Embodiment Construction

[0049] figure 1 A generalized implementation of the invention is shown using schematic diagrams. For example, the device is provided with N probe electrodes for applying a potential in the first normal pressure chamber C1, and the carrier gas is introduced into the first normal pressure chamber C1 through the inlet G1 and flows out through the airtight outlet O1. The electrodes N can be point, line, surface or curved electrodes. A probe electrode is an example of a point electrode, and a trim blade is an example of a wire electrode. Indeed, the presence of multiple probes or other electrodes of the same polarity within the first atmospheric chamber is an arrangement particularly useful for chemical reagent monitors. When multiple electrodes (N) are used, a corresponding increase in detection sensitivity can be observed. The counter electrode E0 contains pores through which gases and charged particles can pass. A potential (for example, ground potential) is set to generate ...

Abstract

A non-radioactive atmospheric pressure apparatus for ionizing an analyte comprising: a first atmospheric pressure chamber having a carrier gas inlet, a first electrode at one end, and a counter electrode at the other end of the chamber for use in generating metastable A discharge is generated in the carrier gas of the sexually excited state substance. Optionally, the grid is configured to generate electrons or ions by contacting the species in an excited state. At normal pressure, near ground potential, a carrier gas containing its generated excited state species or electrons is directed at the analyte to form analyte ions.

Description

[0001] Cross references to related patent applications [0002] This patent application discloses the subject matter disclosed in Provisional Patent Application Serial No. 60 / 460,179, filed April 14, 2003, and claims priority based on 35 U.S.C. §119(e). technical field [0003] The present invention relates to ionization of analytes using metastable atoms and molecules at atmospheric pressure. Metastable atoms and molecules (M * ) is a long-lived excited state substance. During corona discharge or glow discharge, metastable species are produced. Other methods of generating species in an excited state include electron collisions, photoionization, and the controlled interaction of energetic particles and reactants. A collision between an excited state material and a ground state material can result in the ionization of the ground state material and the release of electrons due to a process known as Penning ionization, for example: [0004] m * +N->N + +M+e- Equation 1 ...
