Sentences with phrase «ion mobility»
Ion mobility refers to the ability of ions (charged particles) to move and migrate through a substance or medium. It describes how easily and quickly ions can travel in a given environment. Think of it like the ease with which cars can move through different types of roads - some roads might be wider and smoother, allowing cars to move faster, while others might be narrower and bumpier, slowing them down. Similarly, ion mobility measures how freely ions can move in a substance, determining their speed and efficiency of transport. Full definition
In addition, the considerable variation in the interface tension followed by a steep increase in ion mobility also contribute to instability.

To identify and structurally characterize biomolecules from complex samples, we perform rapid (µs - ms) two - dimensional gas - phase separations using ion mobility - mass spectrometry (IM - MS) techniques.
Hill has been an innovator in the field of ion mobility for nearly 40 years.
