Abstract:
A flow cell system for solubility testing of a compound in a sample liquid, comprising:(a) a flow cell suitable for channeling a fluid sheath flowing through the flow cell, the fluid sheath directing a continuous or intermittent sample liquid stream, wherein the sample liquid stream comprises particles of the compound for solubility testing; (b) a light source for illuminating the sample liquid stream in the flow cell and producing scattered light flashes from the particles of the compound; (c) a detector for detecting the scattered light flashes and generating an electronic pulse detection signal for each light flash to provide raw sample data, each light flash having a light intensity and each electronic pulse detection signal having a pulse amplitude corresponding to the intensity of the detected light flash; and (d) a processor for real-time processing of multiple electronic pulse detection signals from said detector, wherein each of the signals is allocated to one of a series of channels, each channel detecting electronic pulse detection signals within a preset signal amplitude range, to provide multichannel sample data, and outputting the sample data for effectuating selection of a subsequent sample liquid from a plurality of subsequent sample liquids for solubility testing.
