211 Accusys Atomic Absorption Spectrophotometer

We make AA Easy!

Our goal here at Buck Scientific is to make instruments that are easy to use, and maintain for many years, at minimal expense.  We take a hands on approach to customer service by answering our own phones.  You can talk to the engineer who assembled your instrument, for quick and friendly support.

The Accusys 211 is the next evolution of the highly successful Buck 210VGP, incorporating all of the features of the 210VGP along with an automatic gas box for easy nitrous oxide switch-over, push-button ignition, and automatic flame shutdown in case of flame outage.

• Stable, Reliable, & Easy to use.
• Automatic gas box for N2O changeover
• Automatic gas shutoff if Flame is extinguished
• Push button ignition
• 3 lamp power supply, (1 internal 2 external)
• High energy optical design for better As & Se results
• Compact size and light weight
• 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

Standard Features

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

*BuckAnalyst Software is free to download. Links are at the bottom of the page

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.

Features

• Unique non-flame ignitor provides the safest instrument start-up
• Simple 3 button operation for fully automatic gas controls, ignition and gas switchover (Air to Nitrous Oxide)
• Automatic optimization of analytical parameters when method files are loaded from the 211 built-in Methods Library
• Fully integrated safety interlocks for gas pressure sensors, burner head type, UV flame sensor, drain line trap and ignitor continuity insure safe operation of the 211 AAS
• Upgradeable to the model 220GF back-mounted graphite furnace for ppb/ ppt trace level analyses
• Available autosampler, hydride generator and cold vapor attachments
• Internal microprocessor and software can identify samples, perform statistical analysis and graphically display calibration curves and transient peaks (Hydride generation & Graphite furnace)
