Scientific Basis of the Calculator

The Ultracentrifugation Calculator is grounded in the sedimentation principle, which states that denser particles settle faster than less dense ones under centrifugal force. The calculator uses the Svedberg equation to compute the sedimentation coefficient (s):

s = (v / ω²r) / (1 - ρₚ/ρₛ)

Where:

• s = Sedimentation coefficient (in Svedberg units, S)
• v = Velocity of sedimentation (cm/s)
• ω = Angular velocity (rad/s, derived from RPM)
• r = Radial distance from the center of rotation (cm)
• ρₚ = Particle density (g/cm³)
• ρₛ = Solvent density (g/cm³)

The sedimentation coefficient is corrected for solvent viscosity to ensure accuracy. This equation is widely used in analytical ultracentrifugation to characterize macromolecules. The calculator also accounts for standard conditions, ensuring results align with peer-reviewed methodologies.
