In this example, we were able to transfer a complex peptide mapping method from an HPLC instrument and achieve nearly identical chromatography on a UPLC instrument by making one simple ...

For example, on HPLC columns, it is not possible to separate most ionic analytes. This means that HPLC is not suitable for analyses of standard cations or anions in various foods and water.
