The sample solvent can have a big impact on peak shape in both reversed-phase and HILIC separations, especially when large volumes are injected. Diluting the sample with weak solvent can be an effective solution to mitigate this problem, but we have to be careful to not lose analytes of interest to precipitation or phase separation.

GC CONNECTIONS
