Empower控制质谱使用小贴士（四）| 培训讲座进行时

每周两分钟，见证您成为Empower/质谱小达人！

在前几期中，我们更新了3篇单四极质谱使用小贴士：(I)采集和处理SIR(2D)和MS all Scan(3D)数据(II)结合紫外谱图查看相关质谱信息(III)查看信噪比并对谱图进行平滑。

本期，我们来看下如何理解含噪TIC图的成分检测算法（CODA）。

第1步：

先到Review页面中去查看一个3D MS通道的TIC图。

第2步：

在MS 3D Channel页中设置处理方法, 勾选“enable 3D MS Channel Processing”。然后勾选 “enable CODA” 并采用默认设置。CODA 是一种旨在减少随机噪音和高背景的算法，以简化LC/MS数据的理解。

第3步：

可以将Review界面堆叠图中原始TIC（上图）与使用了CODA的TIC图（下图）进行比较，可以看到色谱的显著改善。

第4步：

或者，您可以在方法集中为TIC图创建一个衍生通道，创建第二个衍生通道然后在此页面勾选“enable CODA”。

第5步：

为整张色谱图创建一个非常简单的禁止积分的处理方法，并对两个衍生通道使用该处理方法。

第6步：

应用这个方法集可以得到与第3步相同的结果。

无论哪种方式，只要使用了CODA的TIC图，小峰的峰形就能得到改善，并且显示出在原始TIC图中看不到的小峰。使用方法集的优点是可以将进样带入到Review中，并打开应用方法集。通过这个方法，只需点击几下，就可以获得改善过的TIC图，还能用于进一步查询峰。就是这么简单！
