Gas Discharge Lamp With Built-In Resistance To Color Center Formation In Ultraviolet-Transmissive Window
US Patent:
4801841, Jan 31, 1989
Filed:
Mar 18, 1988
Appl. No.:
7/171182
Inventors:
John N. Driscoll - Wellesley MA
Assignee:
HNU Systems, Inc. - Newton MA
International Classification:
H01J 61067, H01J 6110, H01J 6140
US Classification:
313112
Abstract:
A gas discharge lamp for emitting vacuum UV radiation, comprising a lamp body filled at low pressure with a gas capable of emitting radiation in the vacuum UV range (e. g. , argon), electrodes within the lamp body for passing an electric field across the gas, a crystalline window (e. g. , lithium fluoride) in the body for transmitting the vacuum UV radiation emitted by the gas, wherein the crystalline window is constructed of a material that, when exposed to the vacuum UV radiation emitted by the gas, forms color centers that block transmission of the radiation through the window, and a bleaching element located within the lamp body for emitting color-center bleaching radiation in response to the electric field degrading emission of the vacuum UV radiation, the bleaching radiation being in a frequency band (e. g. , 5-6 eV) lower than the vacuum UV radiation.

US Classification:
204 1T
Abstract:
A method for determining nitrogen oxides in gaseous or liquid samples is disclosed. A semi-permeable membrane- type sensor comprising a sensor electrode, reference electrode and an electrolyte having a pH range of 6. 8-8. 0 or 8. 0-9. 2 is used. Potential between the electrodes is monitored as a measure of nitrogen oxides in the sample. When an electrolyte having a pH range of 8. 0-9. 2 is used the electrolyte additionally contains at least 25% v/v of a water miscible solvent having a dielectric constant of at least 10.

Abstract:
A method is disclosed for determining carbon dioxide content in gaseous or liquid samples. A semi-permeable membrane-type sensor comprising a sensor electrode, reference electrode and an electrolyte having a pH range of 9. 5-11. 0 or 10. 7-12. 0 is used. Potential between the electrodes is monitored as a measure of carbon dioxide in the sample.

Edwards S. Atwood - Natick MA
Assignee:
HNU Systems, Inc. - Newton MA
International Classification:
G01N 2730, G01N 2756
US Classification:
204 1T
Abstract:
A method of determining ammonia in a gaseous or liquid sample is disclosed. A sensor comprising a sensing electrode, a reference electrode, a semi-permeable membrane and an electrolyte is used. The electrolyte is buffered to a pH value between 4. 5 and 6. 5 and is initially free of any salt capable of dissociating to form therein ammonium ion. The electrolyte may optionally contain at least 25% v/v of a water miscible solvent having a dielectric constant of at least 10. In the latter case the pH of the electrolyte is between 5. 5 and 7. 5. The potential between the sensing electrode and reference electrode is monitored as a measure of ammonia in the sample.

Photodiode
US Patent:
4614871, Sep 30, 1986
Filed:
Oct 31, 1984
Appl. No.:
6/666990
Inventors:
John N. Driscoll - Wellesley Hills MA
International Classification:
H01J 4016, G01N 2133
US Classification:
250372
Abstract:
A non-evacuated photodiode for detecting far-uv radiation. The photocathode is a cylindrical element surrounded by an annular anode. The photocathode is constructed of a metal (e. g. , nickel) that emits electrons only in response to far-uv radiation of 140 nanometer or shorter wavelengths. A window (e. g. , magnesium fluoride) is positioned at the entrance to the photodiode, to filter out far-uv radiation with wavelengths shorter than about 100 nanometers. The window and photocathode material serve to make the photodiode sensitive to radiation in a wavelength range to greater than 100 to 140 nanometers. A high-temperature perfluoroethylene material is used as an insulating layer for spacing the window from the anode and for spacing the anode from the photocathode. The photodiode is used in a gas chromatography detector.
