Abstract

An improvement in a system that identifies unknown microscopic particles in a fluid such as water, by detecting scattering of a laser beam (24) in multiple directions as a particle passes through a detect zone (30) to generate an event vector, and by comparing the eventvector to those of particles of known species. When the eventvectors produce a cluster (70) of particles in a multi-dimensional projection of the eventvectors, the computer signals that a possible new species has been found in the fluid. A background signature is generated for particles in the fluid when the fluid is safe. When new water is later passed through the apparatus, clusters of particles are searched for that are present in a much greater density than exists for the background signature for a safe fluid, to generate a signal indicating that the fluid may be unsafe.
