Katsikis, S., et al., Improved Stability and Spectral Quality in Ex Situ Dissolution DNP Using an Improved Transfer Device. Appl. Magn. Reson., 2015: p. 1-7.
Dissolution dynamic nuclear polarization (DNP) has become one of the predominant implementations for DNP. However, the technical implementation of transferring the sample from the polarizer to the nuclear magnetic resonance (NMR) system remains challenging. There is a need for additional technical optimizations in order to use dissolution DNP for biochemical and chemical applications. Here we show how a newly designed pressure dissolution kit considerably improves spectral quality and stability by enabling highly reliable and fast sample transfer to the NMR system.
