수은분석기         RA-2

The RA-2A mercury analyzer is designed to analyze aqueous samples. This rapid easy to use reducing vaporization mercury analyzer has ultra-high sensitivity with a resolution of 0.1ng. The RA-2A Hg analyzer uses non-dispersive double beam cold vapor atomic absorption. Results are obtained in 30 seconds when in "peak" mode and usually in 2 minutes (variable one to 15 min) when in integrating mode. The RA-2A Hg analyzer uses a long-life Hg lamp for excellent long term stability. The tiny 8" x 15.75" footprint conserves expensive bench space.
