웹2005년 5월 16일 · The TIC shows the sum of the signals from all masses in any given spectrum, plotted versus time. Selected ion current or extracted ion chromatogram (EIC or XIC) shows the signal from a single mass selected by the user, whether or not that mass is the most intense at any given time. The BPC will often look similar to the TIC, but less noisy. 웹再请问johnson, 这个电流，base_current10不是电机的额定电流了？是板子采样时adc最大转换电流，谢谢，还有，就是那基本频率，我看了一下程序，应该是表示电机的额定频率啊，但是为什么ti缺省的是120,我在实验中将它改成了运转时没什么明显的不同，倒底下哪个对啊？

웹既然问题是“质谱是怎样做到定量的？. ”，我们不妨把质谱信号的产生按时间顺序粗略分为三个步骤，即离子的产生，传输与检测。. 产生离子时，不同样品分子的电离通常是相互独立的。. 因此样品量越多，其产生的离子也就越多。. 目前常用的各种离子化 ... 웹2024년 11월 15일 · Basepeak图主要反映样品的色谱分离度、肽段信号强度（可以结合上样体积判断样品酶解情况）、样品中蛋白质的构成复杂程度等。如果从色谱图上看到在不同时间洗脱的峰较多，而且相对丰度较高，则说明样品中的肽段种类较多，复杂程度较高。 the balkan trilogy by olivia manninghttp://www.bioon.com.cn/news/showarticle.asp?newsid=69865 the balkan line movie

"웹Base peaks The main features are the molecular ions as the base peak and the M-t-1 ions arising from another species. For 2-aminothiazole the m/e 73 ion (M-HCN) is shifted to m/e 75 in the spectrum of the dideuteroamino derivative and, therefore, largely arises via rupture of 2-3 and 4-5 bonds (Scheme 18). This fragmentation process could involve the kind of … " - Basepeak图是什么
