Currently, in fields including the food field, the study to apply a 3D fluorescence spectrum (fluorescence fingerprint), with a large amount of sample-specific numerical data, for the determination of agricultural product origins and the evaluation of grain powder types and grades is being conducted. 

In general, chemical analysis is used for the analysis of foods and agricultural products. However, the preparation is necessary and it takes a long time to analyze multi-specimens. 
On the other hand, the analysis by a fluorescence spectrometer, which provides a sample-specific fluorescence fingerprint, characteristically allows the direct measurement of a sample without any preparation. 

This time, an example of the analysis by the microplate reader accessory, which allows the efficient 3D fluorescence measurements of multi-specimens at the highest scan speed for the instrument class (60000 nm/min), is introduced here. The microplate is usually used for the multi-specimen analysis of solution samples. However, it was used to analyze solid sample as its structure allows the fluorescence measurement on the sample surface.
