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.
