  • Patent number: 9347919
    Abstract: The present invention provides a method and apparatus for rapidly extracting the analyte existing in the liquid phase in analyzing an analyte “having a large partition coefficient in gas-liquid equilibrium”, “having a high water solubility”, or “having a low olfactory threshold” by a gas-liquid contact extraction method, and further provides, a method and apparatus for unmanned continuous sample introduction of the analyte to a GC or the like for a long time. In the present invention, using a gas-liquid contact extractor to which a sample liquid is continuously introduced from above and a purge gas from beneath, the analyte in the sample liquid is extracted by gas-liquid contact between the sample liquid and the purge gas. A discharge pipe is connected to the bottom of the gas-liquid contact extractor, the pipe having a liquid sump through which the sample liquid is discharged, while blocking the outflow of the purge gas from the liquid sump.

  • Patent number: 9021866
    Abstract: A gas-leak detector includes a suction pump that sucks sample gas and reference gas, two gas detection sensors, and a cell block having a cell therein. The cell receives the gasses and has two suction-gas introduction channels and a single gas discharge channel opening thereinto. The gas-leak detector detects a gas leak on the basis of outputs from the sensors. The introduction channels and the discharge channel open into the cell at a first one of opposing surfaces of the cell, the opening of the discharge channel being arranged between the openings of the two introduction channels. The sensors are on the same plane as a second one of the opposing surfaces and are arranged between the opening of the discharge channel and the openings of the introduction channels. The suction pump is arranged on the cell block and communicates with the opening of the discharge channel.

  • Patent number: 8935941
    Abstract: To use a monolithic silica body in chromatography with a HPLC column or a GC column and to simplify the use thereof as a separation medium, it is intended to provide a method of cladding a main body of a monolithic adsorbent or separating agent with glass so as to protect the outer surface, and to provide a separation medium prepared by the method. To this end, a monolithic silica body alone is formed by molding, and the molding is coated with a glass body; and then the glass body and the monolithic silica body are fused and integrated at the melting temperature of the glass body at an appropriate pressure. The surface of the resulting monolithic silica body clad with glass is strongly protected by the glass, and the homogeneity of the interior of the monolithic silica body is maintained, and thus uniform flow of a sample solution ensures analytical accuracy.

  • Patent number: 8795410
    Abstract: The problem to be solved by the present invention is to provide a monolith adsorbent which can adsorb a target sample easily in a short time or regardless of whether the amount of the sample is small or large and extract the sample with a small amount of solvent, and easily secure the sample necessary for analysis, and a method and an apparatus for adsorption and retention using the same. The present invention is a monolith adsorbent formed by allowing a monolith structure body to contain an adsorbing material such as activated carbon or graphite, exposing the adsorbing material on the surface of the structure body and further surface-treating the surface of the monolith structure body with a hydrophobic or hydrophilic compound or a resin.
