Restek is your complete supplier for world-class
LC-MS/MS and GC-MS/MS multiresidue pesticide analysis

We carry certified reference materials, analytical columns, sample preparation products, and accessories.


Stop spending your time and money developing LC-MS/MS or GC-MS/MS multiresidue pesticide methods and mixing reference standards when you could be running samples. Restek’s expert formulations chemists and chromatographers have already done the work for you—with guaranteed accuracy and at a lower cost.

Our certified reference materials (CRMs) for multiresidue pesticide analysis eliminate the need to source, purchase, and store individual materials along with the need to prepare your own mixes. Choose separate ampuls for mix-and-match customization or comprehensive kits each containing more than 200 target compounds, including frequently analyzed pesticides, many of which are listed by government agencies. Designed for maximum shelf life, stability, and chromatographic performance and manufactured under our 10-step quality procedure, each standard is shipped with support documentation detailing our rigorous in-house quantitative testing. We even offer an optimized LC-MS/MS method (downloadable XLS file) and GC-MS/MS method (downloadable XLS file), both of which are free and include conditions and transition tables.

Set up, verify, and validate your pesticide-screening methods in less time, with proven confidence, and at a significantly reduced cost by turning to Restek’s ISO-accredited labs for your multiresidue pesticide certified reference materials. For added convenience and unbeatable results, also consider our internal standards, analytical columns, sample preparation products, and chromatography accessories.

Columns

QuEChERS Internal Standard Mix for GC-MS Analysis (6 components)

Ready to use for QuEChERS extractionsno dilutions necessary.

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.
