ABSTRACT:
This invention pertains to a method and an apparatus for determining concentration of solid particles of interest in a sample in the presence of at least one other type of solid particle by measuring light scatter at a wavelength which is independent of solid particle concentration which is not of interest and related to solid particle concentration of interest. Preferably, solid particles of interest are cells grown in cell culture medium comprising a solid substrate.
