Claim One:
1. A method comprising: (a) irradiating a sample comprising at least one unknown particle to thereby produce Raman scattered photons; (b) collecting said Raman scattered photons to thereby generate a Raman chemical image representative of said sample; (c) applying a first threshold to said Raman chemical image wherein said first threshold is such that all particles in said sample are detected; (d) selecting one of said particles detected as a result of applying said first threshold; (e) applying a second threshold to said Raman chemical image to thereby determine at least one geometric property of said selected particle, wherein said second threshold is unique to said selected particle such that said at least one geometric property can be determined; (f) analyzing at least one spectrum representative of said selected particle to thereby classify the selected particle as at least one of: a particle of interest and not a particle of interest.
