C'était—cette aquarelle—le portrait d'une jeune femme pas jolie, mais d'un type curieux, que coiffait un serre-tête assez semblable à chapeau melon bordé ruban de soie cerise ; une ses mains gantées mitaines tenait cigarette allumée, tandis l'autre élevait la hauteur du genou sorte grand jardin, simple écran paille contre le soleil. […] c'était actrice d'autrefois en demi-travesti. Mais son mel...
A high performance liquid chromatography method was studied for determination of 18 ?-glycyrrhetinic acid in Glycyrrhiza glabra L. (licorice) extract. The operating condition were C-18 reversed phase column (VP-ODS, (250×4.6 mm, 5 mm)) at room temperature, acetonitril/phosphoric acid (3/1) as mobile phase, at flow rate of 0.6ml/min (0-8min), 0.4ml/min (8-20min) and UV detection at 230 nm. The...
Today, 2D online or offline liquid chromatography/mass spectrometry is state of the art for the identification of proteins from complex proteome samples in many laboratories. Both 2D liquid chromatography methods use two orthogonal liquid chromatography separation techniques. The most commonly used techniques are strong cation exchange chromatography for the first dimension and reversed phase s...
This review aims at summarizing the most recent updates in the field of acrylamide (AA) formation (mechanism, conditions) and the determination of AA in a number of foods (fried or baked potatoes, chips, coffee, bread, etc). The methods applied for AA detection [Capillary Electrophoresis-Mass Spectrometry (CE-MS), Liquid Chromatography-Mass Spectrometry (LC-MS), Non-Aqueous Capillary Electropho...
