Porous layer open tubular columns with immobilized trypsin for protein digestion
Knob, R. ; Křenková, Jana ; Petr, J. ; Foret, František
We have developed a monolithic porous layer open tubular (PLOT) column with immobilized trypsin for protein digestion. The PLOT column was prepared in a 10 (mikro)m ID fused silica capillary. Trypsin was immobilized on the monolithic surface and the developed enzyme reactor was used for protein digestion followed by on-line ESI/MS analysis.
Application of capillary electrophoresis in forensic science: Analysis of fireworks
Eliáš, Milan ; Maier, V. ; Knob, R.
In all samples of fireworks, K+, Na+, Ca2+ and Mg2+ ions were proved and quantified by the method of capillary zone electrophoresis using water solution of 10 mM 4-aminopyridine, titrated with hydroxyisobutyric acid to the pH 4.3, as background electrolyte and indirect UV-absorption detection at 200 nm. Pb2+ or Ba2+ ions were proved in few samples. The other selected inorganic cations were not proved in any sample of selected fireworks. NH4+ ions were not detected in any pre-blast samples, but they were established in some post-blast (glazed tiles) samples.
