โฆ Synopsis
Previous Fourier transform mass spcctrometry (FT51.S) mcasurcments have commonly utilized frequency swept escitation. This communication describes the first demonstration of random-noise escitation for FTb1.S employing a simple noise acitation source. Characteristics of the source are discussed and a random escitation spectrum is compared with the corresponding frequency sweep excitation spectrum.
