概要（Overview）

Hitachi - Science & Technology - Z-5700 Polarized Zeeman Graphite Furnace Atomic Absorption Spectrophotometer Optical system and the improved graphite furnace power supply circuit ensure high sensitivities. Using an ordinary hollow cathode lamp, the Z-5000 Series spectrophotometer is capable of analyzing As, Se and Sb in tap water and environmental water, which previously have only been measurable using an EDL high-intensity lamp in a conventional graphite furnace analyses.
