View source for 4:1. AAAAAA A6 Is An Impurity From Peptide Synthesis

<br>Supporting Figure S1. ESI mass spectrum of A7 (a) with out Cr(III) and (b) with Cr(III) at a 1:10 molar ratio of A7:Cr. 4:1. AAAAAA (A6) is an impurity from peptide synthesis. Supporting Determine S2. Relative depth of ions formed as a operate of drying gas temperature in °C for (a) A7 and (b) A3KA3. The capillary exit and skimmer potentials have been fastened at -95 V and  [https://unsplash.com/@dinghyoffer75 unsplash.com] -25 V, respectively. Precursor ions are indicated by purple font with a purple arrow with a large diamond head. All product ions are proven in black font with black arrows. Supporting Determine S4. Relative depth of ions formed as a operate of capillary entrance potential in V for (a) A7 and (b) A3KA3. The capillary exit and skimmer potentials had been fixed at -95 V and -25 V, respectively. Supporting Figure S5. ESI mass spectra of the solvent system (ACN:H2O at 50:50 v:v) with erucimide contaminant in colorless secure-lock microcentrifuge tubes after (a) no rinse, (b) 2 rinses, [https://www.dailymotion.com/video/x7vg4us Safe Locker from Cardboard] and (c) four rinses with IPA solvent. Note the decrease in depth of overall background as contaminants change into much less intense. A7. This spectrum could not be obtained with out addition of Cr(III) to the solution undergoing ESI. Undissociated precursor ion is labeled in purple with a big purple diamond arrow head. The spectra have no growth of the depth axis; all peaks are shown to scale. Undissociated precursor ion is labeled in purple with a big purple diamond arrow head. The spectrum has no growth of the depth axis; all peaks are proven to scale. The spectra haven't any expansion of the depth axis; all peaks are proven to scale. A7. This spectrum could not be obtained with out addition of Cr(III) to the answer undergoing ESI.
