Abstract
A photometric analyzer and method are disclosed for analyzing particle containing samples. More particularly, a nephelometric apparatus and method are disclosed for analyzing baceteria samples. In the disclosed embodiment, the bacteria count of a bacteria sample is determined by photometrically comparing the sample to another sample having a known particle or bacteria concentration. Thus, in accordance with the invention, samples having a known bacteria count may be quickly and easily obtained from a 'go' 'no-go' test. The bacteria samples obtained according to the invention may be used as standardized bacteria concentrations for conducting Kirby-Bauer dilution tests.
