웹2024년 8월 2일 · Base Peak. 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. 웹2014년 1월 7일 · Mass Spectrum. A plot of m/z or mass (abscissae) versus the intensity, frequently normalised to 100% for the most intense ion detected (ordinates). This is produced by scanning the analyser to transmit ions (or release them from a trap) for a predefined range of m/z values over a fixed period of time. Thomson is the unit for mass-to-charge ratio.
