A rapid and wide-range method, based on light addressable potentiometric sensor (LAPS), is introduced into determination of Cd(II), Pb(II), Cu(II) and Hg(II) in fish tissues. A compact LAPS module is prepared by integrating four LAPS chips specifically sensitive to target elements. Its responses in digestions from various settings are investigated to find suitable factors. Analytical properties of this method are evaluated in consequent experiments under optimized conditions. Measurement range for each target element exceeds 0.1 to 1000mgL, and response time is less than 10s. Accuracy, precision and selectivity of the proposed method are also well defined in measurements. It is successively performed to detect the target elements in real fish samples from 4 species, and obtained results are consistent with certified method.
一种基于光寻址电位传感器（LAPS）的快速、宽范围的方法被引入到鱼类组织中 Cd(II)、Pb(II)、Cu(II)和 Hg(II)的测定中。通过整合四个专门对目标元素敏感的 LAPS 芯片，制备了一个紧凑的 LAPS 模块。研究了其在不同环境下消化时的响应情况，以找到合适的因素。在优化条件下，通过后续实验对该方法的分析性能进行了评估。每种目标元素的测量范围超过 0.1 至 1000mgL，响应时间小于 10s。在测量中，该方法的准确性、精密度和选择性也得到了很好的定义。该方法成功地用于检测来自 4 个物种的实际鱼样中的目标元素，得到的结果与认证方法一致。
