From the initial pioneering development of electrospray ionization esi by fenns group the application of esi mass spectrometry esi ms for studying noncovalent complexes has important utility in biology biochemistry and biomedical research esi ms has begun to be viewed as a useful tool for investigating the general area of molecular recognition proteins and other biomolecules interact to form functional molecular machines they interact through electrostatic . This is because mass spectrometers separate particles by calculating their different mass to charge ratios m z example ionization methods include atmospheric pressure chemical ionization apci electron ionization ei electrospray ionization esi chemical ionization ci inductively coupled plasma icp ionization and matrix assisted laser .
