Part 16: Column Chromatography - Frontal, Displacement and Elution Techniques

[@arunshelkeavs2918]

Tomorrow is my exam...i was totally blank about the development techniques of chromatography..but u rock sr....Thank u sr...with comparison u explained it very well....

Thank you for your explination and your explination is very welll

[@pharmd221]

In displacement analysis used to separate compounds having greatest affinity for stationary phase .

[@pharmd221]

In frontal analysis compound Wih least affinity for stationary phase and higher affinity for mobile phase eluted out . Only one compound in pure form is eluted in frontal analysis.

[@prasannakumar1614]

Great explanation sir.. i improve my knowledge from ur channel... Thank you very much puspendra sir 😍

[@pkclasses100]

Thank you for the appreciation. Keep Watching and Share the Video Link with your friends and help us to spread the knowledge. 👍

[@aksaisac]

Great explaination...easy to understand... thankyou so much sir😊

[@pharmd221]

Fractions of the samples come out of the solvent Elution analysis Simple elusion Gradient elusion

[@yathiroyal2002]

Excellent explanation sir thank you so much

[@dierdrekunene3165]

❤❤❤❤❤. Can't thank you enough sir. This was extremely helpful 😊

[@subhajitpurkayastha2260]

Thanks sir it helped a lot to understand

[@himanshukumar2110]

Thank You sir for such a good explanation. Thank You Very much.

[@shivkumarswamy861]

Sir it's good..bt u didn't gave reason in ellution analysis that y that solvent concentrating after each sample???

[@prernabansal8995]

Thanks!!! Very well explained!!!

[@user-mohamedibrahim2]

I'm from sudan thank u alot sir for this vedio♥️

[@shaliazahoor9905]

Sir plz present about low pressure column chromatography in which columns,matrix material,and stationary phases

[@pkclasses100]

Already explained please see the description 1st link. Contains all videos.

[@pharmd221]

Simple elusion Stepwise elusion Gradient elusion

[@user-vl8ns6ro7b]

It really helped me alot thanks dr ❤

[@user-vl8ns6ro7b]

Dr. Puspendra Classes i will now am gonna share it with my friends 😊

[@pkclasses100]

Thank you

[@madhutaylor8302]

Sir one doubt..if they ask elution methods..shud we include all the four methods..i.e isocratic, gradient, frontal, displacement

[@poomapooma9906]

Thank you for your clear explanation sir👏

[@pharmd221]

Quantitative analysis Solvents evaporated Pure form sample obtained Components having greater affinity for stationary phase come out

[@abhipsasatpathy179]

It was really very helpful.Thanks Sir

[@pharmd221]

Gradient elusion Composition of the solvent differ

[@pharmd221]

Column chromatography Elution analysis All compounds in 100 percent pure form is obtained Mixture of sample is administered a b c The band

[@ZafarIqbal-pf7vs]

Sir great effort ...:-):-):-)help a lot I also share with my friends

[@pkclasses100]

Thank you for the appreciation.. 👍🏻 Please share 👍🏻

[@upasanaraturi7384]

Sir this video is very helpful for us🙏

[@pharmd221]

Isocratic elusion means simple elusion

[@shreemclasseskota2267]

Is used sample always solid to put in a band form ......

[@seshagiriaitha1184]

Osmmm sir........ very helpfull lecture.....,😃

[@pkclasses100]

Seshagiri Aitha Thank you

[@aqsaaqsarana7500]

Good job

[@kashafroy3990]

Sir can u please differentiate btw frontal analysis and isocratic elution method? I mean in displacement method we use displacers and in gradient elution we change composition of mobile phase so these are clearly different methods but what about frontal and isocratic how can a person tell a difference in these methods without seeing the results?

[@ammukutty2202]

Great class❤️❤️❤️

[@kaleemsakhani5807]

why we don't get pure result in frontal but get pure result in eluation but the process of both is same plz explain sir

[@pkclasses100]

That depends upon the development of solvent system. If analyst is not able to develop solvent system for elution technique then only analyst will do frontal analysis because of no better technique available else elution technique will be done.

[@mohammedzeeshan8832]

In frontal analysis no separate mobile phase is used insted wo keep on adding sample solution(that act as a mobile phase)thats why we do not get cmplt separation where as in elution process we use a mobile phase which do not contain any sample solution.

[@pkclasses100]

Right 👍

[@Lalitha.sj2019]

Pls do more videos for us

[@pkclasses100]

I'm trying to upload maximum number of videos.

[@DeepanjaliSrivastav]

Thanku sir 🙏🙏🙏❤❤

[@prasanthkandelli4537]

Explain Chromatography types sir please explain

[@hidakhan07860]

Thanks 😊

[@ritikachouhan3529]

Thank uhh sir

[@haridev3815]

Thankyou

[@arshisheik9980]

[@MJTechs]

sir elution techniques and separation techniques both are same right in column chromatography

[@pkclasses100]

All techniques are used for separation.

[@kavyaviswanath9386]

thank u so much sir

[@hidakhan07860]

Thanks sir😊

[@sejalmalik3284]

Why is A in every fraction in frontal analysis? Some one please explain

[@pkclasses100]

It's an example only. It may be B or C also

[@sejalmalik3284]

@@pkclasses100 I meant one compound will remain throughout the stationary phase or its just shown that A is running through every fraction and finally reaches end

[@pharmd221]

In displacement analysis 100percent pure compound not obtained

[@umairhabib4618]

sir how graph is different in elution technique if all compounds give 100% result.

[@aiswaryanath9844]

Mixture may have varied concentrations of components .
