210VGP Atomic Absorption Spectrophotometer

Standard Features The 210/ 211 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, furnace, or hydride techniques. The three lamp turret has individual controls for alignment and standby mode to keep lamps warm. Direct report generation to a printer or data linking to the optional Buck Analyst software package is easily done using the parallel and RS232C ports. Analytical Performance The Buck 210/ 211 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 Deuterium Background Correction This is the oldest and still most commonly used technique, particularly for flame AAS. In this case, a separate source ( a deuterium lamp) with broad emission is used to measure the background absorption over the entire width of the exit slit of the spectrometer. In the 210VGP & Accusys 211 the deuterium lamp is in-line with the hollow cathode lamp, thus eliminating the need for a double beam system. The benefits of a single beam system are more energy, smaller size, lower cost, and a more sensitivity.
