DEVICE FOR MEASURING AT potentiometric flow-injection analysis

摘要

The claimed utility model relates to means for the potentiometric determination of various ions in solution at a flow-injection analysis. The technical result of the utility model consists in leveling the flow velocity of the flow through the flow cell Ionometric that ensures no flow oscillations and potential, as a result, increases the accuracy of measurement results. Said technical result is reached by that in an apparatus for potentiometric measurements comprising means sample preparation, flow potentiometric cell and control means and processing the analytical information, according to the claimed utility model, introduced vertically mounted before the flow potentiometric cell flow gap assembly comprising interconnected, monolith made from a polymer, chemically inert material, the base and cover, between which a germeti iruyuschaya gasket, the lid comprising at least one flow channel connected with the sample preparation means, is provided with a protruding element with a flow channel being placed, with the possibility of free dripping flowing therethrough flow analysis sample, a cavity formed in the top of the base, and gradually tapering to the size of the flow channel formed in the base bottom portion and communicated with a flow cell.
