Thanks to all the team members for providing the wonderful content I hope you will make many more videos which helps many students, research scholars & others to get to know the basic understanding of such techniques & methods

I would like that she takes care of my column.

4:43 wait what, everytime i do that, the silica is stick into the flask

Somebody needs to teach the AI some chemistry terms so it can use proper words in the subtitles.

5:23 Jesus.. Christie is sassy...

So cool👏🏽👏🏽👏🏽

Why the hell do chemists wear big, permeable, fluid absorbent paint smocks while working with dangerous reagents instead of something imperviable and chemically resistant? Would certain chemicals have violent reactions with waterproof materials?

This video is AMAZING thank you for the help!

I wish everyone was this nice when addressing mistakes and hearing about your mistakes.

And later, Nathan gave Kristy a column of his own.

She's wearing her safety glasses but her hair is under them and the ponytail is swinging free.

Girls you have to protect yourself! Those guys have probably all kinds of std's!

I would flood the whole lab with argon! And everything is honky-dory!

Gosh, the grad cylinder was full of air!

Yeah… people who didn’t read the paper are dumbasses… lol 😂 my favorite part

thank you. If I used wet packing of silica gel to column (slurry), here, can I use any solvent for silica gel until reached slurried, or same mobile phase or must use only hexane.

happy new year and Thank you so much for this video. Is there standard to use silica gel in column, I mean if my sample a little bit like (0.01 gram), how much of silica gel use here? in contrast, if I have a lot of samples such as (1 gram or more), here, how much of silica gel have to use? I mean is there ratio from silica gel to sample to use in column, please tell me

If I have solid sample containing components, can I use any solvent to dissolve it? Or I have to use only the same mobile phase as solvent to dissolved sample? Another case, if must use same mobile phase, but my sample can not dissolve, here, please I need solution to this problem. can I use any solvent? thank you alot in advance

Nice

Very good, /tq.

4:54 no that's not a solution, it's a heterogeneous mixture.

No blood? This movie s not written and directed by Quentin Tarantino tho. Even though its an excelent one! lol

The first serious mistake was to not flush the black syringe. Second serious mistake when removing the black syringe! He should have tilted the latter and create an argon/nitrogen blanket over the liquid in the syringe. Third mistake was... is to use this video as a guideline.

Amé

There should be curtains for the lab showers so that if you spill a chemical on your body, you won’t have to worry about modesty.

great video

Awesome video! My mentor suggested I watch it and it was super helpful!!!!

In my lab, girls are not allowed to wear ear-rings when operating reactions. haha~

Very Beautiful Demo and Explanation!

Do you have a reference for the needle adapter on your rubber tube ?

What’s wrong with her face

Thanks to UCSD for this lecture.. Beautifully explained..👍

"first column" sounds like your losing your virginity or being inducted into a cult.

from HUST with assignments :(

Love the aphex addition

hi guys, BSED-SCIENCE 1-2A EVENING

Mandar

i didn’t know ucsd had japanese researchers

So would this be considered 'Art Haus' or more 'Classic Cult"? Also, I didn't go to school for serious Chem, do people really think running Flash Chromatography more slowly gives better separation? *SMH* I guess they're confusing it with crystallization?

All is well, except for TLC in a cup. There must be a Camera for TLC, saturated with eluent pairs.

Great🌺👍

thanks

I can answer this conundrum. You wear a lab coat so morons will believe every word coming out of your mouth without a second thought.

Is the lady at (4:30) really writing backwards? 🤔

I came from Mrs. Guevara class °<°
