متن کاملDetermination of sulfur in fossil fuels by isotope dilution electrothermal vaporization inductively coupled plasma mass spectrometry
The determination of S by solution nebulization quadrupole inductively coupled plasma mass spectrometry (ICP-MS) is dif®cult because of interferences from oxygen dimer ions. The large O2 z ion current from the solvent water is a serious interference at S, the most abundant of the four isotopes, and precludes its measurement. The isotopic composition of S varies in nature as a consequence of nat...
متن کاملAccurate determination of sulfur in biodiesel using Isotope Dilution-Triple Quadrupole ICP-MS (ID-ICP-QQQ)
The development of accurate, sensitive and fast analytical methods for the determination of low levels of sulfur (S) in organic matrices is important in several applications. In this note we concentrate on the determination of S in biodiesel, but the methodology is also applicable to the determination of S (plus other elements) in other matrices such as biological materials and S-containing drugs.
متن کاملDetermination of serum glucose by isotope dilution mass spectrometry: candidate definitive method.
We report a rather simple method to determine glucose concentration in serum, using isotope dilution mass spectrometry and [13C6]glucose as internal standard. The procedure involves a single step of sample purification and the conversion of the analyte into its aldononitrile pentaacetate. The between-day and within-day contribution to total variance for a single measurement was determined by as...
