“…This approach can effectively correct system errors during sample pretreatment, ionization efficiency, and separation; thus, it can improve accuracy, precision, and reproducibility [ 26 , 27 ]. The method is widely used in the detection and analysis of pesticide residues [ 28 , 29 , 30 ], veterinary drug residues [ 31 ], natural toxins [ 32 , 33 , 34 , 35 ], heavy metal pollution [ 36 ], micronutrients [ 37 , 38 ], and vitamins [ 39 , 40 , 41 ]. However, the main factors restricting its development are the scarcity of isotope-labeled reagents and their high price.…”

The simultaneous quantification of trace and micro metabolites is a bottleneck in food and biological analysis. Phenolic compounds are the most widely distributed and have various physiological functions. In this study, the strategy for the simultaneous liquid chromatography tandem-mass spectrometry (LC-MS/MS) quantification of 13 trace and micro phenolic compounds was proposed by taking product ions and isotopic ions as quantitative ions. The method validation results showed that the limits of detection (LODs) were from 0.01 to 9.84 μg/kg, and the limits of quantification (LOQs) were from 0.03 to 32.8 μg/kg. The intra-day precision and inter-day precision were below 8.4% and 14.4%, respectively. The recoveries ranged from 81.9% to 117.2%, and the matrix effects ranged from −11.5% to 13.7%, which indicated that the method has high sensitivity and suitable stability. The developed analytical method was applied to determine trace and micro constituents in rapeseed samples. The analysis results indicated that the contents of sinapine have significantly different between high and low total phenolic content rapeseeds. This method provides a reference strategy for the simultaneous quantitative analysis of other micro- and trace antioxidants.

“…Wada et al . (2018) reported the sensitive and accurate determination of sulfur at the ultra‐trace level in high‐purity metals by ID‐SF‐ICP‐MS operated at medium resolution. Sulfur was successfully separated from the metal matrix using an alumina column, and sulfur was completely oxidised into sulfate by HClO 4 to guarantee the complete recovery of the sulfur.…”

“…Yang and Jiang (2004) demonstrated that dynamic reaction cell (DRC)-coupled Q-ICP-MS can obviate the polyatomic and isobaric interferences at m/z 32 by detecting 32 S 16 O, which is formed by the reaction of 32 S + with O 2 in the cell. SF-ICP-MS has the outstanding advantages of high sensitivity and a low detection limit and has been widely used for the determination of sulfur in various matrices (Amais et al 2014b, Lu et al 2019, Makishima and Nakamura 2001, Wada et al 2018, Wang and Becker 2014.

In this study, a rapid method for the quantification of sulfur mass fractions in geological materials using high‐resolution sector field‐inductively coupled plasma‐mass spectrometry (SF‐ICP‐MS) was developed. The effects of HNO3, Lefort, aqua regia, and HCl on the recoveries of sulfur in three different geological samples were evaluated. It was found that 0.5‐1 h digestion at 90 °C was enough to completely recover sulfur from BCR‐2 (basalt rock), GSS‐25 (loess), and GSD‐7 (stream sediment) using 2 ml aqua regia in both closed and open vessels. Compared with that of traditional digestion methods (e.g., HF‐HBr‐HNO3 acid digestion method), the efficiency of this proposed aqua regia digestion is improved by a factor of approximately 20. No loss of sulfur was observed because sulfur released from geological materials is directly oxidised to sulfate, which inhibits the volatilisation of sulfur. In addition, the effect of the heating‐condensing system combined with two different skimmer cones on the analytical sensitivity of sulfur was investigated. Compared with that of the normal sampling mode, the signal intensity of sulfur is enhanced by a factor of approximately 22 and 10 at a temperature of 140 °C using the S + X cone combination and S + H cone combination, respectively. This improvement is of importance for the determination of sulfur in samples with low sulfur content. The developed method was successfully applied to the determination of sulfur in geological reference materials. Most of the measured sulfur values of sixty geological materials, using both closed and open vessel digestion, are in good agreement with reference values. Compared with closed vessel digestion, the more flexible open vessel acid digestion is simple, fast, and shows great potential for the rapid quantification of sulfur in a large batch of geological and environmental samples.
