Description
Analysis Note
PAHs are traditionally evaluated using an acetonitrile/water gradient. Recently customers are looking for alternatives to this method using a methanol/water gradient due to the risk of an another acetonitrile shortage, solvent costs, and toxicity to the environment. This analysis demostrates the separation using a methanol gradient.
