求助微谱数据
|
做多糖降解的，产物拿去做600MHz 碳谱，结果出来的图与文献报道的相差太大，以下是碳谱数据，求牛人帮忙搜索一下。降解的产物可能是混合物。以下是多糖的基本单元  以下是之前一次C谱的图（和下面数字显示的差不多），还有一个做了MALDI-TOF质谱的质谱图，有经验的大侠帮忙看一下。   C谱（重水溶解）：60.00,60.42,60.92,62.50,68.25,68.51,68.88,69.13,69.26,69.56,69.73,72.06,74.92,75.03,76.90,79.54,80.47,81.61,82.14,88.27,97.76,97.95,101.85 [ Last edited by cc1000ml on 2013-9-10 at 17:02 ] |
