Did you know?
WebCollision cross-sections (σ c) quantify the probability of a collision taking place between two or more particles.For two bodies in collision this represents the effective area of a particle as seen by another passing particle. This is unique to any pair of particles; for example, the interaction between two charged particles will be stronger than that for two … WebDec 28, 2024 · In the context of human and veterinary drugs identification, ion mobility spectrometry (IMS) in combination with mass spectrometry (MS) may provide a relevant complementary piece of information to mass-to-charge ratio (m/z), the so-called collision-cross-section (CCS). Up to now, however, the applic …
