Afsar,
Have you taken any courses at all (i.e. lab courses or theoretical courses) on HPLC or GC? If not you need to learn at least the basics of how it works, what columns are available and how they work, what is the solvent/additive strength for each type of chromatography, what analytes you can analyze with the detector you have in your lab and what other detectors are available etc before you start with the lab work. Plenty of this information can be found in the link below, which is a kind of virtual HPLC book in liquid chromatography. It is a petty that the authors have not updated it for the last several years.

Another good resource to start is the link below (as Tom would have said).

I am sympathetic with the limited resources situation and I have heard (or seen) situations where the office time of your supervisor is not your time...
I have seen in this forum a lot of Indians with experience on the field... maybe they could direct you on some nearby resources or send you copies of a relevant "copy-right free" manuscript...
