WebbINTRODUCTION Thin-layer chromatography (TLC) is a technique used to separate substances in a mixture. A TLC plate is typically a sheet of plastic, conted with a thin layer of a solid adsorbent such as silica gel. Small amounts of known and unknown substances are placed as small spots at one end of the TLC plate. Webb3 okt. 2024 · Before doing TLC, the sample was diluted with ethyl acetate and then applied to TLC plate. The mobile phase was ethyl acetate: methanol:hexane=3:1:1. I found it very hard to pull the compound...

Webb28 aug. 2024 · In the present study, an HPTLC (high-performance thin-layer chromatography) method was developed for the quantitative determination and validation of the curcumin in the methanolic fraction of Curcuma longa L. For achieving good separation of curcumin, the mobile phase of chloroform:methanol (97:3) was used.
WebbThin layer chromatography (TLC) TLC uses a thin layer of material as the stationary phase. This is normally in the form of a layer of silica gel on an aluminum or plastic backing sheet or silica impregnated glass fiber (so called instant TLC or iTLC, since it is much quicker than standard TLC). WebbThin Layer Chromatography (TLC) Thin layer chromatography (TLC) is a widely used separation technique for quantitative and qualitative analysis. It uses a thin layer of a stationary phase coated on a glass, plastic, or aluminum plate. A liquid solvent called the mobile phase carries the sample and separates it as it moves across the plate.
