  • Patent number: 8231842
    Abstract: A positive displacement pump (1) is equipped with a pump cylinder (2), a pump piston (7), a cylinder space (9), a pressure sensor (10), and a pressure channel (12). A main portion (13) of the pressure channel (12) extends parallel to a longitudinal axis (3) of the pump cylinder (2), for providing fluidic connection between the cylinder space (9) and the pressure sensor (10). In the improved alternative positive displacement pump (1), the main portion (13) of the pressure channel (12) is located inside of the pump cylinder (2) or pump piston (7) and extends, at least in a foremost position of the pump piston (7), from a cylinder bottom (5) beyond or to an opening (11,11?) in the cylinder wall (4) or pump piston (7).

  • Publication number: 20070141720
    Abstract: In one embodiment, a matrix elimination apparatus for eliminating an acidic matrix includes: at least one column packed with a weak anion exchange resin; a source of samples, each sample having an acidic matrix; a basic solution source; a weakly acidic metal complexing reagent source, and an at least one pump, wherein the matrix elimination apparatus is configured such that the at least one pump can sequence through the acts of: a) pumping the basic solution through the column to regenerate the column, b) pumping the weakly acid metal complexing reagent through the column to activate the column; and c) pumping one of the samples through the activated column to provide a processed sample whose acidic matrix is eliminated.

  • Publication number: 20070098598
    Abstract: A system and method for fluid dilution is provided, in one example to be used in conjunction with a chemical analysis tool. In one embodiment, a fluid dilution system includes a supply reservoir including a concentrated fluid, a diluent source including a diluent, and a diluted fluid reservoir operably coupled to the supply reservoir and the diluent source. A fluid level sensor is operably coupled to the diluted fluid reservoir, a pump is operably coupled between the supply reservoir and the diluted fluid reservoir, and a controller is configured to engage the pump based upon signals from the fluid level sensor to pump desired amounts of the concentrated fluid for providing a diluted fluid in the diluted fluid reservoir.
