1. Organosiloxanes containing cyano groups for capillary chromatography
Abstract : Methods have been developed for the preparation of capillary columns coated with organosiloxanes containing cyano groups. A procedure was developed for surface modification of the capillary tubing, by means of high temperature silylation. Such a modification gives deactivation and creates a surface suitable for coating with cyanosilicones. READ MORE

2. Organic Phosphorus Compounds in Aquatic Sediments : Analysis, Abundance and Effects
Abstract : Phosphorus (P) is often the limiting nutrient in lacustrine and brackish eco-systems, and enhanced input of P into an aquatic system might therefore negatively impact the environment. Because modern waste water manage-ment have reduced external P input to surface waters, internal P loading from the sediment has become one of the main P sources to aquatic ecosys-tems, in which relatively unknown organic P compounds seem to be more active in P recycling than previously thought.

3. Development of Techniques and Methods for the Quantitative Analysis of Endogenous Substances by Microcolumn Liquid Chromatography Coupled to Mass Spectrometry
Abstract : Liquid chromatography-mass spectrometry (LC-MS) is a powerful technique for the analysis of endogenous compounds. The introduction of electrospray ionization (ESI) as an interface between LC and MS has contributed strongly to a trend towards miniaturization of LC, due to the possibility to perform ESI at low flow rates.

4. Integrated Micro-Analytical Tools for Life Science
Abstract : Advances in life science require knowledge of active molecules in complex biological systems. These molecules are often only present for a certain time and at limited concentrations. READ MORE

5. Microscale Tools for Sample Preparation, Separation and Detection of Neuropeptides
Abstract : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. READ MORE
