Accuracy/Recovery: 96 – 110 %
SMPR 90-110% for Vit B3
The recovery was calculated on all SPIFAN samples and on NIST reference material SRM 1849a. The results
obtained ( 96 – 110 % ) show that the method meets de SMPR recovery for niacin.
Precision (RSD
r
): ≤ 5 %
SMPR : ≤ 5 % for Vit B3
The precision was calculated on 3 SPIFAN samples, in triplicate and the method meets de SMPR.
