AAS(Atomic Absorption spectrophotometer) Z-2000 series :Hitachi High-Technologies Corporation

Z-2000 Series
Polarized Zeeman Atomic Absorption Spectrophotometer

Easier Operation, More Reliable Analyses and Higher Sensitivity

This is the concept of Z-series polarized Zeeman AAS.Three models are available to meet your specific needs.

High Quality---Excellent Sensitivity using Zeeman Method and Dual Detector.

Compact---Installation Space is Reduced (Z-2300/2700)

Useful Design---Slim design with built-in Graphite Furnace Autosampler

Topic : Application for the Quality Evaluation of Recovered Rare Metals/Rare earth elements
The recycling of "urban mines" has recently attracted attention. The Hitachi polarized Zeeman atomic absorption spectrophotometer (AAS) is expected to play an active role in the field of urban mine recycling for the impurity analysis, etc., of a recovered rare metal.

Features

Excellent sensitivity
New optics and improved graphite furnace power supply circuit enhance sensitivity. Using common hollow cathode lamps, Z-2000 Series spectrophotometer is capable of analyzing As, Se and Sb in tap water and environmental water, which previously have only been measurable by using EDL (high-intensity) lamps in conventional graphite furnace analyses.

		Model Z-2000 TANDEM TYPE ATOMIC ABSORPTION SPECTROPHOTOMETER The polarized Zeeman method featuring low noise and high stability is adopted for both flame and graphite furnace methods. Highly accurate analysis is achievable with no need for moving sample compartment or adjusting optics.
		Model Z-2300 FLAME ATOMIC ABSORPTION SPECTROPHOTOMETER The polarized Zeeman method featuring low noise, high stability and high throughput is adopted for the flame method. Easy operation is supported by Analysis Assist, Real-time QC and Easy Start functions.
		Model Z-2700 GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROPHOTOMETER Highly accurate background correction is possible by Direct Current (DC) polarized Zeeman method. Integrated design with autosampler and dustproof cover.
