Analytical Instrumentation A Spectrum in AAS? What Do I Need That For?
A justifi ed question: for half a century, AAS users had to put up with abstract numerical values. How they come about and whether they are actually accurate remains a secret. The High-Resolution Continuum Source (HR-CS) AAS used in the contrAA series from Analytik Jena (Germany) provides the AAS user with signifi cantly more information. Thanks to the combination of a xenon lamp covering the entire relevant wavelength range, a high-resolution spectrometer and a CCD-detector, it has become possible to visually represent the absorption spectra of samples.
This spectrum contains valuable information. It shows, for example, whether the measuring process is interference-free. Thanks to the extremely high optical resolution, spectral interference is very rare. In the event of such an exceptional case, however, spectral representation offers entirely new opportunities for background correction and for the correction of direct spectral interference. Users can now detect any interference at a glance and, if required, correct it using simple methods.

30706pr@reply-direct.com New Modular Gas Standards Generator
KIN-TEK’s (USA) new FlexStream Modular Gas Standards Generating System offers total fl exibility for creating precision gas mixtures. The FlexStream System dilutes the emission from permeation or diffusion tubes with an inert gas (typically nitrogen or zero air) to create trace concentration – ppm, ppb, and pptr – gas mixtures. An internal microprocessor is used to set the operating mode and adjust dilution fl ows to achieve desired concentrations.
The FlexStream System expands the capabilities of the microprocessor controlled, stand-alone FlexStream Permeation Tube Unit. A FlexStream System can have one to six modular channels. Modules available include Standard Permeation units, a Gas-Fed permeation unit for high-pressure gases like methane
Exceptional performance in design of process engineering systems and pilot plants for the petrochemical industry:
• Units according to ASTM D 1160, D 2892, D 5236
• Distillation and extraction plants • Micro reactors for thermal cracking • Catalyst reforming
• Phase equilibrium determination apparatuses

or oxygen, a Secondary Dilution unit to expand the concentration range, and a Humidity Generator to humidify mixtures. Mixtures containing up to 48 components are possible. The FlexStream can use all Kin-Tek Trace Source permeation and diffusion tubes.
The FlexStream System can also be controlled remotely from a PC. Using an external PC allows remote control of the FlexStream, uploading methods (recipes) that can run automatically, and evaluating ‘scenarios’ to aid in setting up the unit to create specifi c mixture concentration ranges.

baths with 2 tubes each, offering a solution for each application and sample load. The modifi ed Ubbelohde viscometers offer a 100-fold measuring range which eliminates the need to exchange tubes frequently. Fitted with an autosampler holding 16 positions per tube, and optional sample preheating as well as dual solvent cleaning, the system is extremely versatile and can be used for a multitude of applications. Its intuitive design combined with advanced control software provides ease of use yet allows for customisation based on sample characteristics.
Omnitek will show the instrument at various international shows. Visit them at the Gulf Coast Conference in October 2014, Arab Lab in March 2015 or the Achema in June 2015. Please check Omnitek’s website for information on their booth number and more.
