Chemical digestion under pressure and temperature for the determination of trace and ultra-trace analysis in downstream processes or synthesis under mild conditions are increasingly carried out in microwave-heated equipment. It was found that under certain pressure and temperature conditions, the yield or efficiency of extraction or digestion processes could be significantly improved.
Fiber optic temperature sensors are the only way to control temperatures in microwave chemistry. The outer jacket of the fiber optic temperature sensor is made out of teflon, at the sensor tip a GaAs-crystal (gallium arsenide) is attached. The probe sensor is completely non-conductive. Optocon’s fiber optic temperature sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use. The fiber optic temperature sensors are also designed to withstand harsh and corrosive environments.
