A Matrix Spike and Spike Duplicate (MS/MSD) are representative but randomly chosen client samples that have known concentrations of analytes of interest added to the samples prior to sample preparation and analysis. The MS/MSD is not useful to a client whose sample was not chosen and thus, is not reported to that client unless specifically requested.We're not around right now. Spike recovery (%R) must be within the limits of 75-125%. Products and Services / Standards & Publications / Standards Products Control charts are maintained that are indicative of typical MS/MSD recoveries of ‘real’ samples rather than laboratory controlled samples.The importance of the MS/MSD is specific in nature.

Criteria 1. They are processed along with the same un-spiked sample. In chemical analysis, matrix refers to the components of a sample other than the analyte of interest. h5�ș�q�"��pkօm�
