Setting Parameters for Semiquantitative Analysis

Semiquantitative analysis is a very powerful feature of ICP-MS, since it provides
reasonable accuracy (±10 - 30%) without the need to run external standards. It scans
through all masses (or selected masses) and reports concentrations for all elements,
based on a stored elemental response database. It is especially useful for screening
unknown samples, or for evaluating new matrices sample types. It is also useful for
determining the concentrations of calibration standards to be prepared for
quantitative analysis.
Because Semiquantitative Analysis is similar to Qualitative Analysis, acquisition
parameters are normally the same. Refer to "Setting Parameters for Qualitative
Analysis", earlier in this chapter.
