SPECTRASPAN III versatility in element analysis from trace to major levels The unmatched versatility and performance of Spectraspan III plasma-emission spectrometers ensure high productivity in a wide variety of analytical applications. In the quantitative mode of operation, a built-in microprocessor and programmed cassettes permit either sequential analysis of single elements automatically, or s i m u l t a n e o u s analysis of up to. 2 0 different e l e m e n t s . No special techniques are required to set up the cassettes, and conversion trom one type of analysis to the other can be achieved quickly. And for rapid, comprehensive qualitative analysis of unknown elements even at trace levels, or for troubleshooting, Spectraspan III converts to operation as a highresolution spectrograph in less than one minute. Other unique features of Spectraspan III total-measurement systems include: • The ability to handle s o l u t i o n s with dissolved-solids c o n t e n t s as high a s 2 0 per cent. • Reduced c h e m i c a l and spectral interferences. Improved d e t e c t i o n limits and wider linear dynamic range. Broad application.

Modular construction to permit future expansion.
In addition. Spectraspan III systems are safe and economical to operate because the plasma is sustained in low-cost inert argon which eliminates the need for lamps and explosive gases.
