Close Enough: The Value of Semiquantitative Analysis
May 01, 2011
Most analytical measurements performed by either inductively coupled plasma–optical emission spectrometry (ICP-OES) or ICP–mass spectrometry (MS) require accuracy and precision, which are essential for obtaining correct answers. However, all modern ICP-OES and ICP-MS instruments have the ability to perform semiquantitative analyses. This seems strange since accuracy is important, but semiquantitative analysis does have a role in analytical measurements. This article will explore why semiquantitative analysis is important and will look at various ways it can be performed and implemented.
