I've read it one million times in my theory book of analysis and with a 8 min video I understood it better than ever

Seriously this is the best video on yt as of now for spe

Really helped me understand this concept better for my lab class. My instructor sent me a video which was very difficult to understand, but this was much more comprehensible. Thanks

Really awesome job guys! Thank you!

Thank you this help out to undestand better SPE . Really nice moderators

Thank you, very clear demonstration. Also, it was nice to have Ashmeeta there to represent the human species! 😀

love the explanation thank you!

Nice work!

Nice!!!

First of all, thank you very much for the tutorial. It is really useful. I wanted to ask if the conditioning of the direct phase columns is the same. Thanks so much again!

Great video! I think the best so far I have watched. But I would like to ask a question: Is it advisable to use MeOH throughout if acetonitrile is not available?

Thanks!

A really good and detailed video. I am just wondering if i need a large amounts of samples how do i go about. Like if my sample introduction system requires atleast 10m of a sample.

Thank you, iam an undegraduated student, and i use this methode to separated my peptide sample

We are glad if it was helpful! Please let us know if there are any other demonstrations you would like to see in the lab.

Im a Forensic chemistry student and if never done a Solid Phase Extraction. tho it does look very similar to a Resin Exchange Chromatography experiment that i've done but fortunatly for the sake of time the experimenter could control flow

Hey, can we perform this for extraction of Isoquercitrin from petals of Dianthus.pavonius?

the column of C18 is only a cm or 2 in length. far shorter than the normal phase columns i've seen on vid's here on u-t. could you comment on this feature of C18 columns , please

Hi is it possible to use this method for the determination of concentration of caffeine

I want this manual Solid phase extraction kit I.e. Spe cartridge and push rod. Can you provide me the complete set up at least cost

the chatter ends at 3:38 ... then the experiment begins

Before eluting the samples, do we have to dry the cartridge?

While you don't have to, it is an option to dry the cartridge before eluting the samples. By taking this step it helps further disrupt the stationary phase/analyte interaction to promote elution.

What solvents are the dyes originally in?

Hi! Great question, for this demonstration we used an aqueous based dye solution.

@@Phenomenex Is that why you passed water through the column before you injected the samples?

im sure its totally fine, and im just weird, but the micropipette sitting horizontally with the tip on drove me a little crazy

Hey Josh, we are so sorry about that! Which part of the video are you referring to? Because I am sure that would make us a little crazy too.

it only matters if there is fluid in the tip

THIS is solid phase extraction? It's just a typical column chromatography for god's sake. Why is it not just called column chromatography?
