Integrated electrochemical analysis system
12Prm ∞ abIeElectrometer, experimental device using Faraday shielding box. Bu v curve of near zero for the local amplification, circuit noise is lower than 0.1pA. High current test uses the nominal value of 10n,[link widoczny dla zalogowanych], 10W power resistor to constant potential, from 0mV to 1000mV and a step 1000mV, the test result is positive the current maximum output of 9.89V, the maximum negative current output hook 10.17V. Can meet the technical requirements. 5.1.3 Performance Testing constant potential 5mV signal given by the instrument, external 5K resistor, continuous 15rain, the output signal range of 5.00-5.10mY. Give fixed 3000mV signal, an external resistor 3K, sustained 15rain, the output signal range of 2.9978 ~ 2.9985V. 5.2.1 Qualitative Analysis of the electrochemical performance of 5.2 by stripping voltammetry, the working electrode was glassy carbon electrode, reference electrode was AgIAga (saturated KC1), on the very platinum electrode, supporting electrolyte 0.1mol/LKCI. Take lmLI base solution, 5mL multi-ion tested samples of high purity nitrogen through a hiss D, 1.25V at a concentration 5mln, select one J. 25-2OOO No. 4 of the instruments l30.5V potential window, the scan rate is 50mV / s, the measured dissolution peak shown in Figure 5, according to potentials from negative to positive peaks in the order: zn2,[link widoczny dla zalogowanych], c +, N, Pb2, c. Stripping voltammetry lap 5 when the component quantitative analysis of the unknown ion 5.2.2 Electrochemical c determined the concentration of unknown samples,[link widoczny dla zalogowanych], using stripping voltammetry and the standard addition method, the working electrode was glassy carbon electrode, reference electrode to I0 (saturated KC [), on the very platinum electrode,[link widoczny dla zalogowanych], supporting electrolyte 0.1moVLKa. Take lmL} end solution, 9mL tested samples c, through high-purity chlorine 10rain, enriched in a 1.2V at 5min, select a potential window from 1.2 to A 0.1v, scan rate is 80mV / s, measured stripping peak; plus one standard cmL, stripping peak measured above conditions shown in Figure 6. The calculated concentration of c 1.074 × 10 a g / L. Potenfial ■ 【l1nn Figure 6 Analysis of an unknown sample set C + of the concentration of 6 Conclusion 2000A integrated electrochemical analysis system based on a breakthrough in the design of the past, the limitations of single function devices, changing one or more of the instruments for a fixed experimental or analytical methods of traditional values. In the software and hardware structure design highlights the modular assembly type, easy to expand Heyi upgraded features, the system has the flexibility and agility, adaptability, its function can follow a new method for the development of new experimental techniques continue to improve and perfect.
