“…DMS sampling is an application of DBS technology used in non-blood matrices [ 73 , 74 ], in which a dye is added to the collection paper to indicate the location of the dried sample points. When a transparent or nearly transparent analyte, such as cerebrospinal fluid, saliva, tears, or synovial fluid, is dried on the collection paper, it is difficult to not only know the location of the visual spot, but also guarantee accurate removal and extraction of the sample spot for testing.…”

“…This strategy is capable of compensating for both random and systematic errors and for improving the precision and accuracy compared to other quantification methods (e.g., method of addition). Several articles have been published concerning the application of internal standard (IS) for simultaneous multielement analysis by LS-GFAAS 38,51,[140][141][142][143][144][145][146][147][148][149][150][151][152] and HR-CS-GFAAS 78,80,85,153,154 (Table 4). An element is considered an ideal IS when specific requirements are fulfilled such as: The IS does not occur in the matrix at significant concentration levels; it is capable of performing simultaneous measurements with the analyte; it presents physicochemical properties as similar as possible to those of the analyte; and the signals of both the analyte and the IS are found within the dynamic range.…”
