Chromatographic Column For Microwave Heating
US Patent:
6029498, Feb 29, 2000
Filed:
Jun 29, 1999
Appl. No.:
9/342368
Inventors:
David L. Walters - Northglenn CO
Scott Gaisford - Denver CO
Scott Gaisford - Denver CO
Assignee:
MT Systems, LLC - Denver CO
International Classification:
G01N 3002
US Classification:
73 2339
Abstract:
A chromatography column for microwave heating either incorporates microwave absorbing material into the column itself or positions the column adjacent to microwave absorbing material so that the column and the chromatography sample contained therein are heated by the microwave absorbing material via conduction or convection. For example, a microwave absorbing material (e. g. , ferrite) can be fused into the inner silica layer or incorporated in an outer polymer layer of the column. Microwave absorbing material can also be incorporated into an external element (e. g. , an outer tube, sleeve, or spool) positioned adjacent to the chromatography column. A layer of thermal insulation can be placed around the column to decrease the rate of heat loss. Optionally, a gap can be provided between the chromatography column and thermal insulation to further reduce heat loss during the heating cycle and to accelerate cooling at the end of the heating cycle by making it possible to ventilate the heated column. The chromatography column assembly can be protected from overheating by selecting a microwave absorbing material having a loss factor that decreases rapidly above a predetermined maximum temperature.
Microwave Heating Apparatus For Gas Chromatographic Columns
US Patent:
6157015, Dec 5, 2000
Filed:
Jul 23, 1999
Appl. No.:
9/359879

MT Systems, LLC - Denver CO
International Classification:
H05B 680, H05B 672, G01N 3002
US Classification:
219748
Abstract:
A microwave heating apparatus is used for heating a chromatographic column assembly containing a microwave absorbing material. The microwave heating apparatus includes an antenna transmitting a microwave signal and a resonant cavity containing the chromatographic column assembly and the antenna. The chromatographic column assembly extends relative to predetermined electromagnetic field strength contours within the resonant cavity to provide a predetermined heating profile along the length of the chromatographic column assembly. For example, a single-mode chromatographic column microwave oven can be used to heat a coiled chromatography column to a desired temperature gradient along its length. Oven design embodiments utilizing coaxial transmission line structures, coaxial resonators, and cylindrical resonators are described. To control the electromagnetic field gradient in the axial direction, the oven designs provide for varying some part of the oven geometry in the axial direction.
