The mixture being analyzed may be composed of organic or inorganic com pounds. Virtually any gas or liquid sample may be handled so long as the individual components in the mixture exert a minimum vapor pressure of 250 microns at room temperature. Trace impurities constituting as little as 0.001 mole per cent of the mixture can be determined. Speed and accuracy of analysis, together with versatility, make the Model 21103 Consolidated Analytical Mass Spectrometer the ideal instrument for the chemical industry. Write today for complete information on this new and improved analytical tool.
