Analysis of benzalkonium chloride by capillary electrophoresis-tandem mass spectrometry

Trace analysis of benzalkonium chloride on skin by flow injection ionspray mass spectrometry-mass spectrometry.

A method for the analysis of trace-level benzalkonium chloride has been established using flow injection ionspray mass spectrometry-mass spectrometry with multiple reaction monitoring. Quantification was carried out using an external standard based on peak area summation of each benzalkonium ion (C8, C10, C12, C14, C16 and C18) in the mass spectra. The multiple reaction monitoring technique pro...

Capillary Electrophoresis/Tandem Mass Spectrometry with Array Detection

Structural analysis of chromophore-labeled disaccharides by capillary electrophoresis tandem mass spectrometry using ion trap mass spectrometry.

Disaccharides tagged with p-aminobenzoic acid (ABA) were separated by capillary electrophoresis (CE) and analyzed on-line with negative ion electrospray ionization tandem mass spectrometry (ESI/MS/MS). The formation of glycosylamine instead of reductive amination was selected as the derivatization reaction. In negative ion ESI, the glycosylamine approach provides more information on linkage and...

Analysis of Polymer Additives and Impurities by Liquid Chromatography/Mass Spectrometry and Capillary Electrophoresis/Mass Spectrometry

The analysis of polymeric materials can be quite challenging because such samples are often of complex nature due to the presence of various groups of additives, compounding ingredients, and fillers. Of special importance are stabilizers that protect the material from degradation by thermal stress during manufacture or from environmental impact during use. Apart from intact stabilizers, the deg...
