RA-4300A Reduction Gasification Mercury Analyzer

Advanced reduction gasification mercury analyzer with higher accuracy and sensitivity

RA-4300 is a new type of mercury analyzer using reduction gasification method, which has higher accuracy and sensitivity, and is equipped with many necessary functions.

FDFDFD'>The instrument design has been updated, with the detector, reagent distributor, and automatic sampler integrated into a compact box.

FDFDFD'>The instrument will automatically measure the pre treated sample solutions, such as tap water, river water, and industrial wastewater.

FDFDFD'>The sample is pre treated according to the measurement method specified in the standard (such as JIS K0102) to convert all mercury in the sample into divalent mercury ions (Hg2+).

FDFDFD'>When tin chloride solution is added to the pre treated sample, divalent mercury ions (Hg2+) are converted into zero valent metallic mercury, which is then converted into mercury gas through a bubbler.

FDFDFD'>The acid mist and water vapor generated during the mercury bubbling process are removed by electronic cooling devices and other devices, and then the mercury gas enters the absorption tank for mercury detection by atomic absorption spectroscopy.

The instrument has multiple automatic functions and is easy to operate

RA-4300 is the standard model for mercury detection, which ensures that its various functions can improve the reliability of measurement results and is easy to operate.

• FDFDFD'>The stability of automatic detection instruments.

• FDFDFD'>Automatically identify the peak values of mercury and other substances.

• FDFDFD'>Automatically determine the validity of the calibration curve based on preset conditions.

• FDFDFD'>Monitor the flow rate during the measurement process to ensure the reliability of automatic measurement.

• FDFDFD'>The high concentration measurement system and additive recovery detection device ensure the accuracy of measurement results.

FDFDFD'>RA-4300A can use both reusable sampling tubes provided by NIC and commercially available centrifuge tube sampling tubes. RA-4300 can share sampling tubes with other analytical instruments to reduce analysis costs.
