Analytical ultracentrifugation is used for the determination of molecules masses in solution.
The instrument analyzes macromolecular sedimentation over a wide range of conditions such as concentration, temperature, ionic strength and pH.
Sedimentation velocity and sedimentation equilibrium experiments can be done with the instrument.
The operating methodology measures the relative change in the distribution of molecular weights, providing an efficient way to measure heterogeneity, stoichiometry and self-associating systems.
The XL-A/XL-I's measurements are based on the first principles of thermodynamics and hydrodynamics, no standards or calibrations are required.
