The primary reason for this is the reduction the fluorescence that is afforded by the use of a NIR (1064 nm) laser that does not cause electronic transitions. The secondary reason is the ease of sample handling. These attributes, combined with the excellent frequency precision of an interferometer and the relatively narrow bands produced from the Raman effect, make it a potentially superior tool for agricultural applications. However, to realize its superiority proper sampling and data handling must be employed. The use of mulitvariant (chemometrics) rather than univariant techniques for information extraction can also enhance the analytical results. Examples of the use NIR-FT/Raman with chemometric approaches for classification and component prediction of cereal foods will lbe discussed. |
