Let me add my two-cents to this discussion. The best place for the
log amp is in software. With the advent of relatively cheap 14-16 bit
ADCs all data could be collected as high resolution "raw" or linear
data. Any transforms such as log or fluorescence compensation (or
cube-root for that matter) could then be performed mathematically,
which avoids the problems being examined in the current discussion.
The Coulter XL is one instrument that is starting to move in this
direction.
