Zusammenfassung:	The present disclosure provides a method of measuring a percent solids content (PSC) of solids by mass in a slurry catalyst composition, where the solids include a catalyst. The method includes obtaining a first time domain (TD) 1H-nuclear magnetic resonance (NMR) spectrum using a time domain (TD)-NMR spectrometer and a test sample of the slurry catalyst composition from which a value of a voltagesignal (a) that represents the slurry catalyst composition is determined. A second TD 1H-NMR spectrum using the TD NMR spectrometer is obtained for a neat sample of the suspension liquid for the solids of the slurry catalyst composition, where a value of a voltage signal (b) from the second TD 1H-NMR spectrum that represents the suspension liquid for the solids of the slurry catalyst compositionis determined. The percent solids content (PSC) of solids in a slurry catalyst composition is then determined with Equation I: PSC = (1- a / b * db / da) * 100% Equation I where x represents mathematical multiplication, a and
