Abstract: Methods and kits for assaying a chemical in a sample are disclosed. The method includes placing an extraction solution and an internal standard in a container. A sample is collected from a first location and placed in the container. The container is transported to a second location where the chemical in the extraction solution is assayed. A kit for transporting the sample from a first location to a second location includes at least one container for holding the sample. The at least one container includes an extraction solution for dissolving a chemical in the solution and an internal standard for calibrating an assay of the chemical. The methods and kits may be used in a system for quantitating an amount of a sprout inhibitor on a tuber, such as a potato.

Abstract: An improved combustion-type fogging apparatus and process for applying herbicides, insecticides and the like, as an aerosol is disclosed herein. The apparatus includes an improved combustion chamber with counter-current flow of combustion and supplemental air along with a stator at the downstream portion of the combustion chamber. The combustion chamber also has a hydrocarbon fuel burner to produce hot gases which along with the combustion air and supplemental air forms a hot gas flow into an aerosol chamber wherein a liquid or molten material is introduced for the purpose of being converted into a stable aerosol or fog for introduction into a storage facility or for other purposes of applying an aerosol of an insecticide, herbicide or other liquid or molten material.
