The development of an NMR probe operating at highpressure is described. It can operate up to 1.5 kbar, with a burstpressure of 2 kbar. The pressure chamber consists of a simple cylinderbuilt from fibre‐glass–epoxy resin composite material. Itsinternal diameter is 6 mm. The main 1 H coil is buried inthe composite material. Simple O‐ring seals are used, mounted on aconical housing. This set‐up allows the mounting of an additional coilat ambient pressure, acting through the composite material, withlittle loss of efficiency compared with a regular NMR probe, thusallowing the acquisition of heteronuclear NMR experiments. Thesensitivity and resolution permit 1D and 2D studies of aqueoussolutions of large biomolecules such as proteins. © John Wiley& Sons, Ltd.
