How MALS Works

Multi-Angle Light Scattering (MALS) determines absolute molecular weight and molecular size without relying on calibration standards.


⇢  Light scatters increasingly forward as molecular weight increases
⇢  Differences in scattering intensity at multiple angles determine molecular size (Rg)
⇢  Combined with SEC, MALS provides additional structural and compositional insight into eluting peaks
