Uncertainty is a performance characteristic that should be estimated in both quantitative and
qualitative results in order to improve knowledge of their reliability. Contrary to quantitative …

The uncertainty of measurement is the key indicator of the quality of any experimental result.
Proper consideration of this uncertainty is imperative when testing a sample against …

Solid-phase microextraction (SPME), using a polydimethylsiloxane/divinylbenzene
(PDMS/DVB) fiber, interfaced with liquid chromatography–fluorescence detection (LC–FD) …

A fast, simple, and sensitive HPLC–FD method is described for determination of ochratoxin
A (OTA) in pig kidney and muscle; a small mass (< 2.5 g) of sample and a relatively small …

The purpose of the previous, this, and subsequent articles in the series is to deal with the
fitting of a straight line to experimental data in those cases in which replicate observations …

The purpose of this article is to stress the importance of weighting in fitting straight lines with
replicated observations. Nevertheless, single response data are also taken into account …
