Title: Innovations of Dong Qiu in Micro Gas-Preconcentration Technology
Introduction
Dong Qiu is a notable inventor based in Sichuan, China. He has made significant contributions to the field of micro gas-preconcentration technology. With a total of two patents to his name, his work focuses on enhancing the efficiency and effectiveness of gas-preconcentrators.
Latest Patents
Dong Qiu's latest patents include the "Double-sided diaphragm micro gas-preconcentrator with a back-on-face configuration." This innovative device features a micro-gas chamber formed by stacking an upper silicon substrate with a lower silicon substrate. Each silicon substrate is equipped with one or more suspended membranes. The silicon beneath the suspended membranes is completely removed to create a cavity. A thin-film heater is deposited on each suspended membrane, and a sorptive film is coated on the inner wall of every suspended membrane. This design allows for improved area coverage of the sorptive film on the diaphragm, enhancing the preconcentrating factor while maintaining small heat capacity, fast heating rates, and low power consumption.
Another patent is the "Double-sided diaphragm micro gas-preconcentrator," which shares similar features with the previous invention. It also consists of a micro-gas chamber formed by bonding an upper silicon substrate with a lower silicon substrate. The design includes suspended membranes and a thin-film heater, ensuring that the preconcentrator remains efficient and effective in its function.
