Product Model: TL-900
Measurement Principle
The working principle of TL-900 online thallium analyzer in water is to convert all forms of thallium (including different valence states, organic states, complex states, etc.) into the same valence state through acidification digestion, and then extract online several times after hiding other interfering ions, and then add characteristic color developer to measure the total thallium content in surface water and industrial wastewater.
Detection Process
The pre-treated water sample is injected into a special reactor by an injection pump and reacts with oxidizing reagents. All forms of thallium in the water sample are uniformly oxidized to thallium divalent ion, and then excess oxidant is reduced, and then the pH of the solution is adjusted, and the characteristic chromogenic agent is added for extraction and chromogenic reaction. The degree of color change is proportional to the total thallium concentration in the water sample, and the total thallium content in the water sample can be calculated by measuring the degree of color change.
The on-line extraction technology is used to reduce the detection line of the on-line thallium analyzer in water, so that the instrument can be used for real-time continuous monitoring of thallium concentration in various industries.
Measurement Method
Enrichment colorimetric method/voltammetry.
Multiple Options Are Available
Timing measurement enables the instrument to be started every day at any time the user wants to monitor;
Isochronous measurement can automatically start the instrument for measurement every few hours at a fixed time interval every day;
Continuous measurement can realize automatic sample measurement one by one, which can be used for product acceptance and related technical certification;
Manual measurement can realize the user to start the measurement at any time, and can be used for field experiment comparison and equipment installation and debugging.
