You should have gone to a trade school not a university if you do not see what an academic education is about. Or just attend a specialized course. But I should not be surprised you can't see a difference... 10 years in a university ?!
@@HappyGoLuckyMadDog I congratulate you your laboriously earned degree. I was 100% convinced it was "10 years of lectures in University with regards to GCMS". Are you familiar with sarcasm, DOCTOR?
I have one question regarding the temperature of inlet that is around 200 degree then sample is vapourized. After that it is introduced to column via carrier gas. Temperature in oven is ramping starting from might 30 till 220. The question is from high temperature of the inlet to slightly low oven temperature might lead a kind of condensation, how the sample still in vapour state during it 's journey to column. Plz illustrate.
mohamed mamdouh once the analytes get introduced onto the column, they are moving along from vapor pressure. Think of a humid day. There’s lots of humidity yet the temperature isn’t 100 C. The sample stays in vapor. Starting at a low initial oven temp allows a nice sample focusing effect but not really a condensation as that would imply we went back into liquid.
Sir can you please answer my query. Why in gc we are using split injector(high split ratio) instead we can make less concentrated solution which will going to save our carrier gas, analyte, standard.

So much thanks for this presentation. Rich content, attention grabbing, relatable and excellently done.
I learn more from watching this presentation than attending 10 years of lectures in University with regards to GCMS

4 years undergraduate as chemistry major + 6 years PhD as biochemistry :) yes 10 years in university

Excellent talk! It helped me very much in my pursuit of getting our neglected/abused GC-FID back in working order. Thanks!
Thank you sir, very useful and well presented.
This is a great video for GC work. What is the k value? Wish you continue more Tips & Tricks about GC. Thanks!
Great presentation thank you for your professionality
very nice , crystal clear clarity on subject, thanks a lot sir

Thank you so much for sharing this wonderful subject
Nice and helpful presentation for GC users
what can be the problem if you can no longer detect your lowest concentration sample?
Amazing talk. Thank you
Thank you for the information! Great jokes btw
Perfect. So good
So much thanks
Enlightening ✊

Yeah....good
