Cuvette for the Fluorescence Spectroscopy of NMR Tubes

The inventionis a specially designed, novel dual-use cuvette that would allow for thecontents of an NMR tube to undergo fluorescence analysis in aspectrofluorimeter without having to remove the solution from the NMR tube.Often, it is necessary to determine the contents of an NMR solution before orafter an NMR analysis to determine if the solution has undergone any changefrom its original state. Sample contents can undergo reactions or precipitatefrom the solution, rendering different results than intended without the user'sknowledge. However, removing the sample from the tube runs the risk ofcontaminating the sample or exposing it to reactants before the fluorescence analysiscan be performed. In addition, the sample is rendered unusable when removedfrom the tube because of the risk of contamination.
