Abstract: In an analytical apparatus for analysis of particulate motion in a flow cell, there is provided, for calibration of the analytical apparatus, a movable calibration slide generally disposed to translate into and out of the optical viewing path of the analytical system devoted to calculating particle related information. Appropriately located upon the surface of the slide is a predetermined number of contrast regions representing particles. The slide is translated at a given rate within the optical viewing path and simulates predetermined particle movement for use in calibration of analytical devices for obtaining particle information.

Abstract: In an analytical apparatus for analysis of particulate motion in a flow cell, there is provided, for calibration of the analytical apparatus, a movable and preferably rotatable calibration disc generally disposed within the optical viewing path of the analytical system devoted to calculating particle related information. Appropriately located upon the surface of the disc is a predetermined number of contrast regions representing particles. The disc is rotated at a given rate within the optical viewing path and simulates predetermined particle movement for use in calibration of analytical devices for obtaining particle information.
