Continuous Determination of 11 Microelements in Hops by ICP-MS with Microwave Digestion

Hops were treated by microwave digestion with pre-digestion step.Continuous determination of 11 microelements in hops by inductively coupled plasma mass spectrometry with collision cell technology.The correlation coefficients of various elements were greater than 0.9995,and RSDs were less than 5%with recoveries from 82.0%to 112.0%.
