Embodiment 1
[0023] Embodiment 1 vitamin detector quality control product composition
[0024] Ferrocene: 0.1μmol / L—1000μmol / L;
[0025] Potassium hexafluorophosphate: 0.1μmol / L-0.0001μmol / L or tetrabutylamine hexafluorophosphate 0.1μmol / L-0.0001μmol / L or sodium hexafluorophosphate;
Embodiment 2
[0027] Embodiment 2 Imprecision measurement
[0028] The vitamin detector quality control product prepared by the vitamin detector quality control product composition of Example 1 was continuously detected 10 times by the vitamin detector quality control product, high school and low three concentration levels, and the average value, standard deviation and variation were calculated respectively. Coefficient, where (the concentration range of the quality control product at the high concentration level is 80-105 μmol / L, the concentration range of the quality control product at the medium concentration level is: 40-75 μmol / L, and the concentration range of the quality control product at the low concentration level is: 1-105 μmol / L. 35μmol / L). Day-to-day imprecision determination: the quality control products of three concentrations were measured once a day for 20 consecutive days, and the mean value, standard deviation and coefficient of variation were calculated.

Embodiment 3
[0048] Embodiment 3 stability test
[0049] The quality control products were measured once every working day, and the measurement was carried out continuously for 6 months, and the average value and standard deviation of each month were calculated respectively. The results are shown in Table 4.
[0050] Table 4 Stability Test
[0051]
[0052] To sum up, the different indicators detected all meet the requirements of quality control products, therefore, the scheme of the present invention is completely feasible.
