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 83

. The luminescence is 

short-lived, therefore the fluorescence detector need only measure over a 
short period of time after the lamp has flashed.
