LC Multiresidue Pesticide Kit

  • Accurately detect and quantify pesticides of global food safety concern in a wide range of fruits, vegetables, and other commodities by LC-MS/MS.
  • Full kit contains 204 compounds of interest, covering many LC-determined pesticides listed by government agencies; individual ampuls also sold separately.

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 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.

Oregon Pesticide Standards (6 separate mixes)

  • Meet specific cannabis pesticide residue analysis needs of Oregon – and states with similar pesticide residue regulations/programs.
  • Verified composition and stability.
  • 59 compounds in 6 x 1 mL ampules at 600 µg/mL – resulting in a convenient 100 µg/mL solution when blended immediately before use.
  • Prepared stock product eliminates the need for in-house standards preparation.

    If you formerly ordered these standards as customs, review compound lists before ordering — to improve stability, some formulations were changed slightly.
