Field and storage chemical test kit
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.
1. A kit for transporting a tuber sample from a crop storage facility to a chemical analysis facility, the kit comprising:
a container configured to hold and transport the tuber sample from the crop storage facility to the chemical analysis facility, wherein the container comprises an extraction solution for dissolving a sprout inhibitor in the tuber sample, the sprout inhibitor having a volatility that is substantially the same as ethylnaphthalene; and
ethylnaphthalene for calibrating a quantitative measurement of the sprout inhibitor.
2. A kit for transporting a tuber sample comprising a sprout inhibitor from a crop storage facility to a chemical analysis facility, the kit comprising:
a logbook for recording information about the tuber sample;
instructions for how to use the kit; and
a container configured to hold and transport the tuber sample, wherein the container comprises:
a sampling means for collecting the tuber sample from a tuber;
an extraction solution comprising ethanol and trimethylpentane, for dissolving the sprout inhibitor comprised within the tuber sample, wherein the sprout inhibitor is a substituted naphthalene or chlorpropham;
an internal standard comprising ethylnaphthalene for calibrating a quantitative measurement of the sprout inhibitor at the chemical analysis facility; and
a label identifying a known amount of the internal standard.
