Research news: impurity profiling and identity confirmation
Published research has reported refined approaches to profiling synthesis-related impurities in peptide material, including orthogonal separation and high-resolution mass confirmation.
Impurity profiling literature describes orthogonal chromatography — pairing separation modes with different retention mechanisms — as a way to reveal impurities that co-elute under a single method.
Investigators have reported that high-resolution mass measurement helps distinguish deletion sequences, oxidation products and counter-ion artefacts that appear at similar retention times.
The practical conclusion drawn in this literature is that a purity figure should always be read together with the method that produced it.
