The GR Mo molybdenum water quality online automatic monitoring instrument consists of a sampling system, a metering system, a digestion system, a detection system, and a programmable control system. Collect water samples through an automatic sampling system, and after passing through a high-precision photoelectric sensing measurement system. The sample is melted and leached with alkali, and Mo6+is reduced to Mo5+by ascorbic acid in sulfuric acid medium, thereby reacting with thiocyanate to form a stable orange red complex. Tungsten is masked with citric acid, antimony and bismuth are masked with tartaric acid, and tin is masked with oxalic acid. Other common elements do not interfere. Measure the content of molybdenum using absorbance spectrophotometry at specific wavelengths (differential absorbance spectrophotometry for high concentrations).
Can achieve the functions of standard sample verification and spiked recovery;
Capable of remote transmission control, bidirectional communication, and other functions;
Total amount of liquid for a single sample<>
Equipped with automatic protection and cleaning functions for power and water outages;
Equipped with measurement over limit alarm function, supporting remote setting of over limit values;
Adopting high-resolution color touch screen, easy to operate and rich in information;
Integrated digestion/colorimetric module patented technology, complete digestion, compact structure, high efficiency;
High precision infrared visible photoelectric non-contact measurement system, with high measurement accuracy and high operational reliability;
By conducting two colorimetric measurements on the same sample within one analysis cycle, the sample concentration can be calculated, effectively compensating for the interference caused by sample chromaticity and turbidity;
Through independently designed sampling pipelines, sampling, quantification, liquid discharge, and each reagent have independent pipelines to avoid measurement errors caused by contamination.
