Initially, cryo-fluorescence spectroscopy of polycyclic aromatic compounds was my main research area (see my literature list). Very well resolved spectra of individual PAHs could be used for fingerprint identifications of very small amounts of compounds. The technique was further developed for application on fractions separated by HPLC. The spectra were stored in a spectral atlas GRAND.which was developed during several decades. GRAND was further expanded with lots of other properties of PAHs such as room temperature fluorescence and adsorption spectra as well as physical properties of PAHs.
I have been engaged in developing various clean-up techniques. In particular, dynamic micro wave extraction, was created by us as a pre step to several SPE/HPLC/GC systems. Small amounts of sample could be used, thus giving low LOD due to the use of the entire sample entered to the on-line separation system.

The theory of separation has for long time been an important part of my research. Mostly GC separation systems has been studied, but initially both reversed- and straight phase HPLC were studied and new phases were synthesized. During this time, several theories for the prediction of retention times were developed (se my literature list)
Statistics in analytical chemistry
Based on my background in Mathematics and Physics, I have been an eager supporter for the use of statistics in Analytical Chemistry. Basic statistics and experimental design is part of this. As a consequence, I have developed an easy to use computer program, WinStat, that can calculate and visualize most statistical situations that will appear in the development of data generation within the discipline. WinStat (currently vers 3.24) can freely be accessed from this page.
Simulations of the chromatographic process
In a current project, a method for simulation of separation is developed in order to predict retention times with high accuracy in temperature programmed GC. Thus optimization of an entire GC run of complex samples can be accurately made within seconds or parts of seconds. This can be performed by the computer program “GC Interactive Simulation” for the Microsoft/PC environment that I am presently developing. The program can readily be used in education, where the effect of altering column dimensions, flow rates and phase types immediately can be studied. Simultaneously, compounds can visually be followed in the column and the resulting chromatograms can be generated and studied. FID and EI/MS detector responses are simulated as output.
