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.
