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...
متن کاملChiral Capillary Electrophoresis - Mass Spectrometry
This review article addresses the developments and applications of capillary electromigration methods coupled on-line with mass spectrometry for chiral analysis. The multiple enantiomeric applications of this hyphenated technology are covered including chiral analysis of drugs, food compounds, pesticides, natural metabolites, etc., in different matrices such as plasma, urine, medicines, foods, ...
متن کاملDetermination of tetracycline residues in soil by pressurized liquid extraction and liquid chromatography tandem mass spectrometry.
An optimized extraction and cleanup method for the analysis of chlortetracycline (CTC), doxycycline (DC), oxytetracycline (OTC) and tetracycline (TC) in soil is presented. Soil extraction in a pressurized liquid extraction system, followed by extract clean up using solid-phase extraction (SPE) and tetracycline determination by liquid chromatography tandem mass spectrometry (LC-MS/MS) provided a...

متن کاملLiquid Chromatography− and Capillary Electrophoresis−Mass Spectrometry in Glucuronide Analysis by
Phase II metabolites, or conjugates, are highly polar, non-volatile and thermolabile compounds that need to be analysed in biological matrices such as urine, bile and plasma. Liquid chromatography (LC) and capillary electrophoresis (CE) are proven techniques for the analysis of compounds of this kind, but the standard detectors in LC and CE lack sensitivity and especially specificity. Coupling ...
