共聚物的MALDI-TOF MS分析经常导致复杂的光谱。在MALDI研究之前进行色谱分离/分级可能是有利的，因为级分的MALDI质谱经常显示可区分的共聚物系列的良好分辨的峰。为此，应用了不同的色谱模式。利用组合的空气/电喷雾沉积装置将色谱运行转移到MALDI靶。使用新的MassChrom 2D软件，获得了依赖于分数的2D共聚物组成图，提供了有关色谱模式的额外信息，并能够快速修改条件以增加分离。
The MALDI-TOF MS analysis of copolymers very often results in complex spectra. A chromatographic separation/fractionation prior to the MALDI investigation can be advantageous since the MALDI mass spectra of fractions very often reveal well-resolved peaks of distinguishable copolymer series. For this purpose, different modes of chromatography have been applied. Chromatographic runs were transferred to MALDI targets utilizing a combined air/electrospray deposition device. Using the new MassChrom2D software, fraction-dependent 2D copolymer compositions plots were obtained providing additional information on the chromatographic mode, and enabling fast modification of conditions to increase separation.
