Title: Innovations in Gas Detection by Xuejun Zhang
Introduction
Xuejun Zhang is a prominent inventor based in Guangzhou, China. He has made significant contributions to the field of gas detection technology. With a total of 3 patents, his work focuses on developing advanced sensing apparatuses that enhance the detection of various target gas molecules.
Latest Patents
Xuejun Zhang's latest patents include an "Apparatus, system and method for gas detection" and a "fiber optic sensing apparatus, system, and method of use thereof." The first patent describes a sensing apparatus designed to detect at least one target molecule in a gaseous medium. This apparatus features an optical fiber with a core that has a tilted grating and a coating assembly. The coating assembly contains a composite film layer that interacts with the gaseous medium and includes compositions that are responsive to target molecules such as hydrogen, ammonia, methane, and formaldehyde. This innovative design allows for a relatively fast response time and high resistance to deactivation.
The second patent focuses on a sensing apparatus that enables selective detection of target molecules in a gaseous medium with a limit of detection of less than 50 ppm. This apparatus also utilizes an optical fiber with a tilted grating and a coating assembly that is active to surface plasmon resonance (SPR). The system allows for repeated detection and provides a linear measurement range for the target molecule concentrations.
