Title: Jochen Pokar: Innovator in Mass Spectrometry

Introduction

Jochen Pokar is a notable inventor based in Julich, Germany. He has made significant contributions to the field of mass spectrometry, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is for a quadrupole mass spectrometer. This device is enclosed by a high vacuum container and includes an ionization chamber, a molecular beam radiator, and a cryopump. The design features the output opening of the radiator and the cryopump positioned at the periphery of the ionization chamber, preferably diametrically opposite one another. Another patent focuses on an apparatus for measuring the proportion or quantity of a component in a radiation-transparent mixture. In this invention, a beam is passed through the mixture and split into a measuring beam and a reference beam. The measuring beam is filtered through a narrow-band interference filter that corresponds to a discrete absorption wavelength of the component, while the reference beam passes through a different filter. The radiation intensities of both beams are detected separately, and their difference indicates the proportion or quantity of the component.
