Short summary
We present the maximum sensitivity of a TOF-CIMS using the collision limit and iodide adducts. We also present an ion adduct declustering scanning procedure which determines the effective binding energies of the detected ion adducts and therefore their approximate sensitivity. The combination of declustering scanning and the collision limit provides an approximate calibration for many compounds in the mass spectrum which would otherwise be impossible to obtain by traditional methods.
