SEC(GPC)-MALDI TOF MS
Analysis Example of Co-polymer
The following figure is an example showing the analysis and detection of minor homo polymers in a complex synthetic polymer sample. A two component copolymer [poly(methilmethacrylate-b-n-butylmethacrilate) (poly(MMA-b-n-BMA)] was used as a model complex polymer sample. Fifty fractions were prepared on a MALDI sample target by spotting GPC eluted solution every 6 seconds (T = 8 min 20 sec to 13 min 20 sec). Automated MALDI-MS analysis of the fraction collected at T = 11 min 18 sec resulted in the detection of two polymer series which could not be easily detected in the unseparated sample (see figure below). The newly developed GPC-AccuSpot-MALDI system facilitates the detection of PnBMA and PMMA homo polymer components, present as minor components, in complex copolymer samples, allowing Polymer Analysis calculations to be performed.
