Brief introduction With the development of industry. The lead pollution is becoming more and more prominent lead content in blood and some blood lead only to a conventional single inspection department of children, pregnant women and the occupation disease groups has become a check, some 5 trace elements in the equipment, the user only needs to lead the individual instruments, single, single channel DS-3A (special type of lead and cadmium), is this kind of user settings. Features Single electrode system special for measuring trace element analyzer, blood lead, with imports of glassy carbon electrode, stable performance, and has the function of dissolution and anodic dissolution potential, comply with the rules for the inspection of 1996 and the Ministry of health industry standard WS/T21. The user can choose the method, little sample, less reagent consumption, low detecting cost, standard instrument calibration using whole blood, accurate, good repeatability, the instrument performance is stable, high credibility of the findings. Technical parameters 1, the Telegraph: rotating glassy carbon electrode is equipped with imported. 2, trace element analysis method and the function: function of stripping, stripping potential function. 3, the detection limit: O.1 mg / L (to measure lead as an example) 4, the coefficient of variation: RSD = lO% 5, the correlation coefficient is greater than or equal to 0.99: 6, the relative deviation of the calibration curve: less than or equal to 10% (to measure lead as an example) 7, detection methods: potentiometric stripping or anodic dissolution determination of lead
Introduction
With the development of industry. The lead pollution is becoming more and more prominent lead content in blood and some blood lead only to a conventional single inspection department of children, pregnant women and the occupation disease groups has become a check, some 5 trace elements in the equipment, the user only needs to lead the individual instruments, single, single channel DS-3A (special type of lead and cadmium), is this kind of user settings.
