SPECTJRASPAN IV Lour Cost Computer·Aided Plasma Spectrometers for Trace Element Measurements

SMI is recognized and respected as a leader in atomic analysis and today counts more plasma emission spectrometers in use in laboratories and industries worldwide than any other manufacturer.

Plasma spectrometry is widely accepted because it combines the best features of atomic absorption and atomic emission techniques.

SPECTRASPAN IV — SMI's newest and lowest-cost plasma spectrometer, is a compact, integrated system that performs analyses of elements at trace to major levels including the so-called difficult elements with a minimum of sample preparation. Sequential quantitative analyses of single elements or comprehensive qualitative analysis are available with Spectraspan IV. Conversion between modes of operation can be achieved in seconds.

Among the outstanding features of SPECTRASPAN IV are a unique Echelle grating that provides high dispersion of all wavelengths from 1900 to 8000 A° in a 4 χ 5 in. area and a built-in microprocessor for ease of operation and increased system efficiency.

SPECTRASPAN IV is an up-to-date analytical system that offers substantial capability at a modest price.

For multichannel analysis capability ask for information on Spectraspan III.

A low cost i n teg ra ted system for sequent ia l analysis
