    摘要： A method and associated instrument are disclosed for increasing the sequential rate at which a series of microwave assisted chemical reactions that potentially generate high pressure can be carried out. The method includes the steps of opening a pressure-resistant valve on a microwave-transparent pressure-resistant vessel to define a unpressurized pathway through the valve into the vessel, inserting a tube through the pathway in the valve and into the vessel, transferring at least one composition into the vessel through the tube, removing the tube from the vessel and from the pathway in the valve, closing the valve to seal the vessel against pressure release, and exposing the vessel and its contents to microwave radiation. The instrument includes a source of microwave radiation, a cavity in microwave communication with the source, an attenuator that forms at least a portion of the cavity, a pressure-resistant microwave-transparent reaction vessel having portions in the cavity and portions in the attenuator, a pressure-resistant valve on the mouth of the vessel, a reciprocating tube for passing through the valve and into the vessel when the valve is open, and means for mechanically inserting and retracting the tube through the valve and into the vessel when the vessel is in the cavity and the attenuator.

    摘要： An apparatus for controllably heating material directly and indirectly by microwave radiation comprises a chamber in which the material to be heated (often to dryness, as for analysis) is placed, a source of microwave radiation for radiating into materials in such chamber for controllably heating such a material, and a support for such material, which support comprises a matrix of microwave radiation-transmissive material and a particulate microwave absorptive material dispersed in such matric material, which microwave absorptive material has a Curie temperature, above which it becomes microwave transmissive, so as thereby to prevent excessive heating of the support and the material thereon which is to be controllably heated, and which matrix material is stable and form-retaining at the Curie temperature of the dispersed material. Preferably the support will be of a silicone rubber or a polyfluoroalkylene polymer matrix, such as polytetrafluoroethylene, and the dispersed material therein will be a ferrite, garnet or mixture thereof. The apparatus may include a turntable for carrying a plurality of supports or it may include an automatic electronic balance, in both of which embodiments of the invention computerized controls and/or readout means may be present. Also within the invention are the described support, and processes for effecting such heating and/or drying, in one of which processes a particulate diluent or dispersant for the sample being treated is employed to prevent overheating thereof.

    摘要： An apparatus for ashing materials which comprises a chamber, a source of microwave radiation for direction onto contents of the chamber, and in the chamber a support, such as a fused quartz pad or crucible, for the material to be ashed, and an ashing means of a stable microwave absorptive material, capable of being heated to high temperature by microwave radiation, such as a flat block of silicon carbide or a plurality of such blocks with openings therein to accommodate the crucible. The ashing means is in contact with the support for the material to be ashed and is capable of heating such support and such material to an ashing temperature. When a fused quartz fiber pad, preferably of the non-woven cloth type, is employed on top of and in contact with the ashing means of microwave absorptive material, as a support for the material to be ashed, it is preferred to cover such material with another such pad, which inhibits loss of the ash due to its being carried out of the chamber, as by an exhaust fan, while yet permitting the release of gases generated during the ashing process. Also disclosed are processes for ashing materials and for analyzing such materials for ash content, which processes may be practiced with the aid of the described apparatus.

    摘要： An instrument and associated method are disclosed for preparing samples for column chromatography. The method includes the steps of applying microwave energy to a sample composition containing at least one solvent to encourage a chemical reaction and generate desired products, thereafter mixing an absorbent media with the sample to absorb the solvent, the media being compatible with liquid chromatography that will separate the expected products, being chemically inert to the expected products, and being added in an amount sufficient to provide a substantially dry mixture of the media and the sample, but less than an amount that overly broadens the resolution of the sample during liquid chromatography, thereafter applying microwave energy to the dry mixture of the media and the sample to thereby encourage the solvent to evaporate under the influence of the microwave energy, and thereafter adding the dry mixture of the media and the remaining sample to a liquid chromatography column and separating the components of the remaining sample for identification and purification purposes.

    摘要： A valve that opens and closes in response to changes in the physical environment of the valve. This valve is particularly suited as a relief valve in a microwave system-based, closed vessel digestion procedure. This valve includes a pressure-deformable, resilient wall member having a fluid vent port, and an obstructing member that cooperates with the wall member to open and close the valve.Also provided is a lidded vessel employing this improved valve, an apparatus that includes a microwave system and this lidded vessel, and methods using this improved valve.
