Standard Test Method for Multi-residue Analysis of Pesticides in Dried Cannabis and Hemp Raw Materials Using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) 使用液相色谱-串联质谱法(LC-MS/MS)对干大麻和大麻原料中农药的多残留分析的标准试验方法
发布日期: 2022-07-01
1.1 本试验方法允许测定下列农药的浓度: 表1 并适用于大麻植物的任何干燥原料( 注1 , 注2 )无论其来源的大麻植物类型如何 ( 1. , 2. ) . 2. 为简洁起见,从现在起,“大麻”一词应用于指任何类型的大麻植物,包括可归类为大麻的植物。该程序包括对研磨的均质样品进行二次采样,用乙腈:乙酸(100:1,v:v)进行液-固萃取,用C18 SPE介质进行固相萃取,用0.1%甲酸稀释在水中的3 mM甲酸铵中,并用0.02%甲酸以20:80的比例(v: v) 并通过LC-MS/MS进行分析。该程序涵盖从样品制备到分析物定量的整个过程,范围为0.005 µg/g至0.500 µg/g。 拟除虫菊酯=拟除虫菊酯I和II 尖晶石Ram=尖晶石J和L Spinosad=Spinosyn A和D 注1: 对于本试验方法,来自大麻植物的干燥原料包括一个或多个花序、叶子或茎。 注2: 某些司法管辖区或法规可能要求包含或排除电厂的特定部件进行分析,这些法规将优先于电厂部件的选择。 1.2 单位- 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 表1 列出了通过该测试方法测量的分析物。 1.4 本标准并不旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前建立适当的安全、健康和环境实践,并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ===意义和用途====== 5.1 为了解决健康和安全问题,满足测试和标签要求,并满足监管g 该试验方法有助于提供中所列分析物的定量结果 表1 ,这是大麻监管文件中农药测试要求的一个子集,不限于并包括加拿大、已合法化的许多美国州和欧洲药典 ( 1- 4. ) 本试验方法可适用于其他农药和生长调节剂分析物,这些分析物可添加到以下分析物中: 表1 前提是根据实践进行验证 D8282 分析物可从 表1 而无需额外验证。
1.1 This test method allows for the concentration determination of the pesticides listed in Table 1 and shall apply to any dried raw material from a cannabis plant ( Note 1 , Note 2 ) regardless of the type of cannabis plant from which it was derived ( 1 , 2 ) . 2 For the sake of brevity, the term “cannabis” shall be used from now on to refer to any type of cannabis plant including those which can be classified as hemp. The procedure includes sub-sampling a ground, homogenous sample, liquid-solid extraction with acetonitrile:acetic acid (100:1, v:v), solid phase extraction with C18 SPE media, dilution in 3 mM ammonium formate in water with 0.1% formic acid and 3 mM ammonium formate in methanol with 0.02% formic acid in a 20:80 ratio (v:v) and analysis by LC-MS/MS. This procedure encompasses the entire process from sample preparation to analyte quantitation encompassing a range of 0.005 µg/g to 0.500 µg/g. Pyrethrins = Pyrethrin I and II Spinetoram = Spinetoram J and L Spinosad = Spinosyn A and D Note 1: For this test method, dried raw material from a cannabis plant includes one or more of inflorescence, leaves, or stems. Note 2: Certain jurisdictions or regulations may require specific parts of the plant to be included or excluded for analysis and those regulations will take precedence for the selection of plant parts. 1.2 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 Table 1 lists the analytes measured by this test method. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The analysis and reporting of pesticide content in all forms of cannabis raw material that is grown or processed or both, with the intent of ingestion or consumption, is required to address health and safety concerns, satisfy testing and labeling requirements, and meet the regulatory guidelines of various jurisdictions where cannabis has been legalized for ingestion or consumption for medicinal or recreational purposes, or both. This test method is useful in providing quantitative results for the analytes listed in Table 1 , which is a subset of the pesticide testing requirements found in regulatory documents for cannabis, not limited to and including Canada, many U.S. states where legalization has occurred, and the European Pharmacopeia ( 1- 4 ) . This test method may be appropriate for additional pesticide and growth regulator analytes, which may be added to those of Table 1 provided validation is performed in accordance with Practice D8282 . Analytes may be removed from Table 1 without additional validation.
