A method for isolating a peptide, the method including purification of a GLP-1 peptide from a mixture comprising said peptide and related impurities via a cation exchange chromatography process, the cation exchange chromatography process comprising the steps of: separating said GLP-1 peptide and said related impurities of said mixture by elution in a solution consisting essentially of an organic modifier, water, optionally a salt component, and optionally a buffer, with a linear or step gradient or isocratically in salt component and/or with a linear or step pH-gradient or at a constant pH-value, wherein the pH-gradient or pH-value should be in the range where said peptide has a positive local or overall net charge different from the local or overall positive net charge of said related impurities so as to remove said related impurities
