20090004061 | APPARATUS FOR MEASUREMENT OF TOTAL ORGANIC CARBON CONTENT - Disclosed is a total organic carbon (TOC) measurement apparatus capable of facilitating reduction in size of the apparatus and achieving enhanced measurement accuracy. The TOC measurement apparatus includes an organics oxidation unit, a carbon-dioxide separation unit and a conductivity measurement unit, which are integrally formed by laminating a plurality of plates to define therebetween and incorporate therein an oxidizing flow passage, an aqueous-sample flow passage, a gas permeable membrane, a measurement-water flow passage and a conductivity measuring electrode. The TOC measurement apparatus is designed such that carbon oxide in an aqueous sample is transferred from the aqueous-sample flow passage to the measurement-water flow passage through the gas permeable membrane, and a conductivity of measurement water which contains the carbon oxide and flows through a flow passage facing the conductivity measuring electrode is determined and converted to a TOC content. | 01-01-2009 |

20120039749 | PRESSURIZED GAS PURGE SEAL FOR COMBUSTION FURNACE - An analytical combustion furnace has an input port for receiving a holder for an analytical sample. A purge block is coupled to the input port of the combustion furnace and has an input end for receiving the holder and a gas inlet and a gas outlet. A door selectively closes the input end of the purge block, and a pressurized seal is coupled between the purge block and the door. A source of purging gas is coupled to the gas inlet of the purge block for pressurizing the seal. The gas outlet of the purge block communicates with the seal to allow purging gas to escape the area of the seal. In one embodiment, a pressurized seal surrounds a push rod, which seal is pressurized by a purging gas to continuously purge the entry of the push rod into the purge block, thereby eliminating atmospheric contamination. | 02-16-2012 |
