Simultaneous Determination of Heavy Metal and Mineral Contents in Fruit Juices using Inductively Coupled Plasma Mass Spectrometry

Introduction

In this work, fifteen heavy metals and mineral contents in fruit juices were simultaneously determined by inductively coupled plasma mass spectrometry (ICPMS) after microwave digestion. The analysis results of different types of juices from local market were compared against the new US EPA and WHO regulation limits. The elemental contents were either well below the regulation limits or not detected. The ICP-MS method developed applying helium collision cell technology is fast, sensitive and stable. The method accuracy, repeatability and stability were verified.
