Abstract
A microreactor in which a pressure sensor 10 is provided in a reaction channel 6. A controller monitors the pressure and supplies solvent to the reaction channel if it detects a pressure rise indicating that precipitation is occurring.
Claims10
A microreactor comprising a reaction channel;
- means to supply first and second chemical reagents to flow through the reaction channel;
- a pressure sensor to monitor the pressure in the reaction channel;
- a means to supply solvent to the reaction channel;
- and a controller to receive a signal from the sensor and to cause the solvent to be supplied to the reaction channel if the sensor senses a pressure in the reaction channel which indicates that precipitation is occurring.
A microreactor according to any one of the preceding claims, wherein the controller is arranged to indicate the presence of precipitation when the rate of change of the pressure or pressure differential exceeds a threshold value.
A microreactor according to any one of the preceding claims, wherein the solvent is arranged to, be introduced into the flow channel at the flow junction of the first and second reagents.
A method of avoiding precipitation in a microreactor;
- a supply of at least two chemical reagents to flow through the reaction channel, a supply of solvent to the reaction channel, and a sensor to measure the pressure within the reaction channel, the method comprising the steps of monitoring the pressure within the reaction channel, determining when the pressure within the reaction channel rises to an extent which indicates that precipitation is occurring, and supplying solvent into the reaction channel to prevent further precipitation.
