WebTime-of-flight mass spectrometry (TOFMS) is a method of mass spectrometry in which an ion's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. tatcha the rice wash 20 mlWebMALDI is a soft ionization technique used in mass spectrometry (MS) that produces rapid and efficient ionization of a wide variety of molecules (see Figure 1).
