Quadrupole mass spectrometry is a fundamental technique in the field of mass spectroscopy, originating from the pioneering work of Wolfgang Paul and Helmut Steinwedel in the 1950s. Today, quadrupole MS is renowned for its rapid scanning capabilities, high sensitivity, and ability to provide quantitative and qualitative analyses. It uses electric and magnetic fields within a mass analyzer to manipulate and filter ions. This method separates and identifies ions based on their mass-to-charge ratio (m/z). Thus, it offers precise mass determinations crucial for various scientific and industrial applications. The far-reaching applicability of quadrupole mass spectrometry is elevated by its compatibility with various ionization sources (chemical ionization, electron ionization, electrospray ionization, etc.). This allows for detailed studies of ion transitions and enables targeted analysis. Read more
