工作原理：
Phosphax Sigma总磷/正磷酸盐分析仪基于钼蓝法，聚磷酸盐和含磷化合物在高温、高压的酸性条件下水解，生成正磷酸根，过硫酸钠进一步把其他稳定的含磷化合物氧化为正磷酸根。正磷酸根离子在含钼酸盐的强酸溶液中，生成的锑化合物被抗坏血酸还原为蓝色的磷钼酸盐。总磷/正磷酸盐分析仪测量磷钼酸盐的吸光度，从而完成样品中总磷的测定。
含有悬浮物的水样在进入总磷/正磷酸盐分析仪前，需要经过SIGMATAXTM 2 样品预处理系统处理，系统采用全新的真空负压样品采集与传输和先进的超声波粉碎技术，将悬浮物全部粉碎并导入总磷/正磷酸盐分析仪测量，从而准确分析水样中全部的磷。
应用行业：
Phosphax Sigma总磷/正磷酸盐分析仪可提供地表水、生活污水、工业废水总磷的测定与含量的自动分析监测；工业循环水总磷/正磷/有机磷的连续自动监测，控制缓蚀阻垢剂的自动添加。
仪器特点：
● 总磷/正磷酸盐分析仪可自动分析总磷及正磷，并直接显示出含磷缓蚀阻垢剂的浓度。
● 总磷/正磷酸盐分析仪采用符合标准方法（DIN38 405 D11）的钼蓝法测量，检出限低，响应速度快，总磷的测定仅需10分钟左右。
● Phosphax Sigm总磷/正磷酸盐分析仪配备SIGATAX2样品预处理系统，适用于含悬浮物的水样中总磷的测定。
● 具有自动校准功能，准确度高。
● 具有自动清洗功能，维护量小。
● 总磷/正磷酸盐分析仪配置安全防护面板，有效保护操作人员的安全。
● 总磷的测定结果可以图形或数据显示。
