Example of a technique for evaluation of interferences
caused by complicated sample matrix elements
in ICP–AES determination

Abstract An example of a useful and rapid procedure for
the evaluation of interferences caused by complicated
sample matrices in inductively coupled plasma atomic
emission spectrometry (ICP–AES) is described. Using
simple acid–base standards, all the elements investigated
were determined separately in complicated matrices with
satisfactory results. Multiple linear regression was used to
calculate the linear correction coefficients for each matrix
element analyzed. Good analytical results improved still
further when this correction method was used.
