  • Total organic carbon analysis
    Patent number: 8679408
    Abstract: The present invention provides an apparatus and method for measuring carbon (any one or all of TC, TOC, or TIC) in a sample matrix. In an embodiment, a method for measuring carbon in a sample composition is provided. The method comprises providing an apparatus comprising a reaction chamber and a diamond coated electrode, wherein the diamond coated electrode is doped with boron. The apparatus further comprises a detector. In addition, the method comprises contacting the sample composition with the electrode. The method further comprises applying an alternating current to the electrode at a sufficient voltage to produce carbon dioxide. Moreover, the method comprises measuring the amount of carbon dioxide produced.
    Type: Grant

  • Diaphragm valve for cryogenic applications
    Patent number: 5762314
    Abstract: A diaphragm valve for use with cryogenic systems controls the flow of cryogen and is capable of operating at high pressures for extended periods of time. The diaphragm consists of a polyamide film sandwiched between to manifold sections. A pilot valve controls the pressure of cryogen against one face of the diaphragm to open and close the diaphragm.

  • Permeation pH control system
    Patent number: 4917709
    Abstract: A simplified, single component resin bed is coupled with a permeation tube and bottle. The permeation bottle contains an ionic species and a dissolved gas. The apparatus makes unnecessary a multi-component resin ion exchange column for solvent pH control in electrolytic conductivity detection as applied to gas chromatography.
