Instrument News Analytik Jena introduces new Generation of contrAA® High-Resolution Continuum Source AA Spectrometers (HR-CS AAS) More than a decade after its first commercial introduction with the contrAA® family of instruments, HR-CS AAS has become a well-established and appreciated analysis technology in routine, research and academia. The reasons for this success are the obvious advantages of HR-CS AAS over traditional Line Source AAS: With a Xenon lamp emitting a continuous spectrum at high intensity, any element and wavelength can readily be analyzed whenever the requirement occurs – the contrAA® turned AAS into a true multi-element technique with unmatched flexibility. A high-resolution spectrometer with CCD detector produces a highly resolved absorption spectrum for each sample, providing deeper insight about the sample as well as visual proof of correct signal evaluation. Features like fast sequential and simultaneous multi-element analysis, including semi-quantitative overview screening of unknown samples, and analysis of non-metals have opened up new application fields previously reserved to other, much more expensive technologies. Superior correction algorithms for background and spectral interferences have taken productivity and accuracy of AAS to a new level – all while preserving its simple, robust and low-cost operation. The new contrAA® 800 cumulates the experience gained over the years, feedback and suggestions from the field and our experts’ refreshingly new ideas. With its automatic atomizer switching and two-dimensional atomizer alignment, the contrAA® 800 is a versatile all-rounder that comes in a modern, space-saving design. A redesigned high-performance optical system provides improved stability and lowest noise, resulting in market-leading detection limits and superior accuracy. A new lamp design further reduces consumables costs. Analytik Jena highlights its expertise in high-performance optics with a unique long-term warranty of ten years on the optical components. The newly developed Dynamic Mode makes use of flexible spectral evaluation parameters and enables extension of the dynamic working range up to five orders of magnitude with a single calibration curve. This helps users reduce sample preparation and dilutions to a minimum because the contrAA® is able to adapt itself to any analyte concentration present in your samples – from the ppb- to the percent-range. Complemented by a wide range of accessories including autosamplers and online-dilutors, flow-injection and hydride generation systems the contrAA® 800 is the most versatile AAS available today. SPECTRO Selecting your ICP-OES analyzer’s plasma interface A new white paper reviews the core concepts surrounding the optical interfaces that are available for ICP-OES spectrometers today and discusses the relative strengths and weaknesses of each approach. The paper explains how each technique works and why understanding the plasma-viewing interface should be a major factor in the selection of the best technology for the laboratory’s specific area of research. The paper also introduces a unique new plasma observation technology approach called MultiView, recently introduced by SPECTRO Analytical Instruments in its new SPECTRO ARCOS ICP-OES. MultiView is truly axial and truly radial. The periscope-free design means operators can literally “turn” a radial-view instrument into an axial-view device, or vice-versa — in 90 seconds or less! Users get full axial sensitivity and full radial precision without compromises.
