Solenoidal microcoil probe

FIGURE7.14 Instrumental setup for CE-NMR with online NMR detection using a solenoidal microcoil probe. 

Figure 6.45 Microbore LC-NMR layout. A Microbore HPLC system with a 0.5 mm X 150 mm C18 column is interfaced to a solenoidal microcoil probe. The transfer capfllary is connected to the NMR flow cell with a polyamide resin. Reproduced from [85] with permission. Copyright 1999 American Chemical Society.

The size of sample required has been reduced by a number of technical developments including micro inverse probes and micro cells (references in Martin et al. 1998), and has been reduced even further using a newly developed 1.7-mm submicro inverse-detection gradient probe (Martin et al. 1998). The combined use of inverse detection probes with solenoid microcoils has also been developed to reduce sample volumes for NMR (Subramanian and Webb 1998).
