US 11,959,931 B2 · System and method for dispense characterization

Abstract

A system and method for dispense characterization is disclosed. According to particular embodiments of the dispense characterization system and method, volumes of dispensed liquids can be determined. In more particular embodiments, additional characteristics and combinations of characteristics of a liquid dispensing event can be determined. Examples of additional characteristics that can be determined include the shape of the dispensing event, the velocity of the dispensing event, and the trajectory of the dispensing event. The dispense characterization system and method can be employed in automated biological sample analysis systems, and are particularly suited for monitoring liquid reagent dispensing events that deliver liquid reagents to a surface of a microscope slide holding a biological sample.

Dependent claims

A system for treating a biological sample, comprising:

at least one dispenser for dispensing a liquid reagent;
at least one dispense detector locatable between an outlet of the at least one dispenser and the biological sample, wherein the dispense detector comprises (i) a first array of emitters and a first array of receivers corresponding to the first array of emitters;
and (ii) a second array of emitters and a second array of receivers corresponding to the second array of emitters, wherein the first array of emitters and the second array of receivers are located on a first side of the dispense device, and wherein the second array of emitters and the first array of receivers are located on a second side of the dispense device;
a dispense detection unit configured to receive a signal from the at least one dispense detector during a dispensing event and output a detected dispense event of the liquid reagent from the at least one dispenser.
