Title: The Innovative Contributions of Dao Hinh Nguyen

Introduction

Dao Hinh Nguyen is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of explosive detection technology, holding a total of six patents. His work focuses on developing advanced systems for identifying both nitrogen-containing and nitrogen-free explosives.

Latest Patents

One of Dao Hinh Nguyen's latest patents is a compact explosive detecting system. This innovative system collects explosive residues in the form of vapor powder. The residues are accumulated on a desorber, which is subjected to pyrolysis to release a gaseous sample. The sample is then pumped to a detecting system through a metering valve. A luminol cell reacts with the gaseous sample to create chemiluminescence, and the light output is measured by a photo multiplier tube. The light intensity indicates the amount of explosive present. Based on this amount, a metering valve is adjusted to pass the gaseous sample into a highly sensitive metal oxide sensor array. This array detects nitrogen oxides from nitrogen-containing explosives and carbon monoxide from non-nitrogen-containing explosives. The metal oxide sensor array reliably selects explosives from those compounds indicating chemiluminescence.
