Fingerprints found at a crime scene can be key in criminal investigations. A method to accurately determine the age of the fingerprint, potentially crucial to linking the fingerprint to the crime, is not available at the moment. In this paper, we show that the use of the enantiomeric ratio of d/l-serine …

Natural Deep Eutectic Solvents (NADES) represent a green chemistry alternative to utilization of common hazardous organic solvents. They were introduced by Abbott et al. [1], and were found to have a wide range of compositions and favorable properties. NADES are typically obtained by mixing hydrogen-bond …

This paper describes the development of one solid phase extraction method for a wide group of pharmaceutical and industrial compounds in wastewater that is analyzed with two LC-MS/MS methods.

The selectivity of the separation of some anthocyanins on Diasphere-11-C10CN stationary phase (phase I) is compared with the traditional reversed Symmetry C18 phase (phase II). It is found that, in contrast to phase II, phase I is effective in the separation of isomeric pairs of anthocyanins of 6-hydroxycyanidin- …

Aminozuren vormen de bouwstenen voor eiwitten en het is algemeen bekend dat deze een belangrijke functie hebben in vele biologische functies. Er is daarom veel belang bij de mogelijkheid om aminozuren snel en efficiënt te kunnen analyseren. De meeste amino zuren hebben een chiraal centrum en daardoor …

Result of the study on the exposure of imidacloprid on Lymnaea stagnails, have led to this study. The results indicate that imidacloprid might be metabolized to other components. Therefore the aim of the study was two folded: 1. To develop a method for the quantification of imidacloprid and its metabolites. …
