Product Information
The
205 Advantage
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.
