Analytical Information From Primary Data
Analytical Information From Primary Data
We now know how the primary data from your sample is acquired in the
optical unit. But how can the data be used as information in analytical
chemistry? Depending on the chemistry of your application, the luminescence
measured by the fluorescence detector will have different characteristics. You
must decide, using your knowledge of the sample, what mode of detection you
will use.
Fluorescence Detection
When the lamp flashes, the fluorescing compounds in your sample will
luminesce almost simultaneously, see Figure 13 on page 27. The luminescence
is short-lived, therefore the fluorescence detector need only measure over a
short period of time after the lamp has flashed.
