One exemplary miniaturized detection coil former for NMR spectroscopy includes a macroporous carrier material having a first surface and a second surface situated opposite thereto, as well as a multiplicity of discrete pores formed in the carrier material and having a diameter in the range of 500 nm to 100 .mu.n being arranged in a manner distributed over at least one surface region. The pores extend through the carrier material from the first to the second surface. A radiofrequency microcoil is embedded in the macroporous carrier material. The detection coil former finds particular utility in an NMR overall analysis system for the NMR-spectroscopic analysis of chemical compounds in the liquid phase.
