Matrix effect definition
Matrix effect means any change in the method detection limit or practical quantitation limit for a given analyte as a result of the presence of other constituents - either of natural origin or introduced by humans as a result of a release or spill - that are present in the sample of water or soil-pore gas being analyzed.
Matrix effect means an influence of one or more components from the sample matrix on the measurement of the analyte concentration or mass. Matrix effects may be observed as increased or decreased detec- tor responses, compared with those produced by simple solvent solu- tions of the analyte.
Matrix effect means the difference in analytical response between a standard dissolved in the solvent and a matrix- matched standard either without a correction using an internal standard or with correction using an internal standard;
Examples of Matrix effect in a sentence
Matrix effect is a prevalent issue encountered in mass spectrometry measurements.
Matrix effect was the ratio of ISTD peak areas acquired from brain lysate samples with IS solutions spiked-after extraction and academic IS standard samples.
Matrix effect on these tests is also assessed by spiking/linearity checking.
More Definitions of Matrix effect
Matrix effect means any increase in the Method Detection Limit or Peak Quantitation Limit for a given constituent as a result of the presence of other constituents, either of natural origin or introduced through a release, that are present in the sample of water or soil-pore gas being
