TL;DR: The performance of laser-induced breakdown spectroscopy for quantitative analysis of wear metals in oils has been evaluated in this paper with a specific ablation configuration of a thin layer of oil covering the polished surface of a pure aluminum target.

TL;DR: A sensitive and simple method using magnetic multi-walled carbon nanotubes, as an adsorbent, has been successfully developed for extraction and preconcentration trace amounts of Se(IV) with detection by hydride generation atomic fluorescence spectrometry.

TL;DR: In this paper, a procedure is suggested to assess the quality of linear regression used for the calibration graph, based on the use of confidence limits for the concentration, as the regression coefficient is not appropriate for this purpose.

TL;DR: A simple high-performance liquid chromatographic method using fluorescence detection was developed for the determination of acyclovir in human plasma, which had a mean absolute recovery of 96%, while the within-day and between-day coefficients of variation and percentages error were all less than 8%.

TL;DR: A procedure for Stable Isotope Dilution Analysis in molecular Mass Spectrometry which does not require a methodological calibration graph and can be applied in combination with minimal labelling has been evaluated, and a full uncertainty budget determination has been developed taking into account all uncertainty sources.
Abstract: A procedure for Stable Isotope Dilution Analysis in molecular Mass Spectrometry which does not require a methodological calibration graph and can be applied in combination with minimal labelling has been evaluated. This alternative approach is based on the determination of the molar fractions for each pure isotope pattern (natural abundance or labelled) contributing to the isotope pattern observed in the mixture of natural abundance and labelled molecules by multiple linear regression. Two labelled compounds, 13C1-labelled or 13C6-labelled phenol, were compared to study the influence of the number of 13C atoms in the labelled molecule. The procedure was evaluated by comparing the results obtained for the determination of phenol in NIST 1584 CRM by GC-EI-MS using the classical isotope dilution calibration procedure and the new procedure based on multiple linear regression of isotope patterns without a calibration graph. The results obtained using the proposed procedure agreed well with both the certified values and those obtained using the classical Isotope Dilution Mass Spectrometry (IDMS) calibration procedures. For the evaluated procedure, a full uncertainty budget determination has been developed taking into account all uncertainty sources, including those derived from the uncertainties in the isotope patterns of the natural and labelled compounds. The measurements with the 13C1-labelled phenol provided lower propagated uncertainties in comparison to the use of 13C6-labelled phenol.
