Thin Layer Chromatography (TLC)

We know how to perform extraction, which can separate compounds on the basis of differing solubilities. But what if they have the same solubility? Well there is another technique that utilizes differences in polarity, and it's called chromatography. There are many varieties of chromatography, but the best way to introduce the concept will be to look at thin layer chromatography, or TLC for short. Check it out!

You just summarized our 3-hour lesson into 9.5 minutes

[drewkrahn]

So much easier to understand than our lab manuals. Thank you!

[ramil]

Getting ready for the MCAT exam. Your videos are THE BEST on youtube for all of ochem and gen chem material! Thank you so much!

[Southwest_racer]

I don't know why o-chem lab manuals have to be mystery novels. Thank you for your videos!

[lalaland]

Since we’re on quarantine my Organic Chem lab professor is using your videos and basing the work he gives around your videos

[iuliiamairansaeva]

I'm happy you've decided to do youtube... Some of us watching you right now will become great chemists in the future, and you'll be one of the main reasons we'll manage

Was watching a video on NileRed about extracting urea from his piss, got curious how recrystallization works, looks it up, finds other separation techniques, doesn't understand what it means by "phase", and now I'm here. Chemistry's nuts. I'm not a student, at least not of any classes, I just really like learning about how things work, and your videos are super helpful. Thanks Dave <3

Column chromatography is basically the same process flipped upside down, though. Simple n clever.

DAVE. Keep up the good work. Thank you so much for your contributions. You really explain things in a manner that is so straightforward and easy to follow. I appreciate you so much.

Mahal na po kita Professor Dave. Ikaw po ang pinakadakilang guro na nakakapagpaintindi saakin ng mga bagay na mahirap intindihin.

I'm an msc student and you helped me pass my enterance exam and now helping with my final exams in grad school, you're a life saver! :')

[sarahholland]

thank you! prepping for lab quizzes using your videos bc they are so much easier to understand than our manuals

Very helpful for JEE! Love from India 🇮🇳❤

Being a visual learner instead of trying to understand material that needs to be read, I feel that this video on TLC should be shared with students that would like a better insight/understanding on this topic. From watching this video I actually learned that the TLC plate itself has hydroxyl groups that is dipole-dipole, allowing it to interact with other polar substances.

Jesus, man, your oc videos are helping me sooo much right now, thank you a lot! ❤️

[R_samurai]

Thanks a lot man! Our schools told nothing about how this is typically used as an analytic technique

[ginamarie]

great for visual learners, finally a video that makes it easy to understand. thanks.

[BIAKANOORWorld]

always satisfied with your explanation prof., a huge fan of you from India

[pallobbarai]

Thank you, your lecture is amazing, easy to understand, animation is excellent.

If only this video came out a few years ago... I wouldn't have looked like such a fool in my research lab haha
