QuEChERS Performance Standards Kit • Designed for use in all QuEChERS methods for pesticides in fruits and vegetables, including the original unbuffered method, AOAC 2007.01, and EN15662. • Kit contains organochlorine, organonitrogen, organophosphorus, and carbamate pesticides commonly used on fruits and vegetables. • Volatile, polar, active, base-sensitive, and nonvolatile compounds are included to allow comprehensive evaluation of QuEChERS extraction and cleanup efficiencies, and optimization of GC and LC instrumental conditions. • Ideal for initial method evaluations and ongoing method performance validations. • Analytes are divided into three ampuls based on compatibility for maximum stability and shelf life.* • Precise formulations improve data quality and operational efficiency, spend more time running samples and less time sourcing and preparing standards. • Quantitatively analyzed to confirm the composition and stability of each mixture. • Produced and tested in accordance with ISO Guide 34 and 17025 accreditation. *When combining compounds with different functionalities, chemical stability can be an issue. The analytes in this kit are separated into three mixes to ensure maximum long-term storage stability. For analysis, a fresh working standard should be prepared by combining the three kit mixes in a 1:1:1 ratio to prepare a 100 μg/mL working standard solution. Once blended, Restek does not recommend storing working standards or subsequent dilutions for future use. Contains 1 mL each of these mixtures. 31153: QuEChERS Performance Standard A 31154: QuEChERS Performance Standard B 31155: QuEChERS Performance Standard C Compounds: Cat.# 31153: QuEChERS Performance Standard A (16 components) Acephate (30560-19-1) Azinphos methyl (86-50-0) Chlorpyrifos (2921-88-2) Coumaphos (56-72-4) Diazinon (333-41-5) Dichlofluanid (1085-98-9) Dichlorvos (DDVP) (62-73-7) Dimethoate (60-51-5) Fenthion (55-38-9) Malathion (121-75-5) Methamidophos (10265-92-6) Mevinphos (7786-34-7) Omethoate (1113-02-6) Phosalone (2310-17-0) Pirimiphos methyl (29232-93-7) Propargite (2312-35-8) Cat.# 31154: QuEChERS Performance Standard B (7 components) gamma-BHC (Lindane) (58-89-9) Chlorothalonil (1897-45-6) 4,4′-DDT (50-29-3) Dicofol (Kelthane) (115-32-2) Endosulfan sulfate (1031-07-8) Endrin (72-20-8) 2-Phenylphenol (90-43-7) Cat.# 31155: QuEChERS Performance Standard C (17 components) Bifenthrin (82657-04-3) Captan (133-06-2) Carbaryl (sevin) (63-25-2) Cyprodinil (121552-61-2) Deltamethrin (52918-63-5) Fenhexamid (126833-17-8) Fenpropathrin (39515-41-8) Folpet (133-07-3) Imazalil (35554-44-0) Iprodione (36734-19-7) Metalaxyl (57837-19-1) Methiocarb (2032-65-7) Myclobutanil (88671-89-0) cis-Permethrin (61949-76-6 ) trans-Permethrin (61949-77-7) Thiabendazole (148-79-8) Vinclozolin (50471-44-8)
