Comparison of MALDI-ToF-MS spectra (CHCA matrix) of LA products synthesized from variable initial reaction volumes of A 100 µL, B 20 µL, and C 5 µL at a constant 500 mM reactant concentration. Labeled peaks are sodiated (M+Na⁺). The estimated center of mass (m/z) and length (mers) of LA products measured for each spectrum are denoted by thin red dashed lines. Peaklists of these spectra with evidence of polyLA formation are presented in Supplementary Tables S20–S22. Similar results were observed in MALDI-ToF-MS spectra using DCTB as the matrix, which are presented in Supplementary Fig. S6 along with their peak lists in Supplementary Tables S23–S25
