Durability Test by Number of Sample Injections (LW-403 4D)

The durability test for PROTEIN LW-403 4D, an aqueous SEC (GFC) semi-micro column for rapid analysis of antibody proteins, by the number of sample injections was conducted. It is confirmed that the column performance has barely changed after 500 injections.

Sample: 0.5μL
IgG from human serum 10mg/mL
