ARE YOU USIN6 THE BEST DETECTOR FOR YOUR APPLICATION? Whether you are doing AA, Fluorescence, Absorption Spectroscopy, or Emission Spectroscopy, the detector you are now using may not be optimum. Chances are it is the one that "came with" the instrument, and hence it is the best compromise for the average user. But you may not be the average user. Even more important, recent developments in cathodes have improved S/N, especially in the red. The new R777 has the highest QE, noncrystallin, cathode ever produced by Hamamatsu. The R818 has a lower QE, but it extends further into the red. The use of a CsTe cathode may reduce the effects of remote stray light in a number of short UV instruments. One more point—HTV makes a full line of pin for pin compatible end window as well as side window photomultiplier tubes. Photosensitive devices are HTV's business, not a side-line. You may select either side-on or head-on Hamamatsu PMT's to significantly improve the performance of your instruments.
Explore vapor synthesis with our new Metal Atom Reactor. Our new Metal Atom Reactor* has been especially designed to synthesize compounds by combining vaporized metal atoms with organic chemicals or other reactants. This "vapor synthesis" is used to create radically new compounds, and has generated high interest in the areas of organometallics, metal films, catalysts, solvated metals and potential energy reactions. The Metal Atom Reactor is self-contained and complete including a 3 liter reaction vessel, heat vaporization source, vacuum system, and LN 2 dewars. (As shown $4950.)
