Anti-HIV quality assurance programs in Australia and the southeast Asian and Western Pacific regions
Springer Science and Business Media LLC - Tập 6 - Trang 168-172 - 2001
A. Gust, Sandy Walker, Roderick J. Chappel, Elizabeth M. Dax
Anti-HIV testing is the most regulated area of laboratory medicine in Australia. These regulations have placed the National Sero-logy Reference Laboratory, Australia (NRL) in a unique position to implement a comprehensive quality assurance (QA) program for HIV testing. The elements of our QA program include pre-market evaluation of assays, external quality assessment schemes (EQAS), quality contro...... hiện toàn bộ
Absolute measurement system for low electrolytic conductivity of aqueous solutions based on van der Pauw’s theory using a flow-through cell
Springer Science and Business Media LLC - Tập 19 - Trang 433-438 - 2014
Bing Zhang, Zhen Lin, Xiao Zhang, Xiang Yu, Xiaoping Wang
A system was designed for measuring the low electrolytic conductivity of aqueous solutions based on an innovative application of van der Pauw’s theory. A four-electrode system with an axial–radial two-dimensional adjustment structure was used. A flow-through cell and a sealed system were built to avoid the CO2 contamination at low-conductivity values. In this paper, the new cell and the measuremen...... hiện toàn bộ
Linearity of calibration curves: use and misuse of the correlation coefficient
Springer Science and Business Media LLC - Tập 7 - Trang 281-285 - 2002
Joris Van Loco, Marc Elskens, Christophe Croux, Hedwig Beernaert
The correlation coefficient is commonly used to evaluate the degree of linear association between two variables. However, it can be shown that a correlation coefficient very close to one might also be obtained for a clear curved relationship. Other statistical tests, like the Lack-of-fit and Mandel’s fitting test thus appear more suitable for the validation of the linear calibration model. A numbe...... hiện toàn bộ
Homogeneity testing of reference materials
Springer Science and Business Media LLC - Tập 3 - Trang 51-55 - 1998
J. Pauwels, Andrée Lamberty, Heinz Schimmel
Homogeneity testing is of the highest importance for the certification of reference materials, as it should demonstrate the validity of the certified values and their uncertainties in the analysis of individual units or portions thereof. However, the conclusions drawn from the results of these studies may often be questioned. It is proposed to improve this situation by quantifying the effect of h...... hiện toàn bộ
