Hi, anyone can answer me, its possible to use GC for analysis solid materials by dissolving it in distinct solvent then inject it or GC only used for volatile materials.
The volatility of the substance plays a role when using a temperature program like when seperating a mixed sample like alcohol and diesel (The alcohol will come off first with a relatively low retention time and the diesel will seperate into all the substructures of diesel like heptane,octane decane and the likes all with distinct retention times.
(because my teacher keeps on saying the polarity plays an important roll, like the more polar particles remain behind while the rest goes through the tube) ?
It's because the inside of the column.. it can contain a substance that can be helpfull to sort out the materials after affinity or polarity…
нахуя этот эйр бабл нужен
Very interesting!

you should do infrared spectroscopy also. nice job though
cool video, nice really informative 😛
lol way to make yourself feel smart while barely answering his question.
thanks for the video!
awesome video, thanks!
very well done stuff
Good job on your video I liked it very much!
I liked your video very much.
i have a question? what's the temperature of the GC(detector,column,oven) for biodiesel using NaOH as catalyst and/or sugar-catalyst?

Exelente ! ;gracias ,desde buenos aires.
Where is the autoinjector? When was this GC made? the 1800's?
Get with the times and get an automated system. Nobody in the real world injects samples themselves.

Nice explenation…refreches some parts…some youtube stuff if realy helpfull and good like this…knowledge is there to share! great demonstration…
Very good, extremely helpful. especially the error portion.Thanks a lot !
