HPLC Analysis of Light Scattering Detection of BSA on Zenix® SEC-300

HPLC Analysis of Light Scattering Detection of BSA on Zenix® SEC-300


column Zenix SEC-300, 30 cm x 7.8 mm I.D., 3 µm particles, 300 Ã… (Z777033)
column temp. 25 °C
mobile phase 0.1M phosphate buffer
flow rate 1.0 mL/min
sample BSA (20mg/mL)
injection 20 µL
detector Hitachi-Elite LaChromL-2130 pump equipped with aµLti-angle light scattering detector (DAWN-HELIOS: Wyatt Technology),a refractive index detector (Hitachi L-2490) and a UV-Vis detector (Hitachi 2420)


Analysis Note The chromatogram shows an overlay of the ultraviolet (UV), differential refractive index (RI) and µLti angle light scattering data (MALS) for a sample of bovine serum albumin; showing the prsenece of dimer and trimer as well as the monomer. The chromatogram illustrates the power of light scattering used with Sepax’s Zenix® SEC in protein characterization. The light scattering data makes it possible to determine the molecular mass for the monomer, dimer and trimer.
