You need to use some internal standard so that we can tell whether the peaks are really changing or if you just have different levels of signal. Use the CH peak at ~3000 as an internal standard and ratio to that. I think you will see that you really haven't changed much. Was your IR done in ATR mode? What is the penetration depth. 这是编辑给的意见，求助各位大神帮忙解答一下，下图分别是聚硅氧烷树脂涂层未浸泡（a) 无菌海水浸泡（b) 菌液浸泡（c) 的红外光谱图，internal standard 是什么意思啊？ratio 是怎么计算的？一般红外的探测深度是多少呢？这个问了做测试的老师他说也不知道深度是多少这个问题该如何解决呢？  2-ir-2.gif |
