Hi
I need to develop a reversed phase (C18) HPLC method for the analysis of theophylline and 1-methyl uric acid.
Any suggestions.

Maybe you can try this:
Ultrasphere C18 250 x 4.6
Mobile Phase: 0.05% Acetic Acid:Methanol 92:8
Flow: 1.0 ml/min

Try looking in the USP-NF or doing a search, there are many out there.
