Centrifuge at 10,000 rcf in an eppendorf vial and keep the supernatant to remove any large particular matter.Dissolve your biopolymers or small molecules in a suitable solvent such as methanol.Since HPLC is a very machine-variable technique, I can only provide general guidelines. If using UV or FLD, you need to set the right excitation/emission wavelengths For more resolution, run slower.ĭetermines signal intensity, how quickly the peaks come out, signal fidelityĭetermines the type of interaction with the sample With fast flow peaks come out sooner but there’s they’re harder to resolve and tend to blend together. ![]() In a typical HPLC procedure you can decide the following variables: I only use autosamplers since manual injection is tedious □ This means that hydrophobic molecules will stick to the resin more and be retained longer.Ĭomplete Step by Step HPLC guide Materials The buffer that is running through the system is polar (such as acetonitrile/water or methanol/water mixtures).
