Main features:
 
1. Various testing methods include linear sweep polarography, stripping voltammetry, cyclic voltammetry and derivative polarography of each method;
2. The conventional polarography and the first and second derivative polarography of the self-adaptive and self-compensating instrument can automatically adapt to various scanning rates and measuring ranges with the best parameters, and automatically compensate the previous current and capacitive current to realize automatic and precise measurement;
3. Automatic measurement and intelligent analysis instrument can perform real-time background deduction, digital filtering, intelligent peak seeking, tangent fitting, peak calibration, and automatically measure peak current and peak potential of polarographic curves obtained in the test process;
4. Automatic data processing can process data statistically according to three commonly used quantitative methods (standard comparison method, standard curve method and standard addition method), calculate concentration content, standard deviation, coefficient of variation and linear correlation coefficient, and display calibration curve and regression equation without manual calculation and drawing;
5. The silly operation instrument can store the user's measurement results, actual measurement methods, all parameters, polarographic curves and numbers on the internal chip for memory, and can be called and inverted at any time to realize silly operation;
6. Use Excel and drawing software to edit the data stored in U disk: polarographic graphics, determination results, experimental parameters, calibration curves, regression equations, etc.;
7. The monitoring software of the anti-virus quick start instrument is solidified on the chip, which will not be destroyed by computer viruses and start quickly;
8. The instrument with high precision and wide measuring range has wide application range and can be used for quantitative and qualitative analysis of constant, trace and trace substances.
