Abstract: An apparatus and method to identify at least one component from a plurality of components in a fluid mixture, includes a first input channel containing the fluid mixture of components; at least one buffer input channel, into which at least one additional flow of buffer solution is introduced; a plurality of regions disposed at the other end of the apparatus, which are adapted to receive outputs of at least one selected component of the plurality of components, the selected component which is selectively removed from the first flow to one of the regions; a waste channel through which unselected components are removed from the first flow; a plurality of pumps connected to at least one reservoir, to control flow rates of the first flow and the additional flow(s); and a computer which controls a selection of one of the plurality of components from the fluid mixture.

Abstract: The present invention provides a method and apparatus to identify at least one component from a plurality of components in a fluid mixture, the apparatus including a first input channel into which a first flow containing a plurality of components is introduced; a plurality of buffer input channels, into which additional flows of buffer solution are introduced, disposed on either side of the first input channel; wherein the first flow and the additional flows have a flow direction along a length of the apparatus; a detector apparatus which detects and identifies selected components of the plurality of components; a laser which emits a laser beam which damages or kills selected components of the plurality of components; and at least one channel disposed at the another end of the apparatus which is adapted to receive the first flow and the additional flows after operation of the laser on the selected components.

Abstract: The invention provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

Abstract: An apparatus (10) for analyzing lubricant oils and functional fluids includes an optical emission spectrometer (OES) (26) having a substantially continuously valued wavelength versus intensity output (140). The OES (26) analyzes light captured from a spark emission stand (58) through which the fluid sample is flowed. An expert system (160-172) operates according to a set of Rules, and generates diagnostic text (174) for an operator based on the information about the fluid sample provided by the OES (26) and other measurement devices. The apparatus (10) is reduce in size, weight and cost.
