AFS12002Atomic fluorescence spectrophotometer

• Introduction

AFS-12002The upgraded fully automatic intermittent pump injection dual channel atomic fluorescence spectrometer is used for trace element analysis. The dual channels can simultaneously determine two elements and automatically adjust the energy ratio of the dual cathode lamps to improve the stability of the measured elements while significantly reducing memory effects. Fully automatic control, convenient, fast, and accurate.

AFS120 02 Atomic Fluorescence SpectrophotometerPerformance characteristics

Measurement method

Dual channel, single element testing, dual element simultaneous testing optional, dual element simultaneous measurement, improves instrument analysis speed.

◆ Light source system

Bundle pulse power supply method, specially designed high-intensity coded hollow cathode lamp; Automatically identify single and dual cathode lamps, and automatically adjust the energy ratio of dual cathode lamps.

Atomizer

Adopting a double-layer shielded quartz atomizer and an argon hydrogen flame low-temperature automatic ignition device, the imported ignition furnace wire has a long service life and low cost, which greatly reduces the memory effect while improving the stability of the measured element.

◆ Light metering system

Adopting a high signal-to-noise ratio photoelectric detection system and a non dispersive fully enclosed light path system with short focal length lens focusing.

◆ Gas liquid separator

Chemical gas-phase gas-liquid separation device, where reactants are fully mixed and in contact, automatically removes a large number of bubbles generated by complex organic components in the body sample online; Secondary gas-liquid separator: equipped with a device for removing water vapor, effectively eliminating water vapor.

◆ Harmful element capture trap device for recovering residual contaminated elements

We use a harmful element capture trap device in atomic fluorescence analysis to recover residual pollutants in the environment (such as arsenic, lead, etc.), especially for the recovery of mercury vapor. It not only avoids secondary pollution in the laboratory but also further protects the safety of instrument operators.
