An interesting and simple approach to effective multiple‐solvent suppression is proposed using the basic principles of the excitation sculpting methodology. Flat baseline and ultra‐clean NMR spectra are usually obtained under standard conditions using a modified double pulsed field gradient echo scheme in samples con‐taining mixtures of non‐deuterated solvents. The simple performance of such an approach, the high tolerance to experimental mis‐settings, the impressive level of solvent suppression and the easy incorporation of the proposed scheme in multi‐dimensional NMR experiments make this method suitable for possible applications in liquid chromatography NMR. © 1998 John Wiley & Sons, Ltd.
