WebAug 23, 2024 · As stated earlier, TLC plates (also known as chromatoplates) can be prepared in the lab, but are most commonly purchased. Silica gel and alumina are among the most common … TLC plates are usually commercially available, with standard particle size ranges to improve reproducibility. They are prepared by mixing the adsorbent, such as silica gel, with a small amount of inert binder like calcium sulfate (gypsum) and water. This mixture is spread as a thick slurry on an unreactive carrier sheet, usually glass, thick aluminum foil, or plastic. The resultant plate is dried and activated by heating in an oven for thirty minutes at 110 °C. The thickness of the absorbent …

WebMar 13, 2024 · Sorbtech Preparative TLC (Prep TLC plates) Prep TLC, or Preparative TLC, is used for purification and isolation of analytes from impurities on a larger scale than traditional TLC. Prep TLC is a fast, inexpensive, and useful technique for the purification of small quantities of sample. WebTLC plates typically have a fluorescent material ( e.g. zinc sulfide) in the silica gel, which causes the spots to appear dark against a green plate. An iodine chamber can be used for thiols, phosphines, and alkenes and works in about 50 % of cases for alkanes.
