Title: The Innovative Contributions of Hans-Rudiger Doring
Introduction
Hans-Rudiger Doring is a notable inventor based in Leipzig, Germany. He has made significant contributions to the field of ion mobility spectrometry, holding a total of 4 patents. His work has advanced the technology used in various analytical applications.
Latest Patents
Doring's latest patents include an "Ion mobility spectrometer with switchable electrodes." This invention relates to a switchable ion mobility spectrometer (IMS) featuring ring electrodes divided into half-rings that surround the drift chamber of the IMS. In the first operating condition, the two half-rings of each ring electrode are at the same potential, while the various ring electrodes are at different potentials, varying monotonously along the drift path. This design allows ions to be transported in the conventional manner along the drift path. In the second operating mode, the half-rings of the ring electrodes are at different potentials, causing the ions to be deflected toward one of the half-rings. The resulting currents are captured by the corresponding half-rings, amplified, and an ion mobility spectrum is produced. This favorable design for the IMS can be utilized in many different modes of operation. Another notable patent is the "Ion mobility spectrometer in a centripetal arrangement," which features electric drift fields directed at a central detector electrode. This IMS is rotationally symmetrical and has a disk shape, enhancing its analytical capabilities.
