Title: The Innovations of Shinji Uchiyama
Introduction
Shinji Uchiyama is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of gas analysis technology. With a total of 3 patents, Uchiyama's work focuses on enhancing the efficiency and accuracy of gas chromatographic methods.
Latest Patents
Uchiyama's latest patents include an innovative analysis method and device aimed at increasing the difference between the thermal conductivity of the carrier gas and the thermal conductivity of each component of the sample gas. This analysis method utilizes a gas chromatograph equipped with a thermal conductivity detector. The process involves introducing both a carrier gas and a sample gas into a separation column. The sample gas is then separated and introduced into a gas introduction chamber, where an element with temperature-sensitive electrical characteristics detects changes due to the sample gas. Notably, the method allows for switching the carrier gas from a first type to a second type while the sample gas component passes through the separation column.
Another significant patent involves a discharge ionization current detector and gas chromatograph. This invention features a partition with a through hole for introducing a sample gas, positioned between a collector electrode and an outlet for discharging gas. The design ensures that the plasma-generating gas passes through a gap towards the outlet, while preventing air from entering through the opposite direction.
