Question

which method is used in the preparation of tlc plate​

Answer 1

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.

Answer 2

The method is used in the preparation of TLC plates are Pouring, Spreading, Dipping. (Option D) All of the above.

The TLC plate should be prepared as follows:

1. Pouring: The adsorbent is dissolved in a slurry and poured into a glass plate set on a level surface.

2. Dipping: the entire plate is dipped in the slurry.

3. Spreading: The adsorbent is formed into a slurry and deposited in an applicator, which is then moved across a plate to spread it out.
