PNDI (T2), P3DDT, PTQ1, and PII (T2) are MALDI silent in the full measurement range (> m/ z = 150k), except at high laser intensities. In MALDI MS ...
Polymer Analysis by MALDI-Tof MS Waters
WebSince MALDI generates mainly singly-charged ions, m/z values from the mass spectrum are the same as the polymer ion's mass. In general, polymer analysis by MALDI-TOFMS is … WebDec 15, 2016 · Here we extended the method to a synthetic organic material using polymer probes characterized by MALDI-TOF/MS. We first characterized several commercial available polymers, and finally selected polycaprolactonediol 1250 (PCP 1250), a polyester oligomer, as the most convenient for further studies. ina\\u0027s white chocolate bark
