Product classification: Syringe Pump Series
Product Overview
The AFS-95 Series Atomic Fluorescence Spectrophotometer, independently developed by Haiguang Company, is designed for high-sensitivity trace and ultra-trace elemental analysis. It is widely used for detecting arsenic (As), mercury (Hg), selenium (Se), antimony (Sb), and other trace elements in environmental monitoring, food safety, quality inspection, geology, mining, and scientific research applications.
