Title: Daniel E. Lee: Inventor in Analytical Chemistry
Introduction
Daniel E. Lee is an inventor based in Sayreville, New Jersey, whose patent work addresses the sensitive detection of semi-volatile nitrosamines in solid samples. His invention describes an analytical method designed to reduce the risk of nitrosamines forming during sample preparation and to support rapid detection.
Latest Patents
Lee is associated with 1 patent: “Method for Analyzing Trace Levels of Semi-Volatile Nitrosamines in Solid Samples.” The method involves preparing a nitrosamine sample and adding relevant chemicals to reduce or eliminate in situ nitrosamine formation. It then uses full evaporation static headspace gas chromatography coupled with a nitrogen-phosphorus detector (FE-SHSGC-NPD) to analyze the gaseous phase. The approach is intended to enable sensitive detection of semi-volatile nitrosamines, including NDMA.
Career Highlights
Lee’s patent reflects work on analytical techniques for detecting trace contaminants in solid samples. He is associated with Merck Sharp & Dohme LLC.
