Abstract
A simple and cost-effective method for making capillary electrophoresis (CE) detection windows is reported. A low-cost laser engraving machine equipped with a 450 nm high-power blue laser was used to remove the polyimide coating from the fused silica capillary by laser scanning the desired section. The entire process is automated and controlled in real time by software. This method can be easily adopted by many CE users for routine practice and is scalable for high-throughput production of detection windows across multiple capillaries.
期刊介绍：
The Journal of Chromatography A provides a forum for the publication of original research and critical reviews on all aspects of fundamental and applied separation science. The scope of the journal includes chromatography and related techniques, electromigration techniques (e.g. electrophoresis, electrochromatography), hyphenated and other multi-dimensional techniques, sample preparation, and detection methods such as mass spectrometry. Contributions consist mainly of research papers dealing with the theory of separation methods, instrumental developments and analytical and preparative applications of general interest.
