Analysis of Multiple Elements in Drinking Water by ICPE-9820

Introduction

The amount of water typically consumed by an adult is said to be about two liters per day, and nearly all of this is tap water or mineral water, generally referred to as "drinking water." Conducting safety inspections are the responsibility of each country according to their respective regulations. Typically, there are many target elements included in the test, such as sodium (Na), calcium (Ca), etc. which are present at the mg/L level or greater, and toxic trace elements such as lead (Pb) and cadmium (Cd), which are normally present at the μg/L level or less. Here, using the Shimadzu ICPE-9820 multi-type ICP atomic emission spectrometer and an ultrasonic nebulizer, we conducted analysis of river water, typically the source of tap water. The ICPE-9820, with its auto-switching of axial/radial viewing which permits total overall measurement from trace to high concentrations, in addition to the newest CCD detector which allows acquisition of all elements over the entire wavelength region, greatly improves analysis throughput for multiple elements and multiple samples. Moreover, as a system designed to reduce running costs, it increases lab productivity.
