A soft-landing (SL) instrument for depositing ions onto substrates using a laser ablation source is described herein. The instrument of the instant invention is designed with a custom drift tube and a split-ring ion optic for the isolation of selected ions and is capable of operating at atmospheric pressure. The drift tube allows for the separation and thermalization of ions formed after laser ablation through collisions with an inert bath gas that allow the ions to be landed at energies below 1 eV onto substrates. The split-ring ion optic is capable of directing ions toward the detector or a landing substrate for selected components.
