Abstract
A measurement accuracy of a particle size distribution measuring device that performs a particle size distribution measurement in a line start mode is improved by a measurement cell used in a line start mode of a centrifugal sedimentation type particle size distribution measuring device that includes a cell main body and a cell cap. The cell main body has an opening provided on one end and stores therein a density gradient liquid WDGS. The cell cap closes the opening of the cell main body and has an internal passage R provided therein for holding a sample liquid WSS. When an application of a centrifugal force is received, the sample liquid WSS is introduced from the internal passage R into the density gradient liquid WDGS.

A measurement cell used in a line start mode of a centrifugal sedimentation type particle size distribution measuring device, the measurement cell comprising:
- a cell main body that has an opening on one end and that stores therein a density gradient liquid that is a solution having a density gradient;
- a cell cap that closes the opening of the cell main body and that is provided with an internal passage for holding a sample liquid, wherein
- the sample liquid held in the internal passage of the cell cap is introduced into the density gradient liquid in the cell body through the internal passage by receiving an application of a centrifugal force.
