Whether you are doing AA, Fluorescence, Absorption Spectroscopy, or Emissions 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 the 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.
