Problems solved by technology
[0003] Each traditional heavy metal online analysis instrument only includes one set of the above-mentioned liquid system, and the types of elements that can be detected are limited. Users cannot expand the detection capability of an instrument according to their needs. If more elements need to be detected, they can only purchase more. The method of multiple instruments, the cost is higher

Embodiment Construction
[0028] The heavy metal on-line analysis instrument will be further described below in conjunction with the accompanying drawings and examples.
[0029] Such as figure 1 The heavy metal on-line analysis instrument shown includes a supporting frame 10, three detection modules 20, 30, 40 fixed on the frame 10, a control module 50 fixed on the frame 10, and a water sample pretreatment module (in the figure not shown) and automatic sample retention module (not shown).
[0030] The control module 50, as the central module of the heavy metal online analysis instrument, controls the operation of the detection modules 20, 30, 40, the water sample pretreatment module and the automatic sample retention module. The detection modules 20, 30, 40 operate independently to detect the heavy metal content of the water sample to be tested and transmit the data to the control module 50. The detection modules 20, 30, 40 detect the content of different heavy metals and operate independently without...

The invention discloses a heavy metal online analyzer, which comprises a control module, a water sample pretreatment module controlled by the control module, at least two independent detection modules controlled by the control module and an automatic sample reservation module controlled by the control module; and each detection module independently runs, detects the heavy metal content of a watersample to be detected and transmits data to the control module. The heavy metal online analyzer comprises the at least two detection modules which are independently controlled by the control module respectively, can be separately operated to complete measurement, can be simultaneously operated and have no interference to each other, so the heavy metal online analyzer has low cost and can detect multiple elements.
Description
【Technical field】 [0001] The invention relates to on-line analysis of heavy metals in water bodies, in particular to an on-line analyzer for heavy metals. 【Background technique】 [0002] Traditional on-line heavy metal analysis instruments mainly use two detection methods: optical detection and anodic stripping voltammetry. The heavy metal on-line analysis instruments using these two methods need to add a certain amount of chemical reagents to the sample through a set of automatically controlled liquid system, and then perform spectrophotometry or anodic stripping voltammetry on the sample at the detection position. Quantitative determination. [0003] Each traditional heavy metal online analysis instrument only includes one set of the above-mentioned liquid system, and the types of elements that can be detected are limited. Users cannot expand the detection capability of an instrument according to their needs. If more elements need to be detected, they can only purchase mo...
