Latest Patents

One of Shinden's latest patents is a mass spectrometer designed for analyzing ultra-trace elements using a plasma ion source. This device includes a plasma generating means for ionizing sampling gas, a vacuum chamber for capturing ions, an ion lens, and a mass analyzing portion. Additionally, it features an ion detector that identifies ions passing through the system. A unique aspect of this invention is its moving mechanism, which adjusts the plasma generating means based on the vacuum degree measured in the chamber, enhancing the mass spectrometer's sensitivity.

Another significant patent is the fluorescence polarization analyzer. This device involves adding a fluorescent dye to a sample containing lymphatic cells stimulated by antibodies to measure fluorescence polarization. The polarization changes over time, and the measurement is halted after a predetermined duration. The lymphatic cells are then separated from the sample through filtering. To determine the fluorescence polarization during this filtering process, approximate equations are established based on the measured polarization, improving the reliability of the resulting data.
