The 205 is shipped ready for use. All operating conditions are pre-loaded in the internal computer, including lamp settings, secondary wavelengths, and alternate methods of analysis for over 60 elements by flame and hydride techniques.

Direct report generation to a printer or data linking to the free Buck Analyst software* package is easily done using the parallel and RS-232 serial ports.

Analytical Performance

The Buck 205 is a high energy, microprocessor controlled single beam atomic absorption spectrophotometer. Solid state electronics and simple optics provide the basis for our superior stability and sensitivity. The Ebert mount monochromator and user-selectable bandwidth give the system maximum flexibility. Our short-path dynamic nebulizer/burner configuration is highly efficient. An inert needle, precisely positioned in a high flow venturi, delivers sample to the corrosion proof impact bead. This results in a tremendously high nebulization effect for all types of sample matrices.
