Resolution Resolution is related to sensitivity, but refers to the
“detail” which can be read. When the instrument
sensitivity level is high, lower concentrations can be
read with ease (high resolution) but higher concentra-
tions can not be read on-scale. When the sensitivity is
low, higher concentrations can be read, but the detail is
not as good at low concentrations (low resolution).
Sens Factor These three terms are synonymous and are used to
Sen % indicate the TD-700 fluorometer's sensitivity on a
Sensitivity Level scale of 1 to 100. Sens Factor is the term used in the
software during calibration, Sens % can be found on the
diagnostic screen, and sensitivity level is the term used
on the printout. The Sensitivity Factor is directly
proportional to the voltage on the photomultiplier tube.
The higher the Sensitivity Factor, the greater the
sensitivity (and typically, the greater the "noise") of the
readings.
Sensitivity The basic operating level of the instrument. It is related
to the detection limits, the dynamic range, and the
resolution. The electronic sensitivity is set during
calibration using the keypad. Sensitivity can also be
adjusted mechanically using different cuvette sizes.
