QuEChERS Performance Standards Kit

More Details
  • Designed for use in all QuEChERS methods for pesticides in fruits and vegetables, including the original unbuffered method, AOAC 2007.01, and EN 15662.
  • 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.

    *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.
