    Abstract: Method and apparatus wherein a series of fluid samples separated one from another and each segmented in a flowing stream by inert immiscible fluid segments may have such segments optionally removed with the further option of removal of all or some of the segments before the stream passes through a conduit forming at least part of an analysis station, and at which analysis station the flow of such a sample may be stopped.

    Abstract: New and improved automatic dilution apparatus and method are provided, and are operable in conjunction with automated sample liquid analysis systems to automatically dilute sample liquids as supplied thereby to automated sample liquid analysis apparatus. One embodiment of the dilution apparatus operates to dilute the sample liquids by flowing the sample liquids from the analysis system sample liquid supply conduit, diluting the same, and returning the diluted sample liquids to the supply conduit for flow therethrough to the sample analysis apparatus for sample liquid analysis. Flow of undiluted sample liquids through the supply conduit is prevented attendant operation of the dilution apparatus. A second embodiment of the dilution apparatus operates to remove predetermined volumes of the sample liquids from the supply conduit, and to replace the same with like volumes of a diluent liquid; thereby diluting the sample liquids in the supply conduit for continued flow to the sample liquid analysis apparatus. Both embodiments of the dilution apparatus are operable on demand; and the second apparatus embodiment is additionally operable to dilute the sample liquids to a varying degree throughout a predetermined dilution range.

    Abstract: A transport system is provided in which a plurality of samples are introduced into a carrier stream flowing through a conduit, whose inner surface is coated with an immiscible liquid film. The carrier stream can be a sequence of alternating gas and liquid segments which are in direct contact with each other and, thus, not encompassed by the immiscible liquid. Samples are introduced at various points along the conduit and, thus, the system allows for the collection and transport of samples from a plurality of remote locations to at least one central receiving station where they can, for example, be analyzed. Carryover between successive samples to be transported is effectively eliminated.

    Abstract: 1464235 Automatic analysis TECHNICON INSTRUMENTS CORP 5 Feb 1975 [22 March 1974] 4960/75 Heading G1B A fluid sample is analyzed for a constituent of interest by a method comprises passing the sample along a first conduit 20 to a second conduit 36 + 40 or 36 + 42, treating the sample in the second conduit as by introduction of reagent solutions and air segments through lines 26, 32 and 30 respectively to effect a rate reaction of the sample, reversing the flow of the treated sample in the second conduit (part 40 or 42) so that the treatment time before analysis of a trailing portion of the sample entering the second conduit is less than the treatment time before analysis of a leading portion of the sample in the second conduit, and analyzing the sample at an analysis station 54 after the flow in the second conduit is reversed. The second conduit (coil 36) may be temperature controlled. The sample flow is reversed by operation of valve 38, which connects conduit 36 to one of conduit 40 and 42 while admitting sample from the other of conduits 40 and 42 to conduit 52 for analysis at 54. In the embodiment of Fig. 2 (not shown), the remote ends of the second conduit coils are each connected to a T-junction, the arms of each T-junction being connected to a wash liquid supply and to segmenting gas. Segmenting gas in both embodiments may be removed through line 64 before the sample reached the flow cell. Alternatively a bubble detector may be used to detect the presence of a segmenting fluid bubble at 54 and to provide for viewing of the sample only in the absence of a bubble.
