Thank you so much. 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 used wet packing of silica gel to column (slurry), here, can I use any solvent for silica gel until reached slurried, or must use only hexane. thank you
Very nice video. Thank you very much . Please tell me how do you determine the mesh particle size of the silica gell you use? Also how do you determine how much silica gell to use ?
happy new year. 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
great teaching sir.. I have a question... How to choose solvent for your mixture of compound?? In case if we have the ere extract how to choose solvent to separate the different compound???
this video has completely gone over my head....I literally didnt understood anything........What i have watched in other videos is that sample is mostly liquid and (here his sample is solid) and after its addition we further add solvent but in this video why professor has added so many things ........I dont know why he is has prepared ethyl acetate chloroform and so on.. !!!!! Plz if anyone know plz clarify this to me
I love your laboratory, the way you teach, and best of all the way you carefully carry out your experiments
Yo nigga!
Porvik Sharma you should not say that.
Way of explanation and recap students asking doubts excellent and live do the experiments can easily understand sir❤
These two students will get the award for best acting
the way you r describing is simply beautiful. thank you so much sir.
Chaalaa baaga cheppaaru sir.maku Chala ivi use avthundhi sir .thank you sir...🙏
I really learned more from your video . Thank you so much Sr. I would like to lean more about phytochemical analysis.
Thank you
Waoo Thats amazing way of experimental demonstration. Keep uploading further videos sir. Lots of Love and Huge respect from 🇵🇰🇵🇰
Really your teaching manner is excellent sir students also interacting in a nice manner
This gentlemen is very good teacher....
Best video on Coloumn Chromatography. Absolutely the best.
It's fantastic technic of chromatography
So so much nice vedio
Heartly thanks sir
I love your teaching style.....sir..
we are fortunate that the guy is our HOD in chemistry department
Wow sir that's amazing and
Now my doubts are clear before it I saw 5 or 6 videos of column chromatography but I didn't understand
Superb
More useful my degree first sem preparation, tanks for all
Tq Sir you teaching is really wonderful 👍👍👍🙏🙏🙏🙏
Wonderful explanation sir
Thank you very much
After watching such a nice explanation anyone can fall in love with chemistry ...Thank you sir for such beautiful explanation 🙏
What a superb way of explination!
Enriched with good knowledge.
well done actually so much effective to gather knowlwdge about chromatography.
Sir ,
I am Bangladeshi college teacher.
Now I salute you for this Technic.,🙏🙏🙏🙏🙏🙏🙏🙏🙏
How to choose solvent for mixtures of compounds
Good effort
Thank you very much for teach me column chromatography in a better way.Love from Bangldesh.
nice work
Wonderful sir. Tq.
Regular classes in the colleges should be lyk this nd every student ll get interested
Really awesome work sir
I loved u r teaching sir tnq sooooo much it is useful to me

Clear and good explanation
Super sir am working in pharma company. I undrstnd column cromotogrphy
Well done Sir
one doubt that why didnt we add silica gel fine powder itself to the column instead of adding slurry and then settling the silica?
Great teacher style sir
Best way to learn chemistry
Thank u soo much sir
Clear explanation.. thank you..
Amazing Thankyou Sir
Very intresting
WOW that's awesome 😍
Excellent sir
Students : sir.......???
Sir : keeps ready *ooooh!
Mains toh Hogaya yahan kya kar rahe ho?

Awesome sir
Well explained
Superb..
Video of phytochemicals analysis
Sand is required on top of cotton plug!
Why we use hexane as solvent to make the slurry ?
If I used wet packing of silica gel to column (slurry),
here, can I use any solvent for silica gel until reached slurried, or must use only hexane. thank you
Good video..
Very very very good👍 video so I kindly request to u plz upload the video of schiff base for project M. Sc
More useful
Very nice video. Thank you very much . Please tell me how do you determine the mesh particle size of the silica gell you use? Also how do you determine how much silica gell to use ?
big up i like it
thanks a lot.may allah bless you
Wow
Why only 2,3 vedios what's ur chanel name sir we want paper chromatography and other experiments also
Good morning sir ,
Can you please tell me the chemical formula of red and yellow compounds ?
Nice sir
Nice
Perfect!
Good students 🤣😂🤣
can any one tell me what are the names of compound A and B????
very nice from UU
I felt it was necessary for the girl to wear the goggles. because she was close to labs and her eyes were lower than your column.
Sir please make a video on gas chromatography
happy new year.
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
Sirf 2 student class me... 😂😂
Thanks 😊😊😊😊
why we used 80:20 mixture of hexane and ethylAcetate ????
great teaching sir.. I have a question... How to choose solvent for your mixture of compound?? In case if we have the ere extract how to choose solvent to separate the different compound???
trial and error with different solvent systems until separation on TLC is satisfactory
👏👏👍👍
👌🏻👏🏻👍🏻
beautiful
Thanks sir
i dont remeber a single thing
how to decide the height of column. please need help .
this video has completely gone over my head....I literally didnt understood anything........What i have watched in other videos is that sample is mostly liquid and (here his sample is solid) and after its addition we further add solvent but in this video why professor has added so many things ........I dont know why he is has prepared ethyl acetate chloroform and so on.. !!!!! Plz if anyone know plz clarify this to me
thanks sir
Thank u 🖤🤘
Very good teaching
👍🏻
