Chem.2008, 80,783-792 ¹ØÓÚÕâ¸öÆ×ͼ£¬½éÉÜÈçÏ£º A contour plot (Figure 9) deduced from the RPLC/APCI-TOF separation was produced by means of a method described in detail elsewhere. This 2D plot reports the ion intensities of the various oligomers as a function of the number of methylsiloxane and dimethylsiloxane units. Only ions with m/z > 600 Da were taken into account in order to avoid the contribution of low-mass ions coming from in-source decompositions. The estimation of the average polymerization degrees gave for each sort of repeat unit: DPn (DMS) ) 14.9, DPn (MS) ) 5.4. »¹ÓоÍÊÇËÓйØÓÚ2D MS·½ÃæµÄ×ÊÁÏ£¬µç×ÓÎĵµÄÜ·ñ¹²Ïíһϣ¬Ð»Ð»£¡ |
