Determination of ultratrace amounts of boron in high purity alcohols by inductively coupled plasma-mass spectrometry with hydrofluoric acid/potassium fluoride treatment

Evaluation of ammonium fluoride for quantitative microwave-assisted extraction of silicon and boron from different solid samples

“…If Si or B are the target analytes, the formation of these volatile compounds implies a high risk of analyte loss after the vessel is opened, even if the decomposition of the sample has taken place in a closed system [3,4,13]. However, this problematics is much more complex and what reaction products will be finally created is strongly dependent on the experimental conditions [36,37]. The addition of mannitol and glycerol was reported to be somewhat efficient for suppression of the volatilisation and for the stabilisation of boron; KF solution was however found to be more suitable for this purpose [37].…”

As potassium is a major element in most geological samples, only HF is needed for the stabilisation of boron in most geological sample solutions and attaining accurate analytical results [36].…”

Substoichiometric Isotope Dilution Mass Spectrometry of Boron by the Ion-Pair Extraction with Halogenated Salicyl Alcohol Derivatives and a Quaternary Ammonium Salt

“…Various analytical methods for the determination of boron, such as spectrophotometry, [2][3][4][5][6][7][8][9][10][11][12] fluorometry, 13,14 electrothermal atomic absorption spectrophotometry, 15,16 inductively coupled plasma optical emission spectrometry, 17,18 inductively coupled plasma mass spectrometry, 19,20 and neutron activation analysis, 21,22 have been used in various fields. Since these methods are based on the comparative method with calibration standards or calibration curves, they cannot escape from matrix effect caused by sample matrices.…”

Boron forms unexpected glycopeptide derivatives during MALDI‐MS experiment

“…[15] Alcohols such as 2-propanol also extract boron from borosilicate glass flasks. [16] It has been reported that boron extracted from a borosilicate glass container by methanol exists as TMB. [17] The major problem in an inductively coupled plasma mass spectrometry (ICP-MS) experiment is potential contamination from the elemental components of the glassware.…”

“…However, the use of 10-day aged ACN in a borosilicate glass bottle (same type of bottle as Bottle D in Table 1) for enriching glycopeptides or dissolving matrix molecules did not promote +8n Da signals (data not shown). Boron release from borosilicate glassware by several organic solvents has been reported, [16,17] but the amounts of boron extracted by ACN would be sufficiently low to cause +8n Da signals.…”
