1. Performance Features

    It is basically consistent with the national standard method, but has been greatly improved in terms of urine digestion. The formula has been modified so that the substances in the urine can be fully digested, and the online cold digestion is achieved. The entire inspection process is closed, which reduces the damages to the inspection personnel and the environmental pollution into the inspection (test) room.


2.Technical Parameters

Correlation coefficient: R between 0.9990-1

·Linear range: In the range of (10-1200) μg/L, linear correlation coefficient r≥0.990; in the range of (10-100) μg/L, the absolute deviation  ≤ 15 μg/L; in the range of (100-1200) μg/L, the relative deviation ≤ ±10%

·Sensitivity: Minimum response value ≤ 0.8 ug/L of iodine content

·Repeatability: Coefficient of variation (CV) ≤ 6% through 10 repeated tests with the control material (148 µg/L)

·Batch-to-batch variation: Coefficient of variation (CV) ≤ 5% through 10 repeated tests with the control material (148 µg/L) on reagents from different batches of products

·Accuracy: Measured value within the allowable range in determining national iodine standard substance

.Stability: Under the storage condition at 2℃-30℃, the validity  period of urine iodine test kit is 10 months. One kit kept within one month after the expiration date is taken, and its appearance, linear range, minimum test value, repeatability, and accuracy should meet the above requirements.
