MEMORANDUM SUBJECT:

Pittsburgh Spectroscopy Conference, 1962

Varian's introduction of the revolutionary A-60 spectrometer took the 1961 Pittsburgh Conference by storm· Here's a preview of Varian at Pittsburgh for 1962. W Q will show a new variable temperature accessory for the A-60 spectrometer, further extending the versatility of this instru­ ment. The attachment will allow sample temperature to be varied over a range of 0°C to-f200°C. Also featured will be an advanced EPR system, applicable to many chemical disciplines. This system includes a new 9" electromagnet with EPR performance capability equalling that of a 12" magnet; a new transistorized 7 kW power supply; improved switching circuits for ease of operation; and a complete line of research accessories, such as electrolytic cells, superheterodyne detectors, and rapid-flow mixing chambers ο This improved EPR system also includes a double-resonance cavity, providing a new technique for line-width calibration. A n other V a rian contribution to spectroscopy will be a new NMR Spectra Catalog, including 363 spectra. The spectra are pre-calibrated and cross-indexed by chemical shift, functional group, and chemical name We will demonstrate our new G-14 graphic strip chart recorder, which features instantly-selectable multiple ranges down to 1 mV, ideal for gas chromatography0
