SA-20 atomic fluorescence spectrometer:
◇ At present, the trend of analytical chemistry is to identify and quantify the actual chemical form, not just the determination of the total amount of elements. Different forms of the same element have completely different chemical and toxicological properties.
◇ SA-20 morphology analyzer system uses online chromatography separation-atomic fluorescence detection method for morphology analysis, which is fast and simple, with sharp peak shape and complete baseline separation.
◇ SA-20 speciation analyzer can be used for speciation analysis of metal elements capable of forming hydrides, such as arsenic, selenium, mercury, antimony.
◇ Original in-tube digestion device (PCT patent): greatly improved the digestion ability, can detect more and more complex element morphology, and the pipeline is greatly shortened, avoiding the peak shape broadening behind the column, and improving the analysis performance of the instrument;
◇ The integration of the liquid phase pump and the pre-processing device is realized. The liquid phase pump imported from Germany is ultra-quiet and stable infusion. The liquid crystal display controls the parameters and is easy to operate. The tee made of PEEK is resistant to acids, alkalis and organic solvents. Corrosion
◇ Equipped with the company ’s latest newly developed SA-20 atomic fluorescence spectrometry data workstation, which can realize continuous detection, and trigger data acquisition at the same time of sample introduction. It has powerful spectrum processing functions, a user-friendly operation interface, and complete reports. Output mode, the original SA-10 users can easily and quickly implement the upgrade of the SA-20 software, and meet the user's various requirements for data collection, processing, and report output to the greatest extent;
◇ Gas-liquid separation device (patent): greatly reduces the water vapor content entering the atomic fluorescence detector, improves the analysis sensitivity, and the water removal effect is equivalent to that of Nafion tube, which reduces noise and detection volume;
◇ Dedicated liquid chromatography and hydride generation atomic fluorescence spectrometer interface: it can make the hydride generation of various element forms after chromatographic column separation and introduce into the detector;
◇ As, Hg, Se, Sb and other elemental forms can be detected, and As, Se and As, Sb can be measured in two channels.
◇ The sample consumption is small, only 100µL is required;
◇ All types of atomic fluorometer produced by our company can be upgraded to morphological analysis function.
