概要（Overview）

The RA-4300 is a new-type of reducing-vaporization mercury analyzer that has higher sensitivity, higher accuracy, and equipped with many required functions. The design is renewed, and a detector, a reagent dispenser and an automatic sample changer are integrated into a single, compact unit. The solution of samples decomposed through wet-pretreatment, such as tap water, river water, and industrial wastewater are automatically measured.
