Title: Hendrik Kersten and Atmospheric-Pressure Ionization

Introduction

Hendrik Kersten is an inventor associated with Wuppertal, Germany, and Bruker Daltonik GmbH. His work includes a patent for an atmospheric-pressure ion source designed for use with ion spectrometers operating under vacuum.

Latest Patents

Kersten is credited with 1 patent: “High Yield Atmospheric Pressure Ion Source for Ion Spectrometers in Vacuum.” The invention ionizes gaseous analyte molecules at atmospheric pressure and guides the resulting ions through a reaction tube into an ion spectrometer’s inlet capillary. The tube is shaped to maintain stable laminar gas flow, while a conical intermediate piece provides a gastight, smooth transition to the capillary. Analytes may come from gas chromatographs, spray devices, or vaporization devices, and can be ionized using photon-based, chemical, reactant-ion, or physical methods.

Career Highlights

The patent describes a versatile approach to introducing and ionizing gaseous samples before they enter a vacuum-based ion spectrometer. It also outlines options such as directing a laser beam axially through the reaction tube or generating reactant ions externally and mixing them with analyte molecules inside the tube.

Collaborations

Kersten’s listed coworkers include Jochen Franzen and Thorsten Benter. His company affiliation is Bruker Daltonik GmbH.

Conclusion

Hendrik Kersten’s patent presents an atmospheric-pressure ion-source design that combines controlled gas flow, flexible ionization methods, and a smooth interface with an ion spectrometer’s vacuum inlet.
