12 Shorter Run Time for Peptide Separation on Proteomix ® SCX NP1.7

Figure 18. Short run time and high resolution for the separation of five Peptides on Proteomix ® SCX NP1.7 2.1 x 30 mm compared to Proteomix ® SCX NP5 4.6 x 100 mm. Mobile phase A: 10 mM phosphate buffer pH 2.5, B: A + 1 M NaCl and C: 100% acetonitrile. Flow rate was 1.0 mL/min (for 5 µm) and 0.6 mL/min (for 1.7 µm). UV detection was set at 214 nm. 2 µL of the peptide mixture was injected.
