I learn more from watching this presentation than attending 10 years of lectures in University with regards to GCMS

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 ?!

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

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.

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.

what can be the problem if you can no longer detect your lowest concentration sample?
