“…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

“…Glow discharge mass spectrometry (GD-MS), which is an efficient direct solid analysis method, [2][3][4][5][6][7][8] has been developed rapidly since the 1980s, 9 especially in the trace analysis of high pure metal and semiconductor materials. [10][11][12][13][14][15][16][17][18][19][20] the advantages of GD-MS are its ability to determine almost all elements, superior detection limits, multi-elemental analysis, little matrix effect and wide linear dynamic range. [21][22][23] the interferences, which include isobars, multi-charge ions and multi-atom ions generated by the discharge gas, matrices and alloy elements, have a serious effect on the determination of trace elements, so the main problem is to eliminate the mass spectral interference for the determination of trace elements in the superalloy by GD-MS.…”

Mass spectral interference was investigated systematically during the determination of trace elements in superalloy by glow discharge mass spectrometry (GD-MS); moreover the main mass spectral interference and interference level of isotopes were provided in detail. According to the mass spectral interference of elements, different methods were selected for interference correction. The effects of mass spectral interference were removed efficiently by using correction methods such as selecting isotopes without interference, matching sample matrices and deducing interference with multivariable linear regression. The determination results of three superalloy samples show that trace elements such as B, Mg, Ga, As, Ag, In, Sn, Sb, Te, Tl, Pb and Bi were determined successfully after interference correction.

“…GDMS is considered to be the most effective method for the direct determination of trace and ultra-trace elements in solid conductive materials 24 and is widely used in the analysis of metals, alloys, semiconductors, etc. [25][26][27][28][29][30][31][32] In an analysis, the interference affects the accuracy of the results, so mass spectrometric interferences should be fully considered in GDMS analysis, 21-22, 27, 33-35 especially for a complex matrix. The main interferences in GDMS analysis are heterotopic interference, polyatomic ion interference and multi-charge ion interference.…”

“…When no suitable certified reference material can be found, the RSF obtained from one matrix reference material can be used to analyze another matrix sample. [25][26][27] In recent years, scholars have done more research on RSF. [36][37] However, the experimental results show that some elements in some matrices cannot provide satisfactory results after being corrected by RSF obtained from different matrix reference materials.…”
