HPLC - Normal Phase vs Reverse Phase HPLC - Animated

Support and hit like and/or subscribe =).
Basic info about Normal Phase and Reverse Phase HPLC.
There are two variants in use in HPLC
01. Normal Phase - HPLC
02. Reverse Phase - HPLC
The 2 variants depends on the polarity of the Mobile Phase and the Stationary Phase.

[@marina15554]

very simple yet to the point and clear! thank you!

[@wessammohamed9235]

Clear explanation... but I prefer it to be with voice.. anyway thanks 😍

[@32barber89]

Thank you so much for this clearly explained video. Although it would have been much better if the video speed was a bit faster and had a voice recording too! But super easy to understand, thanks AGAIN!!!!!

[@claral2533]

Thank you so much! This explains the concept in a very clear and easy to understand way. Keep it up sir!

[@reececowell6642]

Very helpful now i can finish my analytical chemistry assignment :)

[@faridyusuf1841]

Awesome video! easy to understand. Thanks alot

[@Andreijkmuyt]

It is all clear with the polar particles.But does a non-polar stationary phase really retain non-polar molecules because they have affinity? What force causes such affinity then?

[@myworldofinstrumentation6523]

Simple and useful presentation

[@javeriasaeed2074]

Thanks alot for saving my time & providing mh the best explanation possible ...💝

[@pablocardella5930]

Excellent animation! Very clear! Thanks!!

[@ironlotuses2162]

Better than some professors I would say

[@dhruvmini01]

This was extremely useful! Thank you

[@uyenst]

Thank you for your very clear explanation.

[@chinna2680]

Thank you so much sir it's very easy to understand 😊

[@Fl0wright]

Great video. But wish there was audio.

[@prathz1065]

Awsome, you saved my time👍👍

[@KriiZInQ]

This is just awesome, pls keep on making videos on everything. and it will have success

[@CamilaRodriguez-hv7ls]

So easy. Thank you!

[@mustafaaslan5910]

Great video thanks a lot !

[@agentgunnso]

thank so much! it helps me!

[@pradyumnauchale1526]

Very nice animation sir....well explained

[@miriamhernandezgarcia7238]

Nice video!! I understood

[@nakkellasatyanarayana9709]

Very good explanation, thank u sir

[@The_real_Sumaya]

Well done it is so useful

[@sabavatmamatha9389]

Thank you for this video

[@berraozcan3976]

Saved my life

[@user-fb4ee6ph1c]

Thank you very much

[@aisharai4491]

superb animation

[@En_hausse55]

Thank you so Much, this video is really helpful

[@zaouiamina5799]

شكراااا

[@PrabuddhaSachan]

Put some more video on hplc... nice video.. easy to understand...!!!

[@shaikabdullah..]

Well explained sir thank you so much

[@Red00731]

Hey i was wondering wha Programm do u use for your animations ?

[@mehmoodhassan5355]

thanks so much keep it up ....

[@kanapathysima9550]

Thanks for the clear explanation...

[@leilasvr7144]

thats dont have voice

[@Safrout007]

thank you very much ^^

[@zahrazara4492]

thank you it's clear

[@Surajcxscsingh]

sir but i don't understand how there will be attraction between two non polar molecules.

[@Dealcapon97]

+Surajcxs c.singh Like dissolves in like, they are not interacting based on charge.

[@easylearning981]

+Surajcxs c.singh All molecular interactions are fundamentally electrostatic in nature and can be described by some variation of Coulomb's Law. Non-polar molecules can be polarized momentaneously, for example by the repulsion of their own negatively charged electron clouds when they are located nearby to each other, so the oscillating dipoles sense each other and couple. This is a favorable attractive electrostatic interaction known as dispersive interactions. Meanwhile polar molecules in the column are experiencing stronger interactions between them. That is why polar and non-polar compounds tend to repeal each other, as you can see trying to mix some water (polar) and vegetable oil (non-polar) in a glass. :-)

[@farahzahar7830]

oil(non polar) still will be separated from water(polar).

[@catarinalemos1841]

One question when u have HPLC -Normal Phase your solvent can be hexane cause this molecule is Non Polar like Mobile Phase isn´t it?

[@dhamot.k1561]

this is simple as simple

[@pankajpundir4497]

easy to understand d concept ...thnku so much ...will u pls upload more videos relates to hplc

[@basantmohamed4610]

why one of the main use of normal-phase chromatography is for separation of isomers???

[@gerrytan8164]

Hey everyone, im a little unsure about this. For reverse phase hplc, if the non polar moves slower through the stationary phase, what will be affected?

[@zahrazara4492]

the speed of polar particles which are getting out will be affected

[@aposvlah1855]

gerry tan why the polar bind then polar??

[@khloudmoh1030]

Thanks so much..

[@ChemistryTipsTricks]

Thank you sir

[@darshandarji8440]

I have one question sir Is that
Is Stationary phase and identifying spot both are having same state like polar or nonpolar....?

[@pharmasolutionpakistan7668]

Good

[@beatrizfreitas9034]

Is the sample to be analyzed in the normal phase polar or non-polar? And in the reverse phase?

[@theoryvan5784]

thankyou muchas gracias danke schön terimakasih

[@mobarokkorim7902]

good

[@elenagouitel6041]

this is good video yet there is no sound?? Thanks

[@Bripirate]

So much to be said for the difference between normal and reversed phase HPLC, but this video doesn't say shit!!

[@malomonifemi5560]

Am I the only one not getting any audio?

[@neetudhaker8735]

Mujhe bhi samjh aa gya

[@appleseeds5603]

Bless u
