Sensitivity and selectivity studies in capillary electrophoresis

Popular Abstract in Swedish Vad arbetar en analytisk kemist med? Exempel på kemiska analyser är att en idrottsman ska dopingtestas eller att eventuella föroreningar i vattnet från en bäck ska bestämmas. Den analytiska kemistens problemställning är vanligtvis att identifiera (kvalitativ analys) och mäta upp (kvantitativ analys) innehållet i ett prov. Ofta är de intressanta ämneshalterna mycket lågaCapillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.

New Possibilities using Modern Optics in Paper Production

During the last decades the need to control the paper production process has grown, due to the technological development and the continuing increases in quality demands. Recent development of sensors and fast, high-capacity computers open up new possibilities for the development of high capacity monitoring systems for the paper industry. Optical methods have advantages for performing fast and high

A survey on trellis termination alternatives for turbo codes

Numerous strategies and methods for trellis termination of turbo codes have been presented and proposed in the literature. In this paper the most common trellis termination methods are compared and their relative performances are investigated. An important observation is that the performance of a termination method is highly dependent on the particular interleaver choice. Conclusions should thus b

Medborgarna, politikerna och sjukvården : En studie av attityder och demokrati

The actors in focus here are the citizens and the politicians. We are studying their opinions on two central issues of health-care policy during the period 1981-1991. The aims of the dissertation can be summarised as follows: - to study the compositions of citizens´attitudes to health-care provision and policy - to examine the value of using different methodical approaches when studying health-car
