Hi my name is Paul Dinsdale, I am currently studing a degree in Chemistry at the University of Hull. I was wondering if you could help me in a project on Chromatography that I have been assigned.

The task,

Produce a serious case studies on the most suitable Chromatograpic procedures for the following chemical mixtures/analytical problems in order to identify the components:

Nucleic acids

Powder containing illegal drugs (unknown type)

Residual (trace solvents)in industrial methanol

A sample of diesel oil

Pesticide residues from the skin of apples

contaminated river water (dead fish)

Sugars in root vegetables

Any help or information which you can provide would be greatly appreciated although i do realise that you are an extremely busy People, and may not have time to deal with my Homework problems!!!

Yours faithfully

Paul Dinsdale

I won't give the answers to your particular questions, however I will suggest that you check out www.acs.org and do some hunting around in the abstracts of the journals there. Look at various compendia (AOAC, Standard Methods for the Examination of Waste Water, EPA and possibly DEA documents, etc...) as well. All of these are covered in great detail in the literature. Start digging and have fun.

Also do a web search. Google (http://www.google.com) will very likely turn up relevant manufacturers' literature. PubMed (http://www.ncbi.nlm.nih.gov/PubMed/) will turn up more literature citations.

try the library. the purpose of the assignment was likely to get you to know how to use it. Scifinder will be most useful if your university has access

I think it is likely that your instructor is reading this site too!

To borrow a phrase from a past eloquent correspondent,

"Do your own homework dude!"
