Operating Instructions
Fluorescence Detectors FLD-3100 and FLD-3400RS
FLD-3100
Two monochromators with concave holographic gratings and
hyperbolic mirrors for highest efficiency in light transmission
Xenon flash lamp (15W);
Three different flash frequencies (HighPower, Standard, LongLife) can
be selected.
Reference diode behind flow cell for compensation of lamp intensity
