Buck Scientific AA
The Buck Scientific 205 AAS uses a unique burner system to get more sample to the flame, which results in more signal and better sensitivity. We use an impact bead nebulizer to get an efficient generation of a fine aerosol of sample solution. The short path spray chamber permits difficult solutions containing organics or high dissolved solids to be aspirated with superb precision and minimal instabilities. To take advantage of this enhanced signal, we designed an optical layout that provides the highest throughput of any commercially available spectrophotometer. Our very simple straight line optical path uses a monochromator with a single reflector mirror. This cuts down on the amount of light loss often associated with models having 10 or more mirrors. Because of this the Buck 205 AAS can detect far-UV elements, such as arsenic and selenium, with ten times greater sensitivity.
