Classification: CPC G  C | IPC C  G

Claim 12:
13. The method of claim 9, wherein
in the interrogating the sample step b):
the at least one fluorescent dye further includes a second fluorescent dye that stains a physical property of the non-proteinaceous material in a manner that distinguishes a non-proteinaceous material having the physical property from a non-proteinaceous material not having the physical property, and the interrogation includes one or more wavelengths that can excite the second fluorescent dye; and

in the collection data step c):
collecting data further includes collecting data from a third fluorescence parameter, the third fluorescence parameter representing presence of the non-proteinaceous material having the physical property based upon fluorescence intensity emitted from the second fluorescent dye; and

in the data analysis step d):
further comprises analyzing the data to define presence of the physical property in order to determine a fraction of counted, sized non-proteinaceous subvisible particles with or without the physical property, thereby characterizing the population of subvisible particles in the sample.
