Abstract: Methods and systems for analyzing ratios of analytes within a flowing sample are provided. The flowing sample can be processed in real-time to determine a time interval over which a predetermined amount of a group of analytes passes by a fixed point in a flow cell. The predetermined amount can be routed to a sample container for future processing. The sample can comprise diluted blood and the analytes can comprise a component of hemoglobin, such as A1c, and the total amount of hemoglobin, of which the predetermined amount is metered.

Abstract: Identification and quantification of constituents of a sample is achieved by mobility-based electropherograms obtained from capillary electrophoresis, the mobilities being normalized by zero correction followed by division by the mobility of a selected marker. Zero correction is achieved either relative to a separate marker or by calculation based on the same marker. The resulting electropherograms are more recognizable since they more closely resemble the scanned separation patterns obtained with planar gels, and individual constituents of the sample are more easily and reliably identified since their positions in the electropherogram are substantially constant from one electropherogram to the next and hence reproducible to a high degree of accuracy.

Abstract: Identification and quantification of paraproteins in a sample is achieved by Fourier analysis of mobility-based electropherograms obtained from capillary electrophoresis. The use of a computer algorithm to analyze capillary electrophoresis data, provides the clinician with methods of detecting levels of paraproteins in serum as low as 0.05 g/dL. Additionally, an individual paraprotein can be located on an electropherogram and used to monitor its increased or decreased production in an individual.

Abstract: Method and apparatus for compensating for the deficiency in fluid flow occurring during the refill and piston chamber pump-up cycle of a single piston fluid pump are disclosed. The period of time during which the outlet valve is closed and no fluid is being delivered to the system is determined and the pump is driven at a speed greater than the normal delivery speed for a period of time such that the quantity of excess fluid delivered approximates the quantity of fluid that would have been delivered during the refill and pump-up period had the pump been delivering fluid at its normal delivery rate.

Abstract: A method and apparatus for deep depletion read-out of data stored in a metal-insulator-semiconductor-metal capacitor memory element wherein a predetermined read-out potential is established across the memory capacitor while discrete storage sites within the capacitor are interrogated by a scanning electron beam probe and the magnitude of the resultant memory capacitor discharge current obtained from probing a particular site with the electron beam is indicative of the character of data stored at the site. The improvement comprises applying a voltage step across the capacitor memory element just prior to read-out with the electron beam, the voltage step corresponding in polarity to the polarity of the majority carriers in the semiconductor.
