◼ Sigla em inglês MSD (Matrix Spike Duplicate)
◼ Outras denominações em Português Duplicata de Matriz “spike”
Significado
A matrix spike duplicate is an additional replicate of the matrix spike sample following the same sample preparation and analytical testing as the original sample. MSDs are used to document the precision and bias of a method for a specific sample matrix. Following MS and MSD recovery results, the Relative Percent Difference (RPD) is reported for each analyte as a means of measuring reproducibility. In addition to RPD, we provide control limits for MS-MSD recovery ranges for each analyte to evaluate performance.
