Microbeam-coupled capillary electrophoresis.
Within the first few microseconds following a charged particle traversal of a cell, numerous oxygen and nitrogen radicals are formed along the track. Presented here is a method, using capillary electrophoresis, for simultaneous measurement, within an individual cell, of specific reactive oxygen species, such as the superoxide radical ([Formula: see text]) as well as the native and oxidised form...
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 کاملA Benchtop Inductively Coupled Plasma Mass Spectrometer
Inductively coupled plasma mass spectrometry (ICP-MS) is an analytical technique that performs elemental analysis with excellent sensitivity and high sample throughput. The ICP-MS instrument employs a plasma (ICP) as the ionization source and a mass spectrometer (MS) analyzer to detect the ions produced. It can simultaneously measure most elements in the periodic table and determine analyte con...
متن کاملAnalysis of metallothioneins by means of capillary electrophoresis coupled to electrospray mass spectrometry with sheathless interfacing.
Capillary electrophoresis (CE) coupled to electrospray mass spectrometry via sheathless interfacing has been applied to the analysis of mammalian metallothionein (MT) extracts. In a rabbit-liver extract, four (MT-2C, MT-2A, MT-2D and MT-2E) out of six known MT sub-isoforms were unambiguously identified under three CE-resolved peaks. A fourth peak was found to contain MT-1A and/or MT-2B, whose m...
متن کاملCharacterizing biomolecules by electrospray ionization-mass spectrometry coupled to liquid chromatography and capillary electrophoresis.
Introduction Electrospray ionization-mass spectrometry (ESI-MS) is now a routine and highly sensitive method for the characterization of biomolecules, providing information on the molecular weight and the linear sequence at the femtomole level. The sensitivity and the mass accuracy of the technique is in many instances better than 0.01%. and masses differing by as little as 0.1% can be resolved...
