Patent number: 10725006Abstract: Methods and apparatus for monitoring air samples for the presence of the explosive TATP are disclosed. A preferred approach employs proton transfer reaction mass spectrometry PTR-MS). The system may be operated continuously on a real time or near real time basis. A delivery tube of specific dimensions and materials is employed to introduce the sample into the ionization chamber which in turn generates the ions which are delivered to the mass spectrometer for determining the m/z values. The system may employ a plurality of ionization chambers to reduce the amount of false negative identifiers. A multiple inlet ion funnel may be employed to combine the ions from each of the ionization chambers. Chemical ionization may be employed. A validation module may be employed to reduce the amount of false positive identifiers.Type: GrantFiled: February 26, 2018Date of Patent: July 28, 2020Assignee: RJ LEE GROUP, INC.Inventors: Heinz J. Huber, Richard J. Lee

Patent number: 9291611Abstract: A method for quantitative analysis of asbestos in vermiculite-containing materials includes a first embodiment which includes washing the sample with water or treating the sample with a low concentration acid to digest gypsum and carbonates, ashing the sample at a low temperature to remove cellulose, therefrom and analyzing the sample. Digestion may be effected before or after ashing. Subsequently, a second subsample may be ashed at low temperature to remove cellulose and refluxed with a concentrated acid followed by refluxing with a base and rinsing with deionized water to wash away gypsum, vermiculite and other soluble components. This is followed by analysis to determine asbestos concentration. In a further embodiment, the residue of the first embodiment may be employed as the second subsample.Type: GrantFiled: June 14, 2013Date of Patent: March 22, 2016Assignee: RJ LEE GROUP, INC.Inventors: Richard J.

Patent number: 7341646Abstract: A low energy method of pyrolysis of rubber or other hydrocarbon material is provided. The hydrocarbon material is heated while maintaining a vacuum, using a clay catalyst. In an additional embodiment, also under a vacuum and optionally with or without the catalyst, the temperature of the reaction chamber and corresponding fuel input is varied either over time or spatially within the reaction chamber, to take advantage of the exothermic properties of the reaction. With the method of the present invention, an improved solid reaction product can be achieved.Type: GrantFiled: December 17, 2004Date of Patent: March 11, 2008Assignee: RJ Lee Group, Inc.Inventors: Ronald E.
