EPN is a non-systemic organophosphate insecticide that inhibits the activity of acetylcholinesterase (AChE) and causes hyper excitation. Activated by contact and ingestion, it is used for protection against lepidopteran and other leaf-eating larvae.
As per Regulation (EC) No. 1107/2009, repealing directive 91/414/EEC, EPN is not approved for use in the European Union as a plant protection agent.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
EPN CRM may find the following uses:

  • Development of a method to analyze 142 insecticide residues in weed and agricultural crops samples by dispersive solid-phase extraction (d-SPE) extraction and liquid chromatographic-mass spectrometric determination (LC-MS)
  • Simultaneous analysis of eight pesticide residues in green tea leaves and infusion samples by gas chromatography (GC) micro electron capture detector (μECD), followed by a confirmation using GC/tandem mass spectrometry (GC/MS/MS)
  • Employing thin-layer chromatography/direct analysis in real-time time-of-flight mass spectrometry (TLC/DART-TOFMS) along with isotope dilution technique for the determination of organophosphorus insecticides in dumpling and grapefruit samples
  • Multi-analysis of 131 pesticide residues in different types of tea samples by dispersive solid-phase extraction (d-SPE) and gel permeation chromatography-gas chromatography-tandem mass spectrometry (GPC-GC-MS/MS)
  • Qualitative and quantitative analysis of 412 pesticide residues from different chemical classes in cotton samples using GC-MS/MS and LC-MS/MS
  • Investigate the presence of 160 pesticide residues simultaneously in chamomile, thyme, and marjoram samples by GC-MS/MS
