Abstract

A method of measurement for analytical ultracentrifuges with a multi-cell rotor and with simultaneous measurement of several cells, in which light pulses of constant energy are passed, independently of the rotor speed, through individual selectable measuring cells in the entire speed range and in which these light pulses can be provided either by a controlled laser beam or a controlled Kerr cell or a controlled gas discharge lamp.
