Performing Thin Layer Chromatography (TLC)

oh my god you're actually my savior thank you

im watching your videos during my JEE prep to get better clarity for certain topics…thank you professor!!
much love from india :)

Nice video!! I was so confused when I was doing this lab😢

Thank you so much Mr. Dave for explaining so well and simple.

شجابني هههه 😂

Nice

you are awesome professor Dave thank you for this video

What solvent would you need for flavonoids from cabbages, professor Dave?

Thank youu professor

marvelous!!! simple, but has all the elements needed

Is that a fly in the solvent?

Very useful👍

amazing video, thank you professor

THANK YOU SO MUCH! This is way more helpful than reading a lot of techniques from the lab manual!

Keep the good work

Love from father of Pakistan 🇮🇳🇮🇳🇮🇳🇮🇳

I have a qustion. What if the extract sample we have is semi-solid, how do we dissolve it? and how to choose the appropriate solvent for a sample that has never been studied?

ok da

Ahh fisher my number 1 MSDS source

Very good and easy to understand

Hi!! I was wondering why you should cap the chamber for a few minutes before using it? Is there a specific reason for that?

Great video! Hope you can teach us how to use different stains to find out compounds that cannot be seen under the UV light.

great video, hope you do one one column chromatography (adsorption or flash chromatography) and explain how tlc can be used to effectively create an efficient solvent system for any purification work-up using the more common column chromatography.

Can a standard UV-C light (~253nm, for disinfecting) be used for visualizing plates at home? they are only like $10, compared to the mineral lights or light boxes used in labs which are hundreds of dollars.

when creating reference samples for the tlc spotting of known or unknown samples, do they have to be in aqueous solution or in a solvent, and does it matter how dilute the sample is?

How do you create an Iodine chamber for developing tlc plates?

In addition, if you wish to reuse a capillary you can dip it in acetone to clean it between spottings

My guy you still make videos???
You are a determined man
Respect

thank you chemistry jesus

You are great❤

Reminds me of my Botany practical in college

As a research chemist tlc is an important step in determining a reactions success. I actually learned tlc from your channel back a few years ago

Can’t wait to get to HPLC and GC, my specialty 😊

Another fantastic video loving this series

TLC can be used quantatively by using different concentrations of the same standard, and comparing the sample spot size to the standards.

is there a bug in your solvent?

What's the purpose of capping the solvent and letting it sit, before introducing the plate?

These are great. I am a sys admin for a lab and these videos allow me to ask informed questions of the chemists that work there.

i get you gotta pay the bills but PLZ look elsewhere before you buy from Thermo Fisher. They’re one of the most expensive vendors

i use TLC to estimate the THC content of my cannabis

I love these videos. Thank you. This helps to understand things a lot. I found out that j tolan lied about how far away he was on the 1000 mile video.

Great timing. I’m doing this lab next week

Cool

good ol' thin layer chromatography
thanks!

👍👏

Jesus, the spots are hella thicc. Use the tip of a sirenge.

Thermofischer is my favorite chemicals supplier. In my lab setting i always order from them, they provide the highest quality amongst the different chemicals that i work with.

Sir among Be and Ga which is more metallic element

Man ur such a god send. I literally have a TLC write up due tomorrow

Good

How does this experiment work when gravity doesn't exist?

LOL! Just kidding! I'm enjoying these practical lab videos. They're taking me back to my organic and inorganic chemistry days in college.
