Which light scattering detector is best for me?

Determining which gel permeation/size exclusion chromatography (GPC/SEC) system is best for your needs can be a daunting task. Even after you’ve decided to include a light scattering detector to obtain absolute molecular weight data you’re still left to choose between…READ MORE >

New: Protein Columns for light scattering

Light scattering in chromatography can sometimes be challenging: The scattering signal is proportional to the size to the 6th power, and that is why particles in the mobile phase can lead to noise in the light scattering detector. Now we…READ MORE >

Multi Angle Light Scattering (MALS)

What is multi angle light scattering MALS / MALLS? Light scattering is the effect of light being re-radiated from a sample containing molecules or particles. This scattering depends on the optical configuration of the setup, and in a typical experimental…READ MORE >

Refractive index increment dn/dc values

Refractive index increment dn/dc values when you need them? In light scattering a crucial parameter which appears together with the Rayleigh Ratio RΘ is the refractive index increment, also known as “dn/dc”. Typically Kc/RΘ is plotted versus concentration to extrapolate to…READ MORE >
