CCS search

Match a measured Collision Cross Section against PubChemLite's predictions within a tolerance window, for a chosen ionization mode or a specific adduct. Optionally narrow further by adding a measured m/z with its own Da or ppm tolerance — a compound matches only when the same adduct fits both the CCS and m/z windows.
