## Abstract A synthetic mixture of uroporphyrin isomers I, II, III and IV as free acids in the synthetic ratio of 1:1:4:2 was resolved by reverseβphase HPLC using a C0:PEL (ODS) 37β50 micron precolumn and a Micro Bondapak C18 analytical column eluted with acetonitrile (4%) in phosphate buffer (pH 6
## Abstract The potential of reverseβphase highβperformance liquid chromatography (RPβHPLC) for the separation of the tryptic glycopeptides of the hemagglutinin (HA) glycoprotein of influenza virus has been investigated. Excellent separation was accomplished with sample recovery of at least 90β95%
