คำว่า should be spiked to
the matrix ในประโหยกข้างล่างนี้แปลว่าอะไรครฟบผม: For qualitative multi residue methods targeting very large numbers of analytes, it may not be practicable to include all analytes from the scope in each batch of analyses. To verify overall method performance for each batch, at least 10 representative (indicator) analytes(from the validated scope) that cover all critical points of the method should be spiked tothe matrix. In a rolling programme, the performance for all analytes from the validated scope
should be verified as indicated in Table 3.
