Atomic Fluorescence Spectrometers (AFS) are high-sensitivity instruments designed for the accurate detection of trace and ultra-trace metal and metalloid elements, such as arsenic, mercury, selenium, and lead. Utilizing the principle of atomic fluorescence emission, AFS offers excellent selectivity and extremely low detection limits, making it ideal for applications in environmental monitoring, food safety, pharmaceutical analysis, and toxicology studies. With fast analysis speed, low interference, and cost-effective operation, AFS is an essential tool for laboratories that demand reliable performance in routine and specialized elemental testing.
