Cuvette for the Fluorescence Spectroscopy of NMR Tubes
- 詳細技術說明
- 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.
- *Abstract
-
This cuvettewould assure that the sample could be analyzed in a spectrofluorimeter in thesame state as it was analyzed in an NMR spectrometer. The cuvette would allowthe tube to be inserted into a spectrofluorimeter in a position so as to bestationary and entirely exposed to the ultraviolet radiation emitted by thespectrofluorimeter. In addition, the cuvette itself is designed to cause nointerference with the ultraviolet radiation, so the data provided will onlyreflect the radiation's effect on the NMR sample. In order to avoid spuriouslight from interfering with spectrophotometric experiments, a special cap wasdesigned which allows only light from the spectrometer source to interact withthe sample. The cuvette is compatible with air- and water-sensitive samples,and biological samples.
