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.

SPECTRASPAN IV plasma spectrometry at atomic
absorption prices Spectraspan IV computer-aided plasma-emission spectrometers offer far more capabilities than atomic absorption units, yet are competitively priced. Think about it. For about the cost of an atomic absorption unit, you can have a simple totally-integrated system that performs all common atomic absorption analyses plus analysis of: • Boron and phosphorus • E l e m e n t s which form refractory compounds • C o m p l e x s o l u t i o n s having dissolved-solids c o n t e n t s a s high a s 2 0 per cent • High acid concentrations • Trace t o major e l e m e n t concentrations • Difficult e l e m e n t s including s o m e non-metals All Spectraspan IV systems are compact bench-top units designed for sequential quantitative analysis of most elements automatically. Rapid comprehensive qualitative analysis is also available. Conversion from one mode of operation to the other can be accomplished in seconds. These low-cost systems feature unique Echelle Grating Spectrometers that provide high dispersion of all wavelengths from 190 to 800nm, and powerful dedicated INTEL microprocessors that improve operating efficiency by providing overall control, calibration, monitoring, and reporting with minimum operator attention. In addition, Spectraspan IV systems consume little power, and operate on safe, inert argon which eliminates the need for lamps and explosive gases. If you want to increase your capabilities to meet today's analytical requirements without increasing costs, invest in Spectraspan IV. Call SMI now for details. SMI is an acknowledged leader, and the company that has more plasmaemission spectrometers in use by satisfied customers throughout the world than any other manufacturer.
