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.
Claims7
A method of fabricating a miniaturized pulsed discharge ionization detector comprising:
- aligning a bore of each of annular electrodes and annular insulators to form a chamber, wherein the annular electrodes and the annular insulators are placed alternately;
- aligning an ionization source comprising an annular high voltage (HV) electrode, wherein the annular HV electrode comprises a proximate face, a distal face, a tang, and a bore defined therethrough the proximal and distal faces;
- and
- inserting the tangs of the annular electrodes and the annular HV electrode into a circuit board.
