Analysis of Drinking Water by U.S. EPA Method 200.8 Using ICPMS-2050 with Collision / Reaction Cell

User Benefits

- ICPMS-2050 can achieve accurate analysis and high stability, as well as lower Ar gas consumption and running costs with a mini-torch. - Se can be measured with higher sensitivity using reaction mode. - Avoids a complex investigation of conditions by using the analytical conditions from preset methods.

Introduction

Method 200.8 , developed by the U.S. Environmental Protection Agency (EPA), is an ICP-MS method for the analysis of trace elements in groundwater, surface water, and drinking water. EPA 200.8 is a method based on analysis with no gas mode. On the other hand, ICP-MS is commonly equipped with collision/reaction cell technology to eliminate interferences such as polyatomic ions. In this Application News, drinking water and a certified reference material were analyzed by ICPMS-2050. Most elements were measured in collision mode to eliminate interference, but reaction mode was used to measure Se for higher sensitivity. Spike recovery and long-term stability were evaluated with reference to EPA 200.8 quality control (QC) requirements. The analytical conditions used in this application can be easily registered from preset methods, enabling measurements to be performed without the need to develop them.
