1、 Product Introduction:

HD-AFS seriesFully automatic atomic fluorescence spectrophotometerIt is a new generation fully automatic atomic fluorescence spectrophotometer. Adopting an injection pump design with high reliability, intelligence, automation, and maintenance free human-machine interaction, it solves the pain points of traditional atomic fluorescence. This instrument has a wide range of applications, including the detection of trace and ultra trace elements in food hygiene, urban water supply and drainage, environmental protection, agriculture, metallurgy, cosmetics, medicine, geology, commercial inspection, and other fields. For example, environmental sample testing, harmful elements testing in cosmetics, food hygiene testing, geological and metallurgical sample testing, urban water supply and drainage testing, marine environment and aquatic products testing, natural drinking mineral water testing, education and scientific research, clinical medical sample testing, Chinese patent medicine testing, agricultural environmental protection and agricultural products testing.
