DRAFT AOAC SMPR 2018.XXX; Version 6, July 10, 2018 1 2 Method Name: 3

Identification and Quantitation of Selected Pesticide Residues in Dried

4 5

Cannabis Materials

Intended Use : 6 7 1. Purpose: AOAC SMPRs describe the minimum recommended performance characteristics to be 8 used during the evaluation of a method. The evaluation may be an on-site verification, a single- 9 laboratory validation, or a multi-site collaborative study. SMPRs are written and adopted by AOAC 10 Stakeholder Panels composed of representatives from the industry, regulatory organizations, 11 contract laboratories, test kit manufacturers, and academic institutions. AOAC SMPRs are used by 12 AOAC Expert Review Panels in their evaluation of validation study data for method being considered 13 for Performance Tested Methods or AOAC Official Methods of Analysis , and can be used as 14 acceptance criteria for verification at user laboratories. Consensus-based Reference method.

2. Applicability :

Method, or a suite of methods, to identify and quantify selected pesticide residues (Table 1) in dried

cannabis plant materials.

3. Analytical Technique :

Any analytical technique(s) that measures the analytes of interest and meets the following method performance requirements is/are acceptable. More than one analytical technique may be needed.

4. Definitions :

Dried Plant Material

Dried whole or milled flower plant material from Cannabis sp. and its hybrids.

Limit of Quantitation (LOQ)

The minimum concentration or mass of analyte in a given matrix that can be reported as a

quantitative result. A minimum 3 to 1 signal to noise ratio (S/N).

PPM

mg of analyte per kg of Dried Plant Material (as received)

Quantitative method

Method of analysis where response is the amount of the analyte measured either directly (enumeration in a mass or a volume), or indirectly (color, absorbance, impedance, etc.) in a certain

amount of sample.

Repeatability

Variation arising when all efforts are made to keep conditions constant by using the same instrument and operator and repeating during a short time period. Expressed as the repeatability

standard deviation (SD r

); or % repeatability relative standard deviation (%RSD r ).

Reproducibility

The standard deviation or relative standard deviation calculated from among-laboratory data.

Expressed as the reproducibility standard deviation (SD R

); or % reproducibility relative standard

deviation (% RSD R ).
