Using nonequilibrium capillary electrophoresis of equilibrium mixtures for the determination of temperature in capillary electrophoresis.
Until now, all methods for temperature sensing in capillary electrophoresis (CE) relied on molecular probes with temperature-dependent spectral/optical properties. Here we introduce a nonspectroscopic approach to determining temperature in CE. It is based on measuring a temperature-dependent rate constant of complex dissociation by means of a kinetic CE method known as nonequilibrium capillary ...

Determination of histamine in tomatoes by capillary electrophoresis.
An improved capillary electrophoresis assay for histamine in crude extracts was developed and used to determine histamine levels in a selection of tomato fruits and pastes. Performance in terms of reproducibility and sensitivity was optimized by use of a high sensitivity detector flow cell, sodium hydroxide rinses, and a voltage gradient. The method was linear down to 0.2 microgram/mL (signal-t...
متن کاملDetermination of L-Ascorbic Acid in Tomato by Capillary Electrophoresis
In an undergraduate bioanalytical instrumental lab, students use capillary electrophoresis to quantify L-ascorbic acid (vitamin C) in food samples. The students are tasked to prepare standards, to obtain the calibration curves, and to determine the quantity of L-ascorbic acid in tomato samples (Lycopersicon fruit). A discussion about the function of each component of a capillary electrophoresis...
