Determine the MDL by multiplying the DL by the typical sample extraction volume and the dilution factor, then dividing by the typical sample weight = concentration in mg kg-1. Replace all sample concentrations which are below the MDL with the MDL value – this allows for further statistical analysis of the data. Calculate the mean CRM concentration.
