Comparison of ionisation properties of aetma-labeled saccharides with common labels
Partyka, Jan ; Foret, František
We have tested (2-aminoethyl)trimethylammonium (AETMA) as a label for analysis of oligosaccharides by capillary electrophoresis with electrospray (ESI) mass spectrometry detection and compared its performance to taurine, 2-aminobenzoic acid, 2-aminobenzamide and 8-aminopyrene-1,3,6-trisulfonic acid. The AETMA-labeled saccharides were provided higher ionization signals in positive mode than native sodium or ammonium adducts and equal or higher signals than saccharides labeled by the more commonly used labels tested in this study.
Capillary electrophoresis with contactless conductivity detection of cationic-derivatized oligosaccharides
Partyka, Jan ; Foret, František
The oligosaccharides were derivatized by quaternary ammonium label and separated by CE with contactless conductivity detection.
