I used Thin Layer Chromatography to analyse different brands of aspirin 
tablets, using pentan-1-ol as the moving solvent. I also ran aspirin and 
salicylic acid on the chromatogram. I found aspirin in all the tablets, 
but I found something else in Anadin tablets and I want to find a table of 
Rf values to check what it is. Do you know where there might be some? I 
have already tried Chemistry Data books and Search Engines. Thankyou.
