  • Publication number: 20210384881
    Abstract: In a method for determining cleanliness of a cleaning member that contacts a substrate and with which scrub cleaning is performed, the method includes a first step of self-cleaning a cleaning member by releasing contaminants from the cleaning member into a cleaning liquid, and a second step of bringing a self-cleaning discharged liquid into contact with an electrode of a crystal oscillator, attaching the contaminants contained in the discharged liquid onto the electrode of the crystal oscillator, then measuring a frequency response of the crystal oscillator in which the contaminants are attached onto the electrode, and determining cleanliness of the cleaning member based on the measured frequency response.

  • Publication number: 20050254998
    Abstract: A reactive detection chip having spots formed by immobilizing a plurality of porous particles in a cluster onto a substrate, the porous particles having probe molecules bound to surfaces of the porous particles and surfaces of pores in the particles including pores, wherein the porous particles are transparent to incident light, and have been immobilized in a single-layered state onto the substrate, is provided. A spotter suitable for spotting a liquid containing low dispersibility particles in manufacturing the reactive detection chip is also provided. In the reactive detection chip, the number of probes can be stably controlled, and a three-dimensional array of the probes uniformizes the supply of a sample to the probes. Thus, the magnitude of signal components is stabilized, and signal components are stably increased, so that the S/N ratio is increased, and the detection capability of the DNA chip can be enhanced. The use of the spotter enables the chip to be manufactured more efficiently.

  • Patent number: 5950646
    Abstract: A vapor feed supply system including a vaporizer device and a method of cleaning a vapor flow region employing such a vaporizer device enables thorough cleaning of the system, without having to degrade the overall system vacuum in the process of cleaning the vaporizer device. The method includes defining a cleaning fluid passage having a predetermined withstand pressure by isolating a cleaning region of the vapor flow region, and flowing a cleaning fluid into the cleaning fluid passage under a pressure so as to enable the cleaning fluid to remain in a liquid state at a cleaning temperature of the cleaning region.
