“…TIMS is a reference technique for actinide isotope measurement to obtain isotope ratios with high accuracy (measurement trueness and precision) [6][7][8][9]. Another advantage of TIMS analyses is the possibility to perform concentration determination by isotope dilution (ID-MS) with low uncertainty, lower than 1 % [10][11][12]. TIMS is frequently used for actinides isotope composition determination [6,7,[13][14][15][16][17][18], in particular for uranium and plutonium [4,5,8,[19][20][21][22].…”

“…Several studies for zirconium isotope measurement have been reported in literature. They are mainly two principal techniques used for this kind of measurement: multiple collector-inductively coupled plasma mass spectrometer [2][3][4]9,10] (MC-ICP-MS) and thermal ionization mass spectrometry [1,2,5,6,8,[18][19][20] (TIMS). TIMS is a reference technique for isotope measurement [21][22][23]. TIMS allows reaching isotope ratio with high measurement trueness and precision.…”

“…TIMS allows reaching isotope ratio with high measurement trueness and precision. Another advantage of the TIMS is the possibility to perform concentration determination with low uncertainty, better than 1 %, thanks to the use of isotope dilution [2,19]. One of the major difficulty of zirconium measurements by TIMS is the low ionization efficiency of zirconium due to its high ionization potential (6.84 eV) [2].…”

A new Thermal Ionization Mass Spectrometer (TIMS) analytical procedure was developed to measure with high accuracy the zirconium isotope abundance and concentration without molybdenum correction in nuclear samples. A zirconium selective separation using UTEVA column was used before the TIMS measurement in order to remove all possible isobaric interferences (Mo, Y, Nb and Ru) in the solution. The separated solution was then deposited onto a filament previously outgassed for 4 hours to reduce the molybdenum traces in the filament. Then, the filament was introduced into the TIMS source and was maintained for 4 hours at a current of 5 A (ionization filament) and 1.2 A (evaporation filament) in order to eliminate all molybdenum trace present in the filament and in the sample. This methodology allowed the zirconium isotope abundance determination without using the molybdenum interference correction equation. The analytical results obtained with a natural solution after separation is in good accordance with the reference values: bias lower than 0.16 % for the 90 Zr, 91 Zr, 92 Zr and 94 Zr isotope abundance, and a bias of ~0.8 % for the minor isotope (96 Zr) were observed. This zirconium abundance determination methodology was used on three nuclear samples. Then, the calibration of a 91 Zr spike solution was performed by reverse isotope dilution using a SPEX standard zirconium solution. The zirconium concentration determination was then performed on the three nuclear samples by isotope dilution using the SPEX standard zirconium solution and the 91 Zr spike solution. The final uncertainties were estimated to be lower than 1 %.

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
