Model 650-40 fluorescence spectrometer with microprocessor control has concave gratings which are driven by stepper motors. With a wavelength range of 200-850 nm, the instrument uses a reference photocell in monochromatic light to achieve a ratio re cording system. A prescan mode function al lows either the excitation or emission monochromator to be scanned at 960 nm/min for automatic location of peak maximum. PerkinElmer 412
Simultaneous I.C.P.A.E.S. Elemental Analyzer Designed for routine use, the JY-48 offers ropid analysis of up to 4 8 elements simultaneously and uses rime-proven techniques to enhance reliabil ity and speed. Will accept two sources. For example: a spark stand plus an Inductively Coupled Plasma source. Use for analysis of ferrous and non-ferrous metals and alloys, oils, industrial effluent, coals, ores and rare earths. Holographic diffraction gratings. Fully computer operated.

AtomComp Spectrometer Separate sampling and excitation anal ysis AtomComp spectrometer system uses t w o excitation sources—electron ically controlled waveform source and inductively coupled argon plasma source. The linear dynamic range is 0 . 0 0 7 - 7 0 % . Jarrell-Ash Div., Fisher Scientific Co. 413
Thermal Analysis Thermogravimetric/Differential Thermal Analyzer TG/STA 780 uses an electronic microbalance to perform simultaneous thermogravimetry and differential thermal analysis of any organic or inorganic substance weighing up to 5 g at t e m peratures up to 1500 ° C . The microbal ance may be adjusted from 5 to 500 mg full-scale deflection and from 50 to 500 μ ν fsd for differential thermal analysis. The analyzer uses a motorized furnace with t w o crucibles—one for the test sample and the other a reference sam ple of inert material with anticipated similar heat capacity.
