Product Code: AS2000
application
The Single Flame Atomic Absorption Spectrophotometer (FAAS) AS2000 is a brand new product carefully crafted by Optosky. The original optical path design greatly improves the sensitivity in the ultraviolet region. The outstanding mechanical and optical system, coupled with excellent software, ensure the accuracy of measurement.
The economical single flame atomic absorption spectrophotometer AS2000 can install 4 hollow cathode lamps at the same time, providing 6 slits (automatic switching); the instrument has good stability, wide measurement range, low detection limit, high resolution and high sensitivity; The software adds a method storage function. Users can store the standard curve and call it up at any time, which can save analysis time and adapt to your pursuit of automated and accurate measurement results.
