Guideposts on the Road to Selection
Choosing a detector requires evaluating many operating parameters and desired outcomes. This introduction provides a series of guideposts that will help lead the way to the right one. Any number of medical, industrial and analytical applications requires the detection of light. Chemiluminescence, bioluminescence, fluorescence and atomic absorption are just a few, and all require a detector to convert the light into an electrical signal. There are three basic technologies that accomplish this...
