Embodiment Construction

[0018] In one aspect, the invention provides an apparatus (eg, apparatus) for performing automated microwave-assisted reactions.

[0019] Therefore, as in figure 1 As shown in, in one embodiment, the present invention provides a microwave apparatus 10 comprising: (i) a microwave radiation source, in figure 1 (ii) cavity 12 ; and (iii) waveguide 13 , in microwave communication with source 11 and cavity 12 .

[0020] The microwave radiation source 11 may be a magnetron. That is, other types of microwave radiation sources are within the scope of the present invention. For example, the source of microwave radiation can be a klystron, a solid state device, or a switching power supply. In this regard, the use of switching power supplies is described in commonly assigned US Patent No. 6,084,226, entitled "Use of Continuously Variable Power in Microwave Assisted Chemistry."

[0021] The microwave device 10 typically includes a waveguide 13 connecting a microwave source 11 to a cav...

Abstract

An instrument (10) for performing microwave-assisted reactions and an associated method are disclosed. The instrument typically includes ( i ) a microwave-radiation source (11), ( ii ) a cavity (12), ( iii ) a waveguide (13) in microwave communication with the microwave-radiation source and the cavity, ( iv ) at least one reaction-vessel sensor (15) for determining the number and / or type of reaction vessels positioned within the cavity, ( v ) an interface (20), and ( vi ) a computer controller (21). The computer controller is typically in communication with the interface, the microwave-radiation source, and the reaction-vessel sensor. The computer controller is typically capable of determining the output of the microwave-radiation source in response to the number and / or type of reaction vessels positioned within the cavity.

Description

technical field [0001] The present invention relates to apparatus and methods for performing automated microwave-assisted chemical and physical reactions. Background technique [0002] "Microwave-assisted chemistry" refers to the use of electromagnetic radiation within microwave frequencies to initiate, accelerate or otherwise control chemical reactions. As used herein, the term "microwave" refers to electromagnetic radiation having a wavelength between about 1 millimeter (mm) and 1 meter (m). In contrast, infrared radiation is generally considered to have a wavelength of about 750 nanometers (nm) to 1 millimeter, visible radiation has a wavelength of about 400 nanometers to about 750 nanometers, and ultraviolet radiation has a wavelength of between about 1 nanometer and 400 nanometers. Of course, the above-mentioned various boundaries are illustrative rather than restrictive. [0003] Since microwave-assisted chemistry was commercially available, microwave-assisted chemis...
