Centrifugation time. Calculate the centrifugation time, tc, necessary to remove particles from solution greater than approximately 0.5 μm (5 × 10¥5 μm) equivalent diameter (which represents all particles except the fine clay fraction) using the following equa- tion: tc(min) = 1.41 × 109 [log(R2/R1)]/N2 where: tc = centrifuge time in minutes R2 = distance from centrifuge spindle to dep- osition surface of centrifuge R1 = distance from spindle to surface of the sample N = number of revolutions of the centrifuge per minute.
