Features

210VGP Atomic Absorption Spectrophotometer

  • Stable, Reliable, & Easy to use.
  • 3 lamp power supply, (1 internal 2 external)
  • High energy optical design for better As & Se results
  • Compact and lightweight 39"L x 11"W x 12"H; 50 lbs
  • Rugged military grade design stands up to years of abuse.
  • D2 Background correction
  • Free Buck Analyst Software
  • Low cost consumables and maintenance
  • Made in the USA
  • Leasing available for domestic customers
  • Free in-house training for the life of the instrument

The 210VGP 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 Free Buck Analyst* software package is easily done using the parallel and RS-232 serial ports.

The Buck 210VGP 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 gives 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 the 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.
