Offering simultaneous analysis for high sample throughput in routine process control operations, the 3560 OES is a polychromator-based system utilising a one meter Paschen-Runge spectrometer. Accurate, high speed determination of elemental concentration for up to 60 elements are the hallmarks of the ARl 3560. Utilising the latest microprocessor technology, a complete multi-elemental analysis can be accomplished in less than a minute -the ideal selection for process control and quality assurance.
