• Compatible with large-volume sampling accessories for ultra-trace analysis.
• Supports micro-volume sampling accessories for precious or limited samples.

Working Principle
The PF7 Atomic Fluorescence Spectrometer works based on the principle of atomic fluorescence emission.
During analysis, the sample solution is converted into gaseous atoms through chemical generation and atomization processes. The atoms are excited by a specific wavelength light source emitted from the element lamp. When excited atoms return to their ground state, they release fluorescence radiation with characteristic wavelengths.
The instrument detects and measures the fluorescence intensity, which is proportional to the concentration of the target element. Through calibration and data processing, the system calculates the concentration of trace elements in the sample.
The PF7 series improves analytical performance through dual-beam optical compensation, automatic injection control, and efficient moisture removal, ensuring accurate and repeatable measurements.
