Abstract
The invention is a method and associated instrument for microwave assisted chemistry. The invention includes the steps of directing a continuous flow of fluid through a microwave cavity while applying microwave radiation to the cavity and to the continuous flow of materials therein, monitoring the pressure of the fluid in the cavity; and cooling the fluid in the cavity when the pressure exceeds a predetermined setpoint pressure.
Claims18
A method of microwave assisted chemistry comprising:
- directing a continuous flow of fluid through a single mode microwave cavity while applying microwave radiation to the cavity and to the continuous flow of materials therein;
- directing the fluid from the cavity to a spectroscopic flow cell and spectroscopically evaluating the fluid;
- and
- moderating the conditions in the cavity in response to the spectroscopic evaluation.
An instrument for microwave assisted chemistry comprising:
- a microwave cavity;
- a flow cell in said cavity;
- a spectroscopy cell external to said cavity and in fluid communication with said flow cell;
- a spectrometer with said spectroscopy cell in the optical path of said spectrometer for analyzing the characteristics of fluids flowing from said flow cell and through said spectroscopy cell;
- and
- a system for moderating conditions in the cavity in response to spectroscopic analysis by said spectrometer of fluids flowing from said flow cell and through said spectroscopy cell.
An instrument for microwave assisted chemistry comprising:
- a microwave cavity;
- an attenuator releasably engaged with said cavity and in microwave communication with said cavity;
- a flow cell releasably engaged with said attenuator in a manner that fixes the positions of said attenuator and said flow cell with respect to one another when they are engaged and that correspondingly fixes said flow cell in the same position with respect to said cavity when said attenuator is engaged with said cavity.
