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.
Nice explenation...refreches some parts...some youtube stuff if realy helpfull and good like this...knowledge is there to share! great demonstration...
(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...
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.
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.
