Analysis of Drinking Water by U.S. EPA Method 200.8 Using ICPMS-2040 with Collision Cell

User Benefits

- ICPMS-2040 can achieve accurate analysis and high stability, as well as lower Ar gas consumption and running costs with mini-torch. - Trace elements in drinking water can be analyzed without H₂ gas. - 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-2040. Most elements were measured in collision mode to eliminate interferences. 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.
