1. Inductively Coupled Plasma Spectrometry for Speciation Analysis : Development and Applications
Abstract : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.

3. 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

4. Quantitative Bioanalysis : Liquid separations coupled to targeted mass spectrometric measurements of bioactive compounds
Abstract : Performing quantitative analysis of targeted bioactive compounds in biological samples, such as blood plasma, cerebrospinal fluid or extracts from pig liver, put high demands on the ruggedness of the method acquiring the results. In addition to the complexity of the sample matrix, the bioactive compounds targeted for analysis usually have low levels of natural abundance, further increasing the demand on the analytical method sensitivity.
