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 |

20130164848 | CELL CULTURE CONTAINER AND CELL CULTURE METHOD USING THE CONTAINER - A well has a pair of side surfaces, and one of the side surfaces is in contact with a compartment of a first channel with a gas-permeable membrane being interposed therebetween and the other side surface is in contact with a compartment of a second channel with a gas-permeable membrane being interposed therebetween. The well is filled with a liquid cell culture medium, and in such a state, a high-concentration gas and a low-concentration gas, which are different in the concentration of a specific component from each other, are allowed to flow through the first and second channels, respectively, to form a concentration distribution of the specific component in the well. | 06-27-2013 |
20150233872 | FLOW CHANNEL MODULE AND CHROMATOGRAPH PROVIDED WITH THE FLOW CHANNEL MODULE - A flow channel module comprises a flow channel plate, a flow channel connection block, and a pressing mechanism. The flow channel plate is provided with a main body and a protrusion section protruding in the circumferential direction from the peripheral edge of the main body, the protrusion section having a port communicating with an inner flow channel. The flow channel connection block is provided with a concave section for being engaged with the protrusion section and having inside a port facing surface for facing the port, and an outer flow channel connection section that is connected to the port facing surface by a flow channel. The pressing mechanism is configured to press the protrusion section inserted in the concave section and the port facing surface against each other so that the flow channel and the port are connected while maintaining air tightness or liquid tightness. | 08-20-2015 |
