Web17 jan. 2024 · Extracellular buffers include bicarbonate and ammonia, whereas proteins and phosphates act as intracellular buffers. The bicarbonate buffering system is especially key, as carbon dioxide (CO 2) can be shifted through carbonic acid (H 2 CO 3) to hydrogen ions and bicarbonate (HCO 3−): … Ionenuitwisselingschromatografie (IC) is een chromatografische methode ontwikkeld midden jaren zeventig van de 20ste eeuw. Nadat was aangetoond dat anion- en kationmengsels geanalyseerd kunnen worden door middel van HPLC, werd een manier ontwikkeld om stoffen te scheiden en te analyseren op basis van hun ionaire eigenschappen. De mobiele fase (mp) bestaat uit een waterige oplossing met ionen en de stationaire fase (sp) bestaat uit een ionenwisselaarhars. Naast de dete…
