[RASMB] Abs optics design question

[Brandon L Doyle]

Tom Laue can probably answer this best (he has a publication talking about 
just such an idea).

It is possible, but XLi and XLa are based on mid-80s electronics, and at 
the time A/D processors were just not fast enough.  So Beckman built the 
whole flash lamp, angle delay/trigger system that is in instruments now. 
Without any competition in AUCs, low overall % of their business AUCs 
represent, and no demand from customers Beckman did not feel a business 
need to significantly upgrade the instrument at all.  It is certainly 
feasible today, and is large part of the instrument Tom is developing.

[RASMB] Abs optics design question






Hello all,

This is an idle question about the design of the XL/A (or I)
absorbance optics. Why are the cells scanned one at once?
Would it not be possible to scan them all "simultaneously"
by gating the output from the photomultiplier into a
suitable number of different channels?
