I do remember them James, but not the details. If they were indeed measuring in real time (must find this out) then I suspect it would have to be electrically...most probably Ion Selective Electrode, which would mean some control for sulphide assuming there is some sulphide content in serum. The ISE will measure silver ions quantitatively if a calibration curve is constructed using the same matrix (base solution), otherwise a detection and relative increase would be recorded.
