Web6 mrt. 2024 · The primary product ion peak was observed at 0.97 cm 2 V −1 s −1 (Fig. 5 ). There was also a minor peak with a smaller K0 value (or longer drift time) than the peak at 0.97 cm 2 V −1 s −1. At sample quantities of 19 ng and higher, a secondary product ion peak was observed at 1.16 cm 2 V −1 s −1, the K0 value reported for cocaine [ 18 ]. Web13 sep. 2024 · The parent ion peak, which is also called the molecular ion peak, is the peak that stems from the loss of an electron from the molecule. This represents the …

WebBase 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. In a mass spectrum, the relative ... WebThis lesson examines mass spectroscopy in more detail when analyzing parent mass peaks. Specifically, we discuss the M+ peak as well as the M+1 and M+2 peaks...
