WebSep 1, 2006 · Both negative and positive ion modes could be used for the analyses of the mixtures of oligonucleotides. MALDI (+) mass spectra showed better resolution than MALDI (−) mass spectra in linear mode at the same laser powers. However, the detection of negatively charged ions provided better sensitivity for the high molecular weight oligomers. WebApr 30, 2024 · A detailed comparison of the signal-to-noise ratios before and after recrystallization clearly indicated the advantages of a recrystallization step: under identical experimental conditions absolute signal intensities were found to be increased by 30–65% in the negative ion-mode, and from 5 to 23% in the positive ion-mode (see ESM, Fig. S7 ). garmin fenix 5 wristband
