Our original installation included two PC's. We never analyse results 
while data are being collected. However, we do have experience of this 
practice with our biosensor system. There we used to find that after 
doing a lot of data analysis the PC was likely to crash while the 
biosensor was collecting results. The Biacore engineer put this down to a bug 
in the PC systems software. Not all of the memory used when a window is opened 
is released when that window is closed, with the result that during a 
long session the working memory dwindles to the point at which the 
Biacore control software cannot run properly. If our engineer is 
correct this problem is a feature of the Windows software, so is 
likely to occur with the Beckman system.
