  • Patent number: 11130126
    Abstract: There is provided a fluid analysis chamber module that allows an analysis element to be replaced in a sliding manner. The module includes a middle body, an upper body, and a lower body, in which the upper body and the lower body are rotated to be in contact with an upper surface and a lower surface of the middle body and to release from the contact state. The middle body provides a chamber hole where a tray with the analysis element seated thereon can be mounted. The middle body is provided on its front end with a tray receiving opening through which the tray is mounted into the chamber hole. When the upper body and lower body are rotated to be in contact with the upper surface and the lower surface, respectively, the chamber hole is closed, a fluid supplying line and discharging line are sealed, pogo pins for power supply and signal transmission are contacted to electrodes of the analysis element.

  • Patent number: 10551361
    Abstract: Disclosed is a separation column for micro gas chromatography, having superior separation performance and including a microchannel formed on a substrate and having a serpentine shape, and bumps formed on the surface of the microchannel, wherein the bumps are alternately disposed to face each other on the surface of the microchannel. In the separation column for micro gas chromatography, a sufficient pressure drop occurs, and thus an interaction between a gas mixture to be analyzed and a stationary phase in the column sufficiently takes place, whereby individual gas components are efficiently separated from the gas mixture, discharged from the column, and detected.

  • Publication number: 20150368824
    Abstract: Provided are a superhydrophobic/superoleophobic structure and a method of manufacturing the superhydrophobic/superoleophobic structure. The superhydrophobic/superoleophobic structure includes: a roughened primary structure formed on a surface of a metal base; nanopores formed in the roughened primary structure; and a hydrophobic/oleophobic layer formed on a surface of the roughened primary structure. The superhydrophobic/superoleophobic structure makes a large contact angle and a small sliding angle with both aqueous solutions and oily solutions, thereby having a high degree of superhydrophobicity/superoleophobicity. In addition, the superhydrophobic/superoleophobic structure may be formed on large or curved structural objects by the manufacturing method without using a special device.
