   This is especially important for solid samples where there is a strong matrix influence. [5] In cases with complex or unknown matrices, the standard addition method can be used. [ 3 ] In this technique, the response of the sample is measured and recorded, for example, using an electrode selective for the analyte.

   A particularly useful method involves depositing the matrix solution on the surface of the sample probe in a solvent that will evaporate very rapidly, thus forming a very thin fine layer of matrix. The sample solution is then placed on top of the matrix layer and allowed to evaporate slowly, thus integrating the sample into the top layer of ...
