Purge and Trap Gas Chromatography

[@mrphysh]

Thanks. I did purge and trap for several years. In retirement, I look back and my understanding deepened.

[@mrphysh]

thanks.. I am just now seeing this

[@titansfolly2660]

This was VERY well explained. The overlay pictures, bubble jar, and the wood block were really nice touches and really helped me visualize the process.

[@mrphysh]

thanks for the comment. this is one of my favorite videos

[@mrphysh]

You are very welcome. I was employed as a GC/MS operator for many years..

[@PhaseSeparationScience]

This is an excellent video. Well done, and clearly a very knowledgeable speaker !

[@mrphysh]

Thanks. This one of my favorites.

[@KVlogz7]

is it the helium that goes onto the column after causing bubbles?

[@antarl22]

typically, what pressure would you bubble the He through the sample?

[@swapnalide]

thank u so much for the lucid explanation.. :) it really cleared my concept and for my exam tomorrow.. :)

[@louisrogissart5383]

thx, well explained. now i understand my drawing in my course

[@tony284huang]

Can we can use purge and trap to analyze Iodoacetic acid in water?

[@michaelduddikoff4396]

This was a very good video mrphysh. Thanks.

[@mrphysh]

thanks, I worked in the field for several years. I never really understood it until after I left.

Thank you so much for this explanation! Hello from Norway!

[@mrphysh]

hello back, astonishing new world we live in!

[@mrphysh]

I think that this video is excellent. It makes me mad that the audio volume is not higher. Oh well. Be more careful next time!

[@mrphysh]

The boiling point is 208 C ..... purge and trap would not work with what I consider the normal parameters.

[@dennifelicious]

very well done! perfect,

[@galshiri]

Thank you for the video it helped a lot !! great explanation

[@mrphysh]

this is one of my favorite .. It is technically not that great, but I have no intentions of remaking it. I worked in the field for many months before I started to understand it.

[@mrphysh]

The bubbling is no different than blowing through a straw. The rate is fairly high......maybe as high as 50 ml a minute....no pressure

[@mrphysh]

Right... Helium is a byproduct of the natural gas industry. I think that is interesting. But it is something of a limited resource. There is nothing wrong with using nitrogen. In Europe they use nitrogen.
