The direct quantification by glow discharge mass spectrometry with the universal relative sensitivity factors without matrix-matched standards

Analytical Methodologies for Agrometallomics: A Critical Review

“…On the basis of the mass analyzer, ICP-MS is commonly classified into inductively coupled plasma-quadrupole-mass spectrometry (ICP-Q-MS) or tandem quadrupole-mass spectrometry (ICP-Q-MS/MS or ICP-QQQ), inductively coupled plasma-time-of-flight-mass spectrometry (ICP-TOF-MS), inductively coupled plasmasector field-mass spectrometry (ICP-SF-MS), and multicollector-inductively coupled plasma-mass spectrometry (MC-ICP-MS). 14 Among them, Q-MS only fulfils sequential elements and isotope analyses, for example, Al, B, Cu, Fe, Mn, Na, 137 Ba/ 138 Ba, 79 Br/ 81 Br, 52 Cr/ 53 Cr, 58 Ni/ 60 Ni, 85 Rb, 86 Sr/ 88 Sr, 46 Ti/ 47 Ti/ 48 Ti, 64 Zn/ 66 Zn/ 68 Zn in tea samples were detected by ICP-Q-MS as characteristic elements for food traceability. 15 ICP-QQQ with tandem quadrupole mass spectrometer design is famous for high sensitivity, very low detection limits (LOD, lowest to the pg/L level), and favorable anti-interference capacity and has been applied to ultratrace metals or nonmetallic elements, such as sulfur analysis in complicated agricultural matrixes such as food, soil, plant, cell, and even seawater.…”

“…45 Nevertheless, the biggest problem GD-MS still suffers from is the accurate quantification for elements, in spite of the utilization of relative sensitivity factors and matrix-matched standards. 46 Even so, GD-MS displays versatility, e.g., pulsed GD-TOF-MS was reported to analyze elemental oxidation states from the solid material, 47,48 and GD-MS/MS to analyze pesticide in food sample. 49 Hence, GD-MS owns a potential of elemental state and organic composition analysis in the agrometallome.…”

“…After pressing the powder into an aluminum tablet, pulsed GD-TOF-MS allowed the detection of As, B, Ce, Co, Dy, Fe, K, La, Lu, Mg, Mn, Na, Nb, Nd, P, Pr, Rb, S, Sb, Si, Sm, Th, Ti, and U in ore sample .

Determination Of Elemental Impurities In Iron-Nickel-Based Superalloys By Glow Discharge Mass Spectrometry

“…[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. [28][29] X. Yu [21][22] and K. Su 23 have done some work on the determination of trace elements in superalloys by glow discharge mass spectrometry.…”

Weighting Ratio Correction Method For Depth Profiling Using Microsecond Pulsed Glow Discharge Mass Spectrometry

“…Under an identical condition of the same instrument, variations in the sputtering rates of different metals occur in GDMS. 28,29 It tends to yield divergent results concerning film thickness. To address this issue, many scholars have conducted related researches.…”
