Forskningsöversikt (refereegranskat)abstract
- This review updates our knowledge on pressurised liquid extraction, PLE (also known as accelerated solvent extraction and pressurised fluid extraction) of persistent organic pollutants such as polynuclear aromatic hydrocarbons and polychlorinated biphenyls from environmental matrices. The basic experimental set-up is presented, and parameters influencing the extraction process are discussed. PLE can be used for a broad range of applications, and clearly has the potential for replacing tedious classic extraction methods such as Soxhlet extraction. Copyright (C) 2000 Elsevier Science B.V.

- The use of mono-crystalline silicon microstructures for high-speed and high sensitivity protein mapping and protein identification is presented as an important contribution within the field of proteomics. The various approaches for handling minute amounts of protein sample are described. Piezoelectric dispensing units developed in-house are being used for sample-handling and the generation of 60-pl droplets, interfacing with high-density microchip MALDI-TOF MS target plates having an array density of 4000 nanovials/square inch. Examples of applications to microtechnology, and future trends in our research are outlined. (C) 2001 Elsevier Science B.V. All rights reserved.

Mini/micro thermal biosensors and other related devices for biochemical/clinical analysis and monitoring
- 2000
-
Ingår i: TrAC - Trends in Analytical Chemistry. - 0165-9936. ; 19:5, s. 340-349
-
Tidskriftsartikel (refereegranskat)abstract
- The present review discusses the recent developments in the design, fabrication and implementation of mini/micro thermal biosensors for biochemical/clinical analysis and monitoring. The principle of thermometric sensing and recent developments in microfabrication technology are introduced, followed by their adaptation to thermometric devices. The instrumentation of the mini, micro and multisensing thermometric devices are described followed by their application to a variety of biochemical/clinical analyses. Other developments in material design and hybrid devices for thermometric sensing are also mentioned.

Towards a new Certified Reference Material for butyltins, methylmercury and arsenobetaine in oyster tissue
- 2004

Tidskriftsartikel (refereegranskat)abstract
- Increasing awareness of the determination of chemical species in the environment evolves jointly with the need to control the validity of analytical measurements in a wide variety of matrices. There are few Certified Reference Materials (CRMs) available for various chemical species, and they are certified for species of one single element (e.g., species of tin and mercury). Three years of collaboration within the framework of European Commission research programmes involving more than 20 laboratories have made it possible to produce an oyster reference material for species of tin, mercury and arsenic (BCR-710) and to perform the necessary experimental work for its certification. This article summarises the feasibility study and describes the various steps in the preparation, production and characterisation of this material for its content of arsenobetaine, methylmercury, tributyltin and dibutyltin. These steps included stability and homogeneity testing as well as value assignment based on a collaborative approach involving a group of European laboratories. Further work is going on to certify total contents for a range of trace metals.
