Compositional distribution of polymers
msRepeatFinder combines Kendrick Mass Defect (KMD) and Kendrick Mass Remainder (KMR) plots to visualize compositional distributions of homopolymers with different end groups. The program also calculates parameters related to molecular weight distributions by grouping and color coding each polymer series.
|Total ion intensity||Center of KMD value||Center of NKM value||Number average molecular weight(Mn)||Weight average molecular weight(Mw)||Polydispersity|
Gel permeation chromatography (GPC) combined with high mass-accuracy MALDI-TOFMS
To analyze highly polydisperse polymers, it is effective to combine GPC with high mass-accuracy MALDI-TOFMS. This process displays mass spectra of multiple fractions on Remainder of Kendrick Mass (RKM) plots for visual presentation of compositional distributions.
* The data was acquired in collaboration with the National Institute of Advanced Industrial Science and Technology
MS/MS structural analysis of polymers with different end groups
High energy collision-induced dissociation, which is a fragmentation method specific to MALDI-TOF-TOF, is effective in acquiring various structural information. RKM plots can visualize the difference of end groups.
Analysis of copolymers
In mass spectral data of copolymers, numerous peaks with small mass differences are typically observed.
Fraction Base KMD plots can clearly visualize such peaks compared to conventional KMD plots.
Polymer analysis using field desorption (FD)
In FD, types of polymers to be desorbed and ionized change over time as the current to the emitter is increased.
In KMD plotting, polymers separated over time can be overlaid for visualization.
- Peak lists (up to 10 lists can be overlaid)
- KMD/KMR plots
- Fraction base KMD plots
- Remainder of KM (RKM) plots
- Estimated circles of homopolymer end groups (on KMR plots)
- Color coded groups
- Enable/disable display of polymer series groups
- Calculating average molecular weight/polydispersity of groups
- Export polymer series groups
- Peak list input format: m/z and ion intensity
- The effectiveness of processed results is determined by the mass accuracy of peak lists provided.
