about gas chromatography!
« on: December 18, 2004, 06:46:55 PM »
as you know i am doing with this thing...so here is another depressive question  ;D hope for replies! thanks in advance!

it says when i choose the liquid stationary phase, then i have to use the rule; "like dissolves like". i wonder if the compound i am interested in is polar, this means that the stationary phase i choose must also be polar, right?  how would you predict the retention time of my compound? would it be eluted faster or slower than other nonpolar compounds?
BTW how can polar compounds be interacted with each other?

thanks again!

Put the structure of the molecule of interest in the thread. And we'll tell you if its polar or not.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

sorry for being late with responding, guys! HAPPY NEW YEAR to all   :beerchug:

sorry for not being specific. i just did not get how polar components interact with each other.
