Simple, powerful and multi-configurable reducing vaporization CVAAS mercury analyzer by PC operated.
Ultra-High sensitivity and Excellent Precision
The RA-5A is innovational reducing-vaporization mercury analyzer that is equipped with the world’s highest level of performance in the body that is the smallest in its class. Compared to our previous model RA-3A, the installation space is reduced to half or less (about A4 size).
It requires only 5mL sample and is environmentally-friendly through the direct purge design that reduces reagent consumption and waste production drastically.
The high sensitivity and high accuracy are only available by the equipment dedicated to mercury measurement and further enhanced by the newly designed detector. The sensitivity of the equipment is sufficient to determine even a small amount of mercury below the lower limit specified in the Waterworks Act.
