MSP-100E微波萃取仪性能测试

介绍了微波萃取仪压力、温度、微波均匀性和萃取精度的测定。结果表明,MSP-100E微波萃取仪可以在溶剂沸点以下或以上达到±1℃的控制精度,压力差可达到±0.01 MPa,不同萃取位置上的温度差可以处在±1.5℃之内,萃取一个样品的精度(n=5)为1.806%(小于2%),好于超声和索氏萃取的精密度。

Testing Property of MSP- 100E Microwave Extraction Apparatus

It is introduced that the testing studies on the microwave extraction apparatus.The accuracy of the pressure,temperature,the extracting result and the uniform radiated by microwave at the different starting point to the MSP-100E microwave extraction apparatus have been determined.The results show that the controlling accuracy can be at ±1 ℃ for the setting temperature whether the experimental temperature is above or below the boiling point of the applied extraction solvent.The controlling accuracy can be at ±0.01 MPa for the setting pressure value.At the same microwave radiation power and time,the determined temperature value at different starting point is at ±1.5 ℃ to the average value of the all tested temperature points.The extraction accuracy(n=5) is 1.806%(<2%).The determined extraction accuracy for the MSP-100E microwave extraction apparatus is better than the ultrasonic or Soxhlet extraction method.
