We make AA Easy!

Since 1970 our goal here at Buck Scientific has been 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.  Call us today with your AA questions 800-562-5566, or email Eric Anderson sales@bucksci.com.

The 235ATS is designed for analysts requiring nitrous oxide to run Al, Si, Ga, Ge Ba, Be, Ti, Va, Zr, Nb, Mo, Hf, Ta, and W. The automated gas box (seen above) allows for push button oxidant change-over from Air to Nitrous oxide for safety.  The 235ATS also features a flame detector which will turn the gases off shall the flame extinguish.

 Features:

  • 10" color touchscreen
  • Automated wavelength selection
  • Automated Slit selection
  • Easy to operate 5 tab GUI (Graphical User Interface)
  • Automatic gas box for easy changeover from Air to N2O

The New 235ATS will continue Buck's long tradition of making dual beam AA spec.s with in-line Deuterium background correction. Our simple optical design gives our systems superior energy, and better results than double beam AA systems. Our unique design also allows our instruments to have a smaller footprint and a lower cost.

Analytical Performance

The Buck 230ATS 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.

 

Buck Scientific 230ATS Atomic Absorption Spectrophotometer Optical Design

Optical Layout

From the time of the initial developments of Atomic Absorption Spectrometry (AAS) 50+ years ago the concept of the single beam optical system was always a fundamental design consideration. It allowed high energy throughput for the best detection limits, smaller and fewer components for the best size, and low manufacturing costs for the best price. Unfortunately, those original single beam AAS instruments made over 50 years were not used routinely due to the inherent deficiencies in the components of the time: poor hollow cathode lamp characteristics, noisy power supplies, drifting detectors & amplifiers, thermal expansion variations in optical components (mirrors, beam splitters, mounts, etc.), and so forth. To compensate for these deficiencies, and to help them stay in business; the AAS manufacturers developed the double beam optical system that became the standard design for AAS instruments over the next 30 years.

 

Typical Atomic Absorption Optical Diagram

 

By using a high light-loss optical component (the beam splitter) to divide the signal beam from the hollow cathode lamp, served to correct for these low performance components; thus halving the available energy to make a sample measurement, compensation between the reference and sample beams was maintained. In later years, the addition of a deuterium continuum lamp for background correction introduced a second beam splitter; thus cutting the hollow cathode lamp energy in half again. This does not even take into account the 6-10 additional Mirrors used to define the optical path for these large, heavy and expensive (albeit very stable) double beam AAS instruments.

The Buck Scientific line of Atomic Absorption Spectrophotometers were designed to utilize the maximum energy of the single beam optical system. This allowed us to build a smaller, less expensive and more sensitive instrument. Background correction was achieved by inserting the deuterium lamp directly after the hollow cathode lamp.

A general rule of thumb for optical engineers is every time a mirror is introduced into a lightpath it deducts 10% of the energy. So in this case, less really is more!

With a 10" touchscreen computer on-board guiding you through your analysis, using an AA Spectrophotometer has never been easier! The All new Graphical User Interface utilizes five tabbed screens for; Analysis, controls, library, calibration, and samples. The 4 front facing USB ports make connecting a mouse and extracting data onto usb flash discs easy! Our Hideaway keyboard makes naming your samples easy and conveniently tucks in when not in use.
