The second system is semi-preparative/analytical HPLC, primarily targeted at final steps in macromolecular complex purification and characterization. It is equipped with a refridgerated autosampler and a clean enclosed tray fraction collector. In addition, multiple angle laser light scattering detector (Wyatt Te

II) with dynamic light scattering option (DLS) and refractive index detector (Wyatt Technologies TRex) are available in the flowpath for precise characterization of mass and hydrodynamic shape of complexes ranging from 1 nm to 500 nm in size. Native mass analysis using integrated multiwavelength UV/VIS detector enables analysis of complex subunit stoichio
metries, e.g. ribonucleoproteins and multisubunit enzymes or photosynthetic complexes.
