Abstract:
A new, non-invasive chamber sampling technique for HPLC analysis of human epidermal urocanic acid isomers is described. Easily processed samples are obtained in a rapid and non-invasive manner, without discomfort to the patient. HPLC data from chamber samples are reproducible, and recorded urocanic acid isomer levels are comparable to those measured in samples taken with tape stripping technique.
