Chromatography — TLC, HPLC, GC

T-Level: Science: Chromatography — TLC, HPLC, GC

What you'll learn

  1. 1

    Imagine dipping the corner of a paper towel into a glass of water — the water creeps up the paper, right? 🧪

  2. 2

    Here's a simple paper chromatography setup — the solvent (liquid) travels up the paper, and the mixture splits into separate spots. 🧻

  3. 3

    Drag the solvent level up the paper to separate the ink mixture into its colours. 👆

  4. 4

    Let's read a TLC plate — three spots appear at different heights. Which chemical is most soluble? 📝

  5. 5

    In paper chromatography, which travels furthest up the paper? 🧻

  6. 6

    HPLC (High Performance Liquid Chromatography) is like paper chromatography but with a narrow metal tube instead of paper, and liquid is pushed through under high pressure. 🚀

  7. 7

    Which two things are the SAME in paper chromatography and HPLC? 🧪
