Title: Yasuo Seto: Innovator in Gas Monitoring Technology
Introduction
Yasuo Seto is a prominent inventor based in Kashiwa, Japan. He has made significant contributions to the field of gas monitoring technology, holding a total of five patents. His work focuses on developing advanced apparatuses for detecting and analyzing various gases, including those related to chemical warfare.
Latest Patents
One of Yasuo Seto's latest inventions is a gas monitoring apparatus that includes several key components. This apparatus features a sample introducing portion, a measurement portion, an ionization portion, a mass analysis portion, a data processing portion, and a display. The sample introducing portion is designed to introduce a sample gas containing the object material to be measured. The measurement portion is responsible for measuring the concentration of a predetermined coexisting material that exists alongside the object material in the sample gas. The ionization portion ionizes the sample gas, while the mass analysis portion analyzes the mass of the ions produced. The data processing portion then analyzes the signals detected by the mass analysis portion to calculate the concentration of the object material. Additionally, the display presents the results of the analysis conducted by the data processing portion. Notably, the data processing portion includes an adjustment feature that modifies the concentration of the object material based on the concentration of the predetermined coexisting material.
Another significant patent involves a gas monitoring apparatus capable of real-time detection of chemical warfare agents, specifically diphenylcyanoarsine (DC) and diphenylchloroarsine (DA). This invention utilizes atmospheric pressure chemical ionization mass spectrometry in positive ionization mode. The total amount of DC and DA is determined from the intensity of a common ion, while the concentration of DC is derived from a specific ion. The difference between these values is used to ascertain the concentration of DA.
