a Lower analytical range is equivalent to the LOQ. b Upper analytical range is equivalent to the highest standard (5) of the calibration curve used on daily basis calculated by multiplying this standard by a dilution factor of 25. c Repeatibility of NIST SRM 1849a calculated by using the residues of the duplicates on 9 different days. d Overall average for 3 independent days using NIST SRM 1849a and the laboratory control sample CM01/07. e Reproducibility of NIST SRM 1849a calculated by using the average results of the duplicates on 9 different days. *mg/100g reconstituted final product.
