Component | LOD1) (μg/100 g) | LOQ2) (μg/100 g) | Reference value3) (μg/100 g) | Analysis value4) (μg/100 g) | Recovery (%) | RSD5) (%) |
Vitamin D2 | 0.21 | 0.68 | 1.25±0.13 | 1.20±0.24 | 104.17 | 10.23 |
Vitamin D3 | 0.13 | 0.44 | 12.29±0.95 | 12.50±0.70 | 98.32 | 7.76 |
LOD, limit of detection.
LOQ, limit of quantitation.
Referenace value indicates the vitamin D2 and D3 contents of SRM 3235 and BCR-122 provided by NIST and IRMM as the certificate value.
The values are mean±SD of 3 replications.
RSD, relative standard deviation.
