Sorry for may be easy question or the wrong question. But for this, and there are forums, is not it?;)
Help me please, I find the optimum mix of compounds for the GC separation. It is necessary for the internal operations in the laboratory.
so, I decided to examine the next question:
I understand that the best compounds for the GC - a volatile, low molecular weight and don't high polarity (PAH, ethers PCBs).
But I did not once meets with the data, which also affect such an indicator as the LogP. Tell me please, what is the physical and chemical values you use to confirm the detection of compounds in the GC or HPLC?
May be logD, pKa, Polar Surface Area or Polarizability may be...
I select pesticides.
It's easy to see the article and just believe it, but it is interesting to find an answer and have a theoretical experience.
With best regards
Dmitry
