Claim 32:
33. A non-transitory computer readable medium storing a computer program including instructions which, when executed by a computer, prompt an apparatus for removing at least a single particulate from a substrate to execute a method of removing at least a single particulate from a substrate;
wherein the apparatus for removing at least a single particulate from a substrate comprises:
a plurality of reservoir vessels that are configured to store a plurality of gases, in which each reservoir vessel is configured to store a respective gas, and different gases are matched with different corresponding materials that are selected from a group of two or more materials that include different elements;
an analysis unit designed to determine at least one constituent of a material composition of the at least one single particulate, in which the at least one constituent of the material composition is selected from the group of two or more materials that include different elements and determine, from among the plurality of gases, a gas that matches the determined at least one constituent of the material composition of the at least one single particulate; and
at least one gas injection system designed to provide a gas matched to the determined constituent in an environment of the at least one single particulate;
wherein the matched gas contributes to removing the at least one single particulate from the substrate; and

wherein the method of removing at least a single particulate from a substrate comprises:
determining the at least one constituent of the material composition of the at least one single particulate;
determining, from among the plurality of gases, a gas that matches the determined at least one constituent of the material composition of the at least one single particulate; and
providing the gas matched to the determined constituent of the material composition in the environment of the at least one single particulate.
