Title: Huan Yuan: Innovator in Micro Gas Chromatography

Introduction

Huan Yuan is a prominent inventor based in Sichuan, China, known for his contributions to the field of micro gas chromatography. With a total of two patents to his name, he has made significant advancements in the design and functionality of gas chromatography columns and preconcentrators.

Latest Patents

Huan Yuan's latest patents include the development of a wavy micro gas chromatography column and a double-sided diaphragm micro gas-preconcentrator. The wavy micro gas chromatography column features a silicon substrate with a bonded glass cover. It incorporates a micro channel with a rectangular cross-section that is etched on the silicon substrate and coated with a stationary phase film. The design includes multiple regular wavy curves, which enhance flow uniformity and improve separation performance compared to traditional straight channel columns. Additionally, the wavy channel allows for a longer column length within a given area.

The double-sided diaphragm micro gas-preconcentrator is another innovative creation by Huan Yuan. This device consists of a micro-gas chamber formed by stacking upper and lower silicon substrates in a back-on-face configuration. Each substrate has one or more suspended membranes, with a thin-film heater deposited on every membrane. This design improves the area of the sorptive film, resulting in an enhanced preconcentrating factor while maintaining low power consumption and fast heating rates.
