§ 4942. Approved Testing Method for Testing Industrial Hemp for THC Content.
(a) Sample Preparation.
(1) The laboratory shall maintain chain of custody upon receiving the samples.
(2) Each composite sample shall be maintained and tested separately for THC content.
(3) All parts of the plant included in the composite sample shall be processed and tested as a single sample. No plant parts shall be removed during the sample preparation and testing.
(4) All parts of the plant included in the composite sample shall be dried until the weight of the composite sample remains constant after drying intervals. Drying temperature must not exceed 90 degrees Celsius. Dried composite samples shall be milled to a homogenous powder-like consistency and combined before analysis.
(b) Suitable analytical instrumentation used to determine THC content in industrial hemp includes the following:
(1) Gas chromatography with flame ionization detector
(2) Gas chromatography coupled with mass spectrometry
(3) Liquid chromatography coupled with mass spectrometry
(4) Liquid chromatography coupled with ultraviolet detector
(c) Analytical instrumentation used must be able to establish a validated limit of quantification (LOQ) of one-tenth of 1 percent or lower for total THC content.
(d) Sample Retention.
(1) If the laboratory test report indicates a percentage content of THC that is equal to or less than three-tenths of 1 percent, the laboratory shall retain the sample for a minimum of 30 days from the testing date.
(2) If the laboratory test report indicates a percentage content of THC that is greater than three-tenths of 1 percent and does not exceed 1 percent, the laboratory shall retain the sample for a minimum of 60 days from the testing date.
(3) If the laboratory test report indicates a percentage content of THC that exceeds 1 percent, the laboratory shall retain the sample for a minimum of 90 days from the testing date.
