Atomic fluorescence speciation analyzer

High end atomic fluorescence analyzer, equipped with PF7 series atomic fluorescence detector The gas source sequential flow injection technology, double beam optical structure, information sample management system and other technologies are adopted.

The morphology separation module adopts special morphology analysis hydride generator, high-efficiency quartz digestion device, pneumatic flow path system and other technologies.

The integrated process control can realize the simultaneous collection of multi-element morphology

analysis, and complete the processing and quantitative calculation of chromatogram, The equipment is divided into sa710 isocratic morphological analyzer and sa720 gradient morphological analyzer, which can meet various needs of different industries.

√ maintenance free

1. The pneumatic flow path system without wearing parts completely gets rid of the maintenance trouble of peristaltic pump

√ commissioning free

1. The detector has a built-in morphological analysis interface, and the analysis mode software can be switched without manual debugging and installation.

√ more stable

1. Detector and speciation analysis coexist in two hydride reaction systems, and the special reaction system is more in line with the working characteristics of speciation analysis;

2. The vapor-liquid separator is used for refrigeration, water removal and mixing, and the sensitivity is 30% higher than that of the prior art;

3. Air source flow path system, constant pressure and constant flow, stable liquid inlet, and baseline long-term noise less than 4MV;

4. The quartz plate digestion tank has a large light receiving area of the flow path, and the utilization rate of ultraviolet ray is increased by 2 times.

√ more environmentally friendly

1. The double row waste outlet design enables the waste liquid to flow out from different pipelines, realizing the separation and storage of organic and inorganic waste liquid, which is more environmentally friendly.
