LC-AF LC-AF 7590 liquid chromatograph - atomic fluorescence spectrometer
At present, the trend of analytical chemistry is to identify and quantify the actual chemical form,not just determining the total content of the elements.Different forms of the same element have completely different chemical and toxicological properties.So LC-AF 7590 liquid chromatograph - atomic fluorescence spectrometer (atomic fluorescence photometer) was born. Modular design, so the atomic fluorescence spectrometer and speciation analyzer can be used independently.
Specifications:1. Analysis of As\Hg\Se\Sb and other elements in the samples
2. Accuracy ＜3％ (speciation of As, Se, Sb), ＜5％ (speciation of Hg)
3. Special designed UV digestion device is used for online digestion of organic matter with no UV leakage to protect the human body from damage.
4. Speciation analysis of the flow path is strictly calculated and designed with small post-column volume and peak broadening.
5. Nonmetallic PEEK pump head and flow path.
6. Gradient elution can be run to shorten the analysis time, improve separation degree and improve peak shapes.
