Chromatography of amino acids on sulfonated polystyrene resins.
The quantitative separation of amino acids by chromatography on columns of starch has sheen described in previous publications (l-3). In extending these investigations, a systematic study has been made of the separations of amino acids by elution analysis on columns of synthetic ion exchange resins. With a sulfonated polystyrene resin, Dowex-50, it has been possible to develop a chromatographic...
متن کاملSulfonated Resins
Ion-exclusion chromatography (IEC) has been widely used in the separation of carboxylic acids, finding applications in the analysis of food and beverages, pharmaceuticals, biological samples, and acid rain samples.1 The retention mechanism of carboxylic acids in ion-exclusion chromatography has also been investigated in many studies, and the factors which affect retention can be divided into th...
متن کاملNMR Analysis of Sulfonated Polystyrene
Atactic polystyrene (PS) has an amorphous structure. Compounds such as H2SO4 and SO3 are commonly used as sulfonating agents for various polymers, including PS. The main purpose of this work is to study chemical structural changes in PS arising from sulfonation through DSC analysis and NMR spectroscopy. An increase in the glass transition temperature (Tg) of sulfonated polystyrene and a decreas...
متن کاملEvaluating the Serum Levels of Calcium, Chloride, Potassium and Sodium in the Stroke Patients
Backgrounds and Aims: Stroke incidence rate has increased during the past 2 decades. The question of whether calcium, chloride, potassium, sodium levels are associated with stroke has remained controversial. The present study aimed to evaluate the serum levels of potassium, sodium, calcium, and chloride within stroke patients. Materials and Methods: The study participants consisted of 5...
متن کاملDirect Determination of Calcium, Sodium and Potassium in Fermented Milk Products
The aim of this study was the investigation of the possibilities of direct determination of calcium, sodium and potassium in the commercial and kombucha-based fermented milk products by flame photometry. Two procedures were used for sample preparation: simple dilution with water (direct method) and extraction with mineral acid. Calcium, sodium and potassium levels determined after mentioned sam...
