XT-IVType online total cadmium water quality analyzer
Measurement method:TPPS4Spectrophotometric Assays
Basic principle: After mixing the water sample with a regulator, the cadmium in the sample is exposed to alkaline environment and indicator（TPPS4）In the presence of the indicator, a colored complex is formed by reacting with it. The analyzer detects the change in color and converts it into a cadmium value for output. The amount of colored complex generated is equivalent to the amount of cadmium.
IIXT-IVType online total iron water quality analyzer
Measurement method: Phenanthroline spectrophotometric detection
Basic principle: Trivalent iron ions in water samples are reduced to ferrous ions by hydrogen amine hydrochloride. Under the action of buffer solution, ferrous ions react with ortho phenanthroline to form a colored complex. The analyzer detects the color change and converts it into total iron value for output. The amount of colored complex generated is equivalent to the total iron content.
IIIXT-IVType online total nickel water quality online analyzer
Measurement method:Diketoxime spectrophotometric detection
Basic principle: The water sample is oxidized by the oxidant ammonium persulfate, and in an alkaline environment and the presence of an indicator (dimethylglyoxime), it reacts with the indicator to form a colored complex. The analyzer detects this colorConvert the color change into the total nickel value and output it. The amount of colored complex generated is equivalent to the total nickel content.
4XT-IVType online total lead water quality analyzer
Measurement method:TPPS4Spectrophotometric Assays
Basic principle: After mixing the water sample with a regulator, the lead in the sample is exposed to an alkaline environment and an indicator（TPPS4）In the presence of the indicator, a colored complex is formed by reacting with it. The analyzer detects the change in color and converts it into lead value output. The amount of colored complex generated is equivalent to the amount of lead.
5XT-IVType online total arsenic water quality analyzer
Measurement method:Arsenic molybdenum blue spectrophotometric detection
Basic principle: The water sample is first digested by acid at high temperature and then mixed with a regulator. The arsenic in the sample reacts with the indicator in an acidic environment to form a colored complex. The analyzer detects the color change and converts it into the total arsenic value for output. The amount of colored complex generated is equivalent to the total arsenic content
VIXT-IVType online total zinc water quality analyzer
Measurement method: Zinc reagent spectrophotometric detection
Basic principle: After acid digestion, the water sample is mixed with a regulator and then oxidized by an oxidant. In an alkaline environment and the presence of an indicator, it reacts with the indicator to form a colored complex. The analyzer detects the change in color and converts this change into the total zinc value output. The amount of colored complex generated is equivalent to the total amount of zinc.
7XT-IVType online total copper water quality analyzer
Measurement method:Sodium diethyldithiocarbamate spectrophotometric detection
Basic principle: This study uses the sodium diethyldithiocarbamate spectrophotometric method to determine total copper. At high temperatures, various copper compounds in the water sample are oxidized and digested by nitric acid to form divalent copper ions. Under ammonia conditions, copper ions react with sodium diethyldithiocarbamate to form yellow brown complexes. Within a certain concentration range, the absorbance of the system is proportional to the concentration of copper ions, and the total copper content in the water sample can be determined by spectrophotometry.
8XT-IVType online fluoride water quality analyzer
Measurement method:Fluorine reagent spectrophotometric detection
Basic principle: Fluoride ions in water samples react with fluoride reagents and lanthanum nitrate in acetate buffer solution to form colored complexes. The analyzer detects the change in color and converts it into fluoride ion values for output. The amount of colored complex generated is equivalent to the amount of fluoride ions.
9XT-IVType online total manganese water quality analyzer
Measurement method: Potassium periodate method for spectrophotometric detection
Basic principle: The water sample is dissolved at high temperature by an oxidant, and after cooling, it forms a colored complex with a color developing agent. The analyzer detects the change in color and converts this change into the total manganese value for output. The amount of colored complex generated is equivalent to the total manganese content.
10XT-IVType online total chromium water quality analyzer
Measurement method:Diphenylcarbazide spectrophotometric detection
Basic principle: After mixing water sample and strong oxidant for digestion, trivalent chromium is oxidized to hexavalent chromium. Hexavalent chromium reacts with the indicator in an acidic environment to form a colored complex. The analyzer detects the color change and converts it into the total chromium value for output. The amount of colored complex generated is equivalent to the total chromium content.
11XT-IVType Online Hexavalent ChromiumWater quality analyzer
Measurement method:Diphenylcarbazide spectrophotometric detection
Basic principle: After mixing the water sample with a regulator, hexavalent chromium reacts with the indicator in an acidic environment to form a colored complex.
