Atomic Fluorescence Speciation Analyzer SA-20A

detailed description： The SA-20 series atomic fluorescence morphology analyzer mainly consists of three parts, namely the atomic fluorescence detector, SAP-20 pre-processing device, and data processing workstation. The SAP-20 pretreatment unit includes a high-pressure liquid phase pump, post column pipeline connection, and gas-liquid separation device, mainly for sample separation and pretreatment. The atomic fluorescence detector unit detects the generated gaseous hydrides. The data processing workstation unit controls, collects, and processes instruments.

Online digestion device:This greatly shortens the pipeline, avoids the broadening of the peak shape behind the column, and improves the analytical performance of the instrument.

Gas liquid separation device (patent):(ZL 2005 2 0001620.3 Utility Model Patent Certificate)Reduced the water vapor content entering the atomic fluorescence detector, improved the analysis sensitivity, achieved a water removal effect comparable to Nafion tubes, reduced noise, and lowered the detection limit.

Excitation system:Using a specially designed hollow cathode lamp as the light source, electrical modulation, and bundled pulse power supply method, the service life of the elemental lamp is extended, and sensitivity and signal-to-noise ratio are improved.

Hydrogen Generator:Morphological analysis pre-processing device.
