Pulsed Ultraviolet Ion Source

View page
US Patent:
20090272896, Nov 5, 2009
Filed:
May 5, 2008
Appl. No.:
12/151273
Inventors:
Vladimir V. Belyakov - Podolsk, RU
Vladimir Kekukh - Chestnut Hill MA, US
Anatoly Lazarevich - Lynn MA, US
Stephen N. Bunker - Wakefield MA, US
International Classification:
H01J 49/00
US Classification:
250286
Abstract:
A system and method for providing a pulsed atmospheric source of ions for chemical analysis includes a chamber containing a pair of electrodes and a second chamber with the sample gas. A narrow pulse of high voltage is applied between the electrodes to form an arc which emits ultraviolet light directly into the sample gas chamber through an aperture connecting the chambers. The ultraviolet photons ionize the sample gas and the resultant sample gas ions are then swept into a chemical detector by an electric field.

Chemical Trace Detection System

US Patent:
20220276202, Sep 1, 2022
Filed:
Apr 25, 2022
Appl. No.:
17/727969
Inventors:
- Tewksbury MA, US
Troy Velazquez - Salem NH, US
Anatoly Lazarevich - Needham MA, US
Dmitriy Ivashin - Peabody MA, US
Andrew Anderson - Westford MA, US
International Classification:
G01N 27/622
G01N 27/68
H01J 49/00
G01N 27/626
Abstract:
A chemical trace detection system includes: a drift tube; a detector disposed within the drift tube; a voltage source to produce an electrical field in the drift tube; an ionizer to establish an ionization region adjacent to the electrical field; and a desorber including a sample holder to hold a sample in or adjacent to the ionization region and a sample heater to desorb particles of the sample held in the sample holder such that the desorbed particles are introduced directly into the ionization region from the sample holder to form ionized particles that are forced toward the detector by the electrical field. A regenerable dryer assembly for supplying dry drift gas to an ion mobility spectrometer is also provided that includes a regenerable dessicant material.
