JMS-S3000 SpiralTOF™ series Polymer Mass Spectra Collection
November 2021 edition
This booklet is a collection of polymer mass spectra acquired by using JMS-S3000 SpiralTOF™-plus matrix-assisted laser desorption / ionization time-of-flight mass spectrometers (MALDI-TOFMS).
Please refer the legend on page iii regarding the information attached to each mass spectrum.
Note that none of the mass spectra in this booklet shows a guaranteed performance specification of the mass spectrometer.

PMMA (poly(methyl methacrylate))
| Structure | H[CH2C(CH3)(CO2CH3)]nH; H(C5H8O)nH | Two formulae, one showing structural information and the other showing elemental composition(s) of the repeating unit(s). If the end groups are unknown, the formula is shown as, for example: -(C5H8O)n- |
| Ion Species | [M+Na]+ | Detected ion species |
| Molecular weight Information | Mn 1498; Mw 1559; D 1.041 | Molar mass information calculated from the observed mass spectrum, NOT the values declared by the manufacturer. |
| Matrix | DCTB | Matrix used for the measurement |
| Cationization agent | NaTFA | Cationization agent used for the measurement |
| Mode | SpiralTOF:Positive ion | Mass analyzer mode and polarity of ions detected |
KMD (Kendrick Mass Defect) plots generated by the msRepeatFinder software are shown for the polymers other than homopolymers with only one kind of end groups.
KM (Remainder of Kendrick Mass) plots generated by the msRepeatFinder software and estimated product ion structures are shown for TOF-TOF (tandem MS) product ion mass spectra.
