Atomic Fluorescence SpectroPhotoMeter

Atomic fluorescence spectrophotometers convert samples into ground-state atoms via an atomizer, excite them with a light source of a specific wavelength to produce fluorescence, and detect the fluorescence intensity to achieve quantitative analysis of elements. They are used for detecting trace metals such as arsenic and mercury, and find applications in environmental monitoring and food safety.
Selection
Select the corresponding light source based on the range of elements to be detected, considering the hydride generation function for compatibility with volatile element detection. Focus on detection limits and linear ranges to meet sample concentration requirements, and choose an atomization system with strong anti-interference capabilities. Evaluate instrument stability using baseline drift indicators, and assess maintenance costs based on the lifespan of core components.
