Chromatography

[logicerr]

A BEAUTIFUL demonstration! Thanks for posting!

[Arjun072]

magnificent video i was easily able to understand about chromatography thanks a lot

[saptarshisen007]

want more videos to explain hplc,hptlc,etc.......

[saptarshisen007]

awesome

I hate this video cause I'm a pupil =)

thanks dude



[TheAclark109]

great video...what is the song i love it too!

[karil15]

this is soooooo cool oo

[enchantedMALE]

fantastic! Thank you!!!!!!!!!!!!!!

[chcolatteizzle]

that's cooool! :D i like the music too!!

Ah Chromatography, one of the greatest boons in Analytical and Organic chemistry. The history behind this technique is very sad. It's too bad Mikhail Tsvet was never around long enough to see his invention take the world of chemistry by storm.

this is the only video that has help thanx nnnnnnnnnnnneeeeeeeeeeeeeeeeee­eerrrrrrrrrrrrrrrrrrrrrrdddddd­ddddddddddddddd

[wtfthu]

Thank you!

This was a great explanation! The guitar was bit distracting, though.

[ThoseLatinoKids]

amazing. best video in your channel =D

[adoool777]

thx

[mdogrnc420]

very good video and easy to understand

I like that you showed the funnel underneath. MIT don't use one in their digital lab manuals. now have the sexy lab girl paint some of those on her and disco tech dance :P

Question for the chromo guys! If I've run TLC's and have a rough Rf value for compounds that I can't normally see under UV or without destructively staining, and I want to purify a gram, can I transfer the Rf with any degree of accuracy to a column with a similar packing? My plates are 60A silica, so 60A silica in a column, can I use similar elution times? There must be a known value for the sol. volume on the plate, which I could transfer to a similar column without collecting endless fractions

excellent, superb

[ferdowzruqman]

my teacher showed this in class. great n colourful demo. great music too.

[dinocar77]

thanks alot

[Casablanca530]

aww yeah great chem video, i love the lights display

[Ryuusenka00]

what is the TLC plate?what is it exactly?

[lexichronicle2]

@Ryuusenka00 It's a piece of glass, plastic or aluminium that's coated in very, very fine, pure silica. The grains are tens or hundreds of atoms across, to create a super uniform, smooth surface ~1/4mm thick (like a filter paper, but better; I still use filter papers for rough tests before the TLCs). The glass ones can be tricky to cut by hand, even if you're used to snapping tiles for DIY (same trick). need gloves with all to avoid contamination.

c0kement0s again....very well done!!!!....to sum up, of course, I would say the separation was due to the polarity differences between the substances being separated. Indeed, there are different stationary phases (reverse phase, normal phase) thus 'interaction' with the stationary phase is more general and appropriate.

Brilliant! I have spent 3 years scouring YouTube for chem flicks to show my students. Your demos are superior - both visually and musically. Perhaps this 'Apex' company has taken over. If you haven't sold out your artistic genius, would you please consider now posting vids devoted to the 'BIG' principles: a)Temp & Rxn Rate; b)Conc & Rxn rate; c)Surf Area & Rxn Rate; d)Sythesis rxn; e)Decomp rxn; f)Single Displ rxn; g)Double Displ rxn; etc.

Your stuff has been the best I've seen in 3 years!

Now that, is awesome.

What kind of liquid transfering devices are those? The one in your hand on the 16th second shot.
