Abstract
SEVERAL good methods now exist for observing the sedimentation boundary in the ultracentrifuge. That described here should, however, be useful because it is the least laborious way of producing a ‘sedimentation diagram’ (that is, a curve relating concentration gradient to distance from the axis of rotation). It is probably not so accurate as the ‘scale’ method1, though this question seems worth investigating ; but certainly the accuracy is sufficient for a great many purposes.
