base peak

Mass spectrometry is an analytical technique used to identify chemical substances by separating gaseous ions based on their mass-to-charge ratios. Instruments called mass spectrometers utilize electric and magnetic fields to deflect moving ions. The process involves an ion source to create charged particles, an analyzer to separate them, and a detector to measure them. This method is crucial in organic chemistry for determining molecular formulas and structures by analyzing fragment ions. The strongest peak in a mass spectrum, known as the base peak, represents the most abundant ion and is assigned an intensity of 100.123
