Hi Kara, A log amp works the same way in a flow cytometer as it does in any other piece of equipment. It serves to amplify the voltage in a logarithmic manner as opposed to a linear manner. I suppose that if you really want to know the details of a log amp it must be described in Horowitz and Hill (the art of electronics) and is implemented in its simplest form as an op-amp with a diode in the feedback loop. There is a web page out there at http://nucleus.immunol.washington.edu/Research_facilities/Apps/logscale.html that does a nice visual job describing a log vs. linear amp. -Dave ************************************************************* David Novo Dept. of Physiology CHS C8-134 (310) 206-8160 ************************************************************* On Wed, 23 Feb 2000, Kara E.
