Purity, Formulations & Chromatography: Chromatography 🧪 GCSE Chemistry Learning & Revision

In this episode, we discuss chromatography.Chromatography is a technique used to separate the components of a mixture. This process relies on two phases: a mobile phase that carries substances and a stationary phase that impedes their movement. The separation occurs because different substances have varying affinities for these two phases. If a substance is more attracted to the mobile phase, it travels further; conversely, greater attraction to the stationary phase results in less movement. The effectiveness of separation can be influenced by the solvent used as the mobile phase.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams.
