3. Product features

1. The single-chip data processing system and printer printing function are designed in the instrument, and the working curve method and one-point method software commonly used by customers are compiled, which can automatically calculate the linear correlation coefficient, the regression curve equation, and the sample test results. The introduction of the one-point method makes the test pass rate of the mercury standard test sample up to 95%, which improves the performance-price ratio of the instrument.
2. Automatically feed reducing agent and discharge waste liquid, the gas circuit is completely closed, and the excitation area is shielded with inert gas to prevent fluorescence quenching, which improves the sensitivity and stability of the instrument.
