The development of a method for the simultaneous determination of glycine, triglycine and fructose using UV/vis and evaporative light-scattering is presented. The study formed part of a research project dealing with the recovery of functional peptides from aqueous streams on an industrial scale using absorption or related technologies.
The second part in this series focuses on the variables in large data tables, looking at the vocabulary used by PCA experts, and explaining some of the background to the method. It further provides practical examples of how these variables operate in practice.
In this article, the authors look at ways to increase sample throughput for routine environmental analysis. Several strategies aimed at enhancing laboratory productivity are highlighted and illustrated with from-the-floor applications.
The authors discuss the issue of meeting the demands of regulatory compliance whilst ensuring good scientific practice. A number of requirements from 21 CFR Part 11 are cited to demonstrate the importance of applying the principles of risk analysis.
