I'm not sure if this is an error on my behalf, but when I go into your sandbox, your first image covers your page (image on the right). Please double check

Lead

It's great that you shortened the lead section and removed unnecessary information. Your introductory sentence summarizes the topic well, and the lead is concise and well-focused. Some minor suggestions: On your second paragraph first sentence, I recommend including "(known as the stationary phase)" into your sentence without brackets -- just with a comma.

The part where you mentioned "the plate is viewed under UV light or is stained", I agree with the stain part, but for UV light, I think you should be more specific on the word, "colourless" -- in UV-light range maybe?

Content

I liked how you removed some TLC images that had the same messages. I also agree with your new formats.

However, I suggest categorizing the Plate Preparation, Development Chamber Preparation, Development and Visualization as a sub-heading instead of putting them in point-forms. As the contents for each section is not small, putting in point-forms may not be the best choice. I also think Separation process and principle should be another section. I also suggest changing the title "Technique" to "Procedure".

Also for the very first sentence of your separation process and principle section, I don't think "competing for binding sites" is not necessarily the basis of separation of compounds. I checked your reference, and your reference states that "affinity" is the basis of separation. I think affinity is a better word for this (or the original sentence was fine as well).

I also don't think it was necessary to remove resulting word for "move higher up the plate ( resulting in higher Rf)". In fact, I think it is better with the resulting included. Same for the smaller Rf.

Check your first sentence of your last paragraph under the Separations principle section. I believe this is a run-on sentence. Also, is "system" necessary after "solvent"?

For analysis section, your intro sentence stated that you will be listing out "several methods". But the following points were more characteristics of some compounds (not method). You should either change the intro sentence or change up the list.

I'm not sure if you mistakenly kept the "Plate preparation" section from the original, but this should be removed if you included this information under Technique section.

For applications-reaction monitoring and characterization section, I do not entirely agree with "Once all starting material is gone, the reaction is complete". I think in some reactions, it is not possible to have all reagents to be consumed (especially the ones that aren't limiting reagent). Maybe double check on that statement.

Tone and Balance

Great balance and the article is neutral throughout.

Sources

The sources are reliable and are neutral sources.

Organization

Overall organization is much improved, but small suggestions for organization is listed under content section above.

Images and Media

Other than the very first image that is covering most part of the page, all images and media sources are good!
