Technical indicators:
(1) Measurement object
a. Direct measurement of liquid samples
b. For solid samples, after conversion to aqueous solution, it can be quickly measured without separation, enrichment and proper dilution.
(2) Detection limit: ≤ 0.03 × 10-9g/ml when defined by three times the standard deviation.
(3) Measurement accuracy
When the uranium concentration is in the range of 0.1 to 2 x 10-9 g/ml, ≤ ± 8%.
When the uranium concentration is in the range of 2 to 20 x 10-9 g/ml, ≤ ± 5%.
(4) Range: 0.03 × 10-9 g / ml ~ 20 × 10-9 g / ml. If you change the sensitivity, you can expand to the order of 10-6 g/ml.
(5) Measurement linearity: correlation coefficient >0.995.
(6) Stability: The sensitivity is adjusted so that the sample with a uranium concentration of 2×10-9 g/ml reads about 950, and the maximum deviation of 7 measurements within 3 hours is ≤±8%.
