The quantification of a variety of elements in the field of ICP-MS is restricted by isobaric interferences. The recent development of ICP-MS/MS (triple quadrupole configuration) offers a new way to solve the problem of the detection of such elements affected by interferences because the signal caused by either the analyte or the isobaric interference can be shifted to another m/z through reactions with the cell gas (oxygen, ammonia or hydrogen). This system consists of two quadrupoles (Q1 and Q2) with a collision/reaction cell in between. When using the MS/MS mode of this configuration it becomes possible to restrict the ions entering the cell to a defined m/z and therefore get a better insight into the reactions possibly occurring within the collision/reaction cell. While using oxygen as a cell gas analyte ions can undergo oxygen transfer as well as asymmetric charge transfer reactions. As a proof for the latter reaction two types of measurements have been carried out, using both oxygen with natural isotopic composition and isotopically enriched oxygen (97% O-18(2)) as cell gases.

Managing transition metal interferences during chemical vapor generation using the hydrolysis products of tetrahydridoborate: a proof-of-concept study

Michelle Buoso, Beatrice Campanella, Massimo Onor, Emanuela Pitzalis, Alessandro D'Ulivo

Summary: The use of BH intermediates as derivatization reagents significantly improves the tolerance to interference from transition metal ions in the generation of SbH3 and BiH3, and shows high tolerance in a wide range of acidity. The method has been successfully applied to the determination of Sb and Bi in complex samples, providing further understanding of the chemical behavior of borohydrides.

A low-cost and high precision determination method of 87Sr/86Sr ratios for red wine using thermal ionization mass spectrometry without column separation

Chao-Feng Li, Xuan-Ce Wang, Zhu-Yin Chu, Peng Peng

Summary: Thermal ionization mass spectrometry (TIMS) is the standard method for obtaining precise Sr-87/Sr-86 isotopic ratios. However, our developed hydrofluoric acid coprecipitation method offers a low-cost, rapid, simple, and high-throughput alternative for analyzing red wine samples, effectively eliminating isobaric interference and matrix element inhibition.

Spatio-temporal dynamics of a microsecond pulsed Grimm-type glow discharge

Ivan B. Krstic, Bratislav M. Obradovic, Milorad M. Kuraica

Summary: This paper presents the spatio-temporal dynamics of a Grimm-type microsecond pulsed glow discharge (mu PGD) in argon at 6 mbar. The occurrence of a high current peak during the discharge ignition is analyzed and the importance of displacement current is emphasized. The development of electron excitation temperature for argon atoms and ions at various distances from the cathode is measured. The spatio-temporal evolution of selected spectral lines of argon and copper atoms and ions is analyzed during different phases of the discharge. The results suggest that the behavior of spectral line emissions differs between the pre-peak and afterglow periods, with different lines reaching maximum intensity during these phases. The appearance time and decay time of the afterpeak are shorter for ions than for atoms. These findings are explained in terms of three-body recombination processes and ion mobilities.

Sensitivity improvement of laser-induced breakdown spectroscopy to detect heavy metals in water by Tesla coil discharge

Qiuyun Wang, Anmin Chen, Xun Gao

Summary: In this paper, the combination of Tesla coil discharge (TCD) and laser-induced breakdown spectroscopy (LIBS) was used to enhance the emission of Al atomic lines and AlO molecular bands. The optimized distance between the TCD tip and the sample surface was found to be 5 mm, and the optimal laser energy was 25.1 mJ. Furthermore, TCD-SELIBS showed lower limits of detection (LoDs) for Cr and Pb elements compared to surface enhanced LIBS (SELIBS). The combination of TCD and LIBS is a promising technology for high-sensitivity analysis of heavy metals in water, with the advantages of simplicity, low cost, ease of operation, industrialization, and commercialization.

A new appraisal of ilmenite U-Pb dating method by LA-SF-ICP-MS

Yanwen Tang, Tingguang Lan, Jianfeng Gao, Zhongjie Bai, Xiaowen Huang, Junjie Han, Na Liu

Summary: Titanium is an important metal widely used in various industries. Ilmenite minerals are the main source of titanium metal and can be found in igneous and metamorphic rocks as well as different types of deposits. To accurately determine U-Pb ages of ilmenite, a new calibration method and appropriate reference materials are urgently needed. Laser ablation sector field inductively coupled plasma mass spectrometry has been used to minimize matrix effects and zircon 91500 has been identified as a suitable reference material for measuring the Pb/U ratio in ilmenite. The direct calibration method using zircon 91500 as an external standard has been found to be effective for in situ U-Pb dating of ilmenite samples under different ablation settings.
