Molecular weight estimated from kinetic experiments 1 medium and 2 particle or droplet

1 Molecular weight estimated from kinetic experiments (1 = medium and 2 = particle or droplet) 

Gravitational experiments can also use the sedimentation equilibrium principle (equating sedimentation and diffusion fluxes). The molecular weight is then given by the equation  

As stated by Shaw (1992), care must be taken to ensure that the system under investigation remains uncoagulated. This applies to any technique used to determine molecular or particle masses.
