Title: Ye Han: Innovator in Halohydrocarbon Detection

Introduction

Ye Han is a notable inventor based in San Jose, California, recognized for his contributions to the field of analytical chemistry. He holds a total of six patents, showcasing his innovative approach to environmental monitoring and detection technologies.

Latest Patents

One of Ye Han's latest patents involves methods and apparatus for the determination of halohydrocarbons in water. This real-time, on-line analytical system operates by extracting on-line samples and purging volatile halohydrocarbons from the water using air or nitrogen. The system carries the purge gas containing the analytes of interest over a porous surface where the analytes are adsorbed. The recovery of the analytes from the porous surface can be achieved through thermal desorption or solvent elution, driving the analytes into an organic chemical mixture. The process generates an optical change, such as a color change, based on a reaction involving the analytes and a pyridine derivative. Finally, the optical characteristics associated with the reaction are measured to quantify the concentration of volatile halogenated hydrocarbons.
