Specification of Atomic Absorption Spectrophotometer SHIMADZU AA-7800 - ALAT LABORATORIUM UMUM
The AA-7800 is equipped with a three-dimensional optical system that is automatically set to the optical double-beam mode for flame measurements. In addition, the high-speed digital filter and use of optical components with extremely low optical loss levels achieve data stability and high sensitivity.
Results are shown from measuring 2 ppm of copper for over an hour (average of 11 successive measurements plotted). Over the course of hundreds of measurements, the instrument achieved a relative standard deviation within 1%.
