fluorescence error

in spectrochemical analysis
Some samples are excited to @[email protected] by the incident radiation beam. When added to the transmitted radiation beam this @[email protected] results in an erroneous @[email protected] called the @[email protected] error. It is particularly noticeable if the photodetector is situated close to the sample.
