The 205 is Stable, Reliable, & Easy to use

    The Buck 205 is our entry model AAS. To make the instrument more affordable we have removed the D2 Background correction, and three lamp turret.

    The 205 has 2 lamp warm up brackets on the back and a single lamp holder inside. The remainder of the instrument is identical to the 210VGP. Many customers with low dissolved solids in their samples use the 205 with great success. 

    The 205 is very popular with educators, since it is designed to be low maintenance and affordable.

    D2 Background correction can be added for an extra $1,000 dollars.

    Standard Features

    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.

      Questions & Answers

      Ask a Question
      • We run a metal finishing shop (plating) and are considering the use of one of these units to monitor iron and Zinc in our post treatment dips solutions. The iron and zinc affect the passivate film negatively reducing the life of their useful corrosion resistance. Additionally we would like to monitor the Nickel, Zinc, and Iron in our trichrome plating bath as well as Zinc and Copper in our nickel plating bath as very few parts / million can have profound affects on the deposits as plated. Do you feel this is a sound machine for managing these process chemistries.

        We have a loyal following with plating shops around the world.  Our Atomic Absorprtion Spectrophotometers can detect PPM levels of Nickel, Iron, Zinc, and copper down to PPM using the flame atomizer, and PPB levels using the Graphite furnace atomizer.

        If you would like to use the 205 I would recommend the 1000 dollar upgrade for D2 background correction.

        Please do not hesitate to contact me if you have any fursther questions.
