Embodiment 1

[0022] Embodiment 1 Vitamin detector quality control product composition

[0023] 2,3,5,6-Tetramethyl-1,4-phenylenediamine: salt solution;

[0024] The concentration of 2,3,5,6-tetramethyl-1,4-phenylenediamine is 1μmol / L-500μmol / L;

[0025] The salt solution is sodium sulfate: 0.1μmol / L~3.5μmol / L or sodium chloride 0.1μmol / L~3.5μmol / L or potassium chloride 0.1μmol / L~3.5μmol / L or potassium chloride (purity ≥97% );

Embodiment 2

[0026] Example 2 Measurement of Imprecision

[0027] The vitamin detector quality control products prepared by the vitamin detector quality control product composition of Example 1 were tested continuously for 10 times with three concentration levels of high, medium and low concentration levels, and the mean, standard deviation and variation were calculated respectively. coefficient, (high concentration: 90-125 μmol / L, medium concentration: 40-85 μmol / L, low concentration: 5-35 μmol / L). Inter-day imprecision determination: The three concentrations of the quality control substances were measured once a day for 20 consecutive days, and the mean, standard deviation and coefficient of variation were calculated. Vitamin detector parameter settings:

[0028] Rest time: 5s

[0029] Enrichment time: 0s

[0030] Enrichment voltage: 0s

[0031] Scanning voltage range: -0.1V-0.7V

[0032] Step voltage: 30mV

[0033] Voltage amplitude: 40mV

[0034] Pulse width: 60mV

[0035] Peri...

Embodiment 3

[0046] Example 3 Stability test

[0047] The quality control material was measured once every working day for 6 consecutive months, and the mean and standard deviation of each month were calculated respectively. The results are shown in Table 4.

[0048] Table 4 Stability test

[0049]

[0050] In conclusion, the different indicators detected all meet the requirements of the quality control product, therefore, the solution of the present invention is completely feasible.

Description

technical field [0001] The invention belongs to the field of quality control of vitamin testing items, and in particular relates to a quality control product composition of a vitamin detector and application thereof. Background technique [0002] The human body has little demand for vitamins, and long-term primary or secondary vitamin deficiency will lead to physiological dysfunction of the human body and induce various diseases; on the contrary, excessive intake will easily lead to overload accumulation and even poisoning. The content of vitamins in the body is an effective indicator of nutritional status, and the intake of vitamins is particularly important for pregnant women, infants and young children. As a means of evaluating rational drug use, improving the safety and effectiveness of vitamin use, and realizing individualization of vitamin therapy, vitamin monitoring is gradually being valued by clinical practice. In routine clinical testing, due to the wide distribut...
