Abstract
The present invention relates to devices and methods for determining the masses of particles by measuring the time between a first event such as a sample (5) being ionized, (or a beam of electromagnetic radiation being scattered by a particle (15) and electromagnetic radiation scattered by said particle being detected by a detection means,) and a second event in which a beam (21) of electromagnetic radiation is scattered by a particle (15) from said ionized sample and electromagnetic radiation (25) from said beam (21) scattered by said particle (15) is detected by a detection means (11).
