Study on the effect of polyhydroxy compounds on the sensitivity enhancement of elements in electrothermal vaporization inductively coupled plasma mass spectrometry

Separate vaporisation of boric acid and inorganic boron from tungsten sample cuvette–tungsten boat furnace followed by the detection of boron species by inductively coupled plasma mass spectrometry and atomic emission spectrometry (ICP-MS and ICP-AES)

“…2). This is because TMAH was sufficiently basic to form the borate salt, presumably TMA·B(OH) 4 , and the product was stable enough thermally to remain in the furnace prior to the vaporisation at 800 • C. The non-volatile boron were not vaporised at the vaporisa- tion temperature of 800 • C. When no modifier was added, no signal attributed to volatile boron was observed, because these boron species were almost lost, even at a drying temperature. …”

“…Then, the temperature was taken up to 800 • C for vaporisation. The generated analyte vapor, mainly tetramethylammonium borate (TMA·B(OH) 4 ), was transported into the ICP through the PTFE tube by the carrier gas. The transient signal of the 10 B + ion was integrated and the peak area was estimated.…”

“…In the commonly used ETV procedure, chemical modification techniques have been applied. For the vaporisation of B, a mannitolassisted ETV-ICP-MS was proposed [3][4][5]. NH 4 F was also effective to retain boron species [6].…”

Low-temperature electrothermal vaporization of thenoyltrifluoroacetone complex of Sc(III) and Y(III) for sample introduction in an inductively coupled plasma atomic emission spectrometry, and their determination in biological samples

“…Some other organic chemical modifiers, such as EDTA, organic acids and polyhydroxy compounds have also been reported for ETV-ICP-MS determination of some metal elements [19,20]in some standard materials. As we can see, the successful application of 8-hydroxyquinoline, PMBP, AcAc, EDTA, organic acids and polyhydroxy compounds as chemical modifiers in low temperature ETV-ICP-AES/MS indicates that the research and exploitation of organic chelating reagents as chemical modifiers have prospective potential.…”

Ultratrace determination of Pb, Se and As in wine samples by electrothermal vaporization inductively coupled plasma mass spectrometry

“…Several authors 29 have pointed out that trace element composition allows the deter-30 mination of wine origin since the mineral composition of wine is 31 related to sample provenance [3,5]. As a consequence, elemental 32 pattern composition of wine can be used as a tool to prevent adul-33 teration and fraud.…”
