LAR的QuickCODultra是一款终极的在线COD分析仪,即便是在最复杂的废水应 中, QuickCODultra 也能测出其中的化学需氧量(COD)。

准确分析。 干净, 迅速,精确。

准确分析。 干净, 迅速,精确。与寻常标准方法相比,寻常的方法即 耗时又多含有危险试剂,而QuickCODultra则采用燃烧法,此方法快速 且开始考虑到有机物在水中的的氧化时的需氧量。这种方法不用任何使 用危险和蚀刻的物质,使得整个运营过程能得到安全的保证。

此方法另一个优点是: 该测量结果是能完全氧化且不受氯化物的干扰。


包含颗粒等的原始水样通过拉尔独特的注射系统注入高温燃烧炉。在 超高温方法下,氧气被用来氧化所有的有机组分。

通过特殊的氧气检测器 检测这种需求量,所以仪器能测量到真实的需氧量。即使有是不断变化的样品成分,QuickCODultra也能可靠地确定化学需氧量。

对我们的QuickCODultra 来说,高盐浓度完全不是问题。



COD化学需氧量的测量过程不超过2分钟。这个速度可以保证在每天的测量周期中 每个极短的峰值都能被检测到。


The COD value indicates the amount of oxygen which is needed for the oxidation of all organic substances in water.
