The vertical axis denotes the relative abundance of ions. The most intensive peak in a spectrum is called the "Base Peak", whose intensity is taken as 100 percent. This ion exists most abundantly in the ion source and represents the most stable ion, which is useful for identifying the compound.

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. 웹00:00 00:16. 质谱分析中的TIC XIC BPC的概念与区别: BPC（基峰图）是将每个时间点质谱图中最强的离子的强度连续描绘得到的图谱，TIC（总离子流图）是将每个时间点质谱图中所有离子的强度加和后连续描绘得到的图谱，XIC（提取离子流图）是将每个时间点质谱图中 ... 웹2016년 10월 30일 · 质谱离子的多少用丰度表示（abundance）表示，即具有某质荷比离子的数量。由于某个具体离子的“数量”无法测定，故一般用相对丰度表示其强度，即最强的峰叫基峰（basepeak），其他离子的丰度用相对于基峰的百分数表示。 how many carbs in hominy
