WebbThe mobile phase pH can change on standing, with ingress of CO 2 from the atmosphere for example, and a buffer can help to combat this effect to a certain extent. Similarly, volatile reagents, such as TFA, may also selectively evaporate, thus changing the eluent pH. WebbSince the pKa value for neutral sugars is about 12, neutral sugars can be retained in an anion exchange polymer if strongly-basic mobile phases is used. In such cases, an approximately 0.1-M sodium hydroxide solution is used as the mobile phase. In general, sugars elute in order from monosaccharides to oligosaccharides. buy party wear indian suits online
