Detailed explanation-2: -In chemical analysis, matrix refers to the components of a sample other than the analyte of interest. The matrix can have a considerable effect on the way the analysis is conducted and the quality of the results are obtained; such effects are called matrix effects.

Detailed explanation-3: -The matrix effect is the effect on an analytical assay caused by all other components of the sample except the specific compound (analyte) to be analyzed.

Detailed explanation-4: -December 2019. What’s a matrix type? A matrix is the specific type of a sample; for instance a type of sample is a water, but this can cover a wide range of matrix types, from Drinking Water through to Untreated Sewage.
