Abstract:
A method of flow cytometry sample processing, comprising the steps of:a. establishing a sheath fluid; b. injecting a sample into said sheath fluid at an injection point; c. subjecting said sample to a first axial motion surface in a nozzle; d. positioning to a second axial motion surface in said nozzle; e. subjecting said sample to said second axial motion surface in said nozzle wherein said first and said second axial motion surfaces transition with a maximal acceleration differentiation; f. coordinating said maximal acceleration differentiation so as to not exceed the practical capabilities of said sample over its length; g. affirmatively limiting said maximal acceleration differentiation so as to not exceed the practical capabilities of said sample over its length; h. exiting said sample from said nozzle; i. analyzing said sample.
