Title: Xinxin Han and a Method for Detecting Trace Nitrosamines.
Introduction
Xinxin Han is an inventor associated with East Brunswick, New Jersey, and Merck Sharp & Dohme LLC. His work includes a patented method for detecting trace levels of semi-volatile nitrosamines in solid samples. His listed portfolio includes 1 patent.
Latest Patents
Han’s patent, “Method for Analyzing Trace Levels of Semi-Volatile Nitrosamines in Solid Samples,” describes a process for preparing a nitrosamine sample and adding chemicals that reduce or eliminate nitrosamine formation during analysis. The method uses full evaporation static headspace gas chromatography coupled with a nitrogen-phosphorus detector (FE-SHSGC-NPD). By analyzing the gaseous phase, it aims to provide rapid, sensitive detection of semi-volatile nitrosamines, including NDMA.
Career Highlights
The available information connects Han’s invention to analytical methods for identifying trace contaminants in solid samples. The approach addresses a key challenge in nitrosamine testing: limiting the formation of nitrosamines during sample preparation so that measured results more accurately reflect the sample.
Collaborations
Han’s listed coworkers include Rebecca Evans and Daniel E. Lee. The provided information does not specify their roles in the patent or their contributions to the invention.
Conclusion
Xinxin Han’s patent describes a rapid analytical approach designed to detect trace semi-volatile nitrosamines while reducing the risk of their formation during testing.
