Abstract: A method for detecting and identifying a particle in a liquid, the system comprises controlling the provisioning of a water sample using a computer controlled metering pump; mixing the water sample with particle free filtered water to provide a diluted water sample when required; at the end of a measurement interval, determining a Total Counts Per Minute (TCPM) for the diluted water sample; determining an additional counts per minute from the sample (SCPM) for the diluted water sample; if the SCPM is greater then a Lower Optimum count Rate (LOCR) and less than a Upper Optimum Count Rate (UOCR), then setting a dilution ratio (DR); and correcting an events classification based on the DR.

Abstract: A particle detection system uses a camera to produce a picture based on the scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. These pictures are then automatically analyzed through the use of a processing system (e.g., a computer). The processing system is configured to record the forward scattering intensity (e.g., amplitude) and the picture of the scattered light rays to generate a classification of the particle causing the scattering. Count rate and trends of the classified particles are monitored to detect a change that is representative of the overall health safety of the water or by knowing the levels of bacteria in process water, such as Reverse Osmosis (RO) feed water, reject brine, and product water, the operator may better monitor the life and condition of the RO membrane.

Abstract: A particle detection system to identify and classify particles is programmed to capture digitized images of the particle generated by directing a light source through a fluid that includes the particle. The particle scatters the light and the scattered light is detected using a detector. The detector creates a digital signal corresponding to the particle, which is used by the system to generate Bio-Optical Signature. This Bio-Optical Signature can then be used to classify the event, or particle. Count rate and trends of the classified particles are monitored to detect a change that is representative of the overall health safety of the water or by knowing the levels of bacteria in process water, such as Reverse Osmosis (RO) feed water, reject brine, and product water, the operator may better monitor the life and condition of the RO membrane.

Abstract: A particle detection system uses a reflective optic comprising a curved surface to detect high angle scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. When the particles transit the laser beam, light is scattered in all directions and is described by MIE scattering theory for particles about the size of the wavelength of light and larger or Rayleigh Scattering when the particles are smaller than the wavelength of light. By using the reflective optic, the scattered light can be detected over angles that are greater than normally obtainable.

Abstract: A sample analysis system comprises a laser unit and a spectrometer unit. The laser unit emits a first laser pulse and a second laser pulse towards the sample with a pulse separation time of between about 1 microsecond to 20 microseconds. The laser unit includes an oscillator unit which is configured to generate the first laser pulse and the second laser pulse. A pre-amplifier unit is configured to receive the first laser pulse and the second laser pulse and increase the energy levels of each pulse prior to the pulses being emitted from the laser unit. The spectrometer unit captures emissions generated by the sample after the sample is stuck by the first and second laser pulses and identifies the elemental constituents of the sample using the emissions.
