometers in India during the last decade following the introduction, at the beginning of the 21st century, of rugged electrospray ionization sources for the commercially available instruments, with applications such as pharmacokinetics and bio-equivalence drug studies, pesticide residue analysis and proteomics. There have been more papers published in these areas than could be fully covered in this article. This review covers mostly research in mass spectrometry carried out continuously in institutions where advanced facilities for mass spectrometry are functional. Researchers in India, with some notable exceptions, have always used and still use commercial mass spectrometers in their various areas of research, rather than develop their unique instruments. The review is divided into three parts: organic, elemental (or atomic) and biological mass spectrometry. Organic mass spectrometry Organic and bio-organic chemistry Research in organic mass spectrometry in the early years was mainly focused on the study of mass spectral fragmentation of different classes of new compounds,and was initiated in the 1960s by the late Das and his colleagues from the National Chemical Laboratory (NCL), Pune. The first double-focusing mass spectrometer (CEC-110 B) was installed at NCL for high-resolution mass measurements. The compounds studied by Das and his colleagues included aromatic amides, Benzophenanthridine derivatives, norses

“…In a search for a cost-effective alternative to HR GDMS for the analysis of superalloys used in advanced aero-engines, Shekhar et al 181 used dc GDMS with a quadrupole analyser to determine trace impurities in nickel. The RSF were determined using NIST SRM 1761 and 1762 (low steel alloys).…”
