Miniaturized pulsed discharge ionization detector, non-radioactive ionization sources, and methods thereof
| DWPI Title: Method for fabricating miniaturized pulsed discharge ionization detector, involves aligning ionization source comprising annular high voltage electrode, and inserting tangs of annular electrodes and high voltage electrode into circuit board |
| Abstract: The present application relates to pulsed discharge ionization detectors (PDIDs) and non-radioactive ionization sources, including miniaturized forms thereof. In some examples, the PDID includes annular electrodes, where each electrode is disposed between annular insulators. Also provided herein are methods of making and using such PDIDs, such as for detecting one or more volatile organic compounds, as well as non-radioactive ionization sources. |
| Use: Method for fabricating a miniaturized pulsed discharge ionization detector. |
| Advantage: The method enables enhancing ability to place an electronic measurement item adjacent to a collector and improving signal-to-noise performance, and achieving miniaturization effect, and effectively replacing a radioactive source and ion gates of an Ion mobility spectrometer (IMS) and similar instruments, avoiding using need of ion gates for IMS and other instruments and facilitating correlation ion mobility spectrometry. |
| Novelty: The method involves aligning a bore of each of annular electrodes and annular insulators (120) to form a chamber (106), where the annular electrodes and the annular insulators are placed alternately. An ionization source comprising an annular high voltage (HV) electrode (111) is aligned, where the annular HV electrode comprises a proximate surface, a distal surface, a tang, and a bore defined through the proximal and distal surfaces. The tangs of the annular electrodes and the annular HV electrode are inserted into a circuit board. An external housing is placed around the annular electrodes, the annular insulators, and the annular HV electrode. |
