Perkin Elmer PE AAnalyst 200

The AAnalyst 200 features the first true double-beam Echelle optical system used in an AA. True doublebeam systems compensate for changes that may occur in lamp intensity during an analysis. The system ensures a more stable baseline and improved performance � precision and detection limits � plus simpler operation. Compared to pseudo double-beam systems offered in other systems, which move an optic or the burner head, the AAnalyst 200�s true double- beam system compensates for any drift multiple times per second, rather than only once between each sample. At the heart of the high performance optical system is a unique solid-state detector designed to provide high quantum efficiency in the UV region. When combined with the high light throughput of the Echelle optical system, even �difficult� elements such as As and Ba can be measured with excellent signal-to- noise ratios. Plus, using a solid-state detector means that no expensive PMT tubes will ever have to be replaced, once again lowering the cost of ownership. More information available upon request.
