Title: The Innovations of Alvin Dorman

Introduction

Alvin Dorman is a notable inventor based in Baltimore, MD (US). He has made significant contributions to the field of ion mobility spectrometry, particularly with his innovative approach to photoionization.

Latest Patents

Dorman holds a patent for a Photoionization Ion Mobility Spectrometer. This advanced device utilizes a flashlamp as the source for ionization. A gas sample is introduced via a carrier gas into an ionization chamber, which is part of the spectrometer cell. Ionizable molecules contained in the injected gas sample are ionized by the ultraviolet light emitted from the flashlamp. The ionized molecules are then attracted by an electrostatic drift field into a drift chamber, where they travel against the flow of a drift gas until they are captured by a collector located in the drift chamber opposite to the ionization chamber. To enhance sensitivity and specificity, a dopant with an effective ionization potential lower than the photon energy of the emitted light can be introduced into the ionization chamber.
