Description

General description

Permethrin belongs to the pyrethroid class of insecticides.

Application

Permethrin may be used as an analytical reference standard for the determination of permethrin in:

• Virgin olive oil samples by liquid-liquid extraction (LLE) or low-temperature precipitation followed by Sep-Pak alumina-N column clean-up and analysis using gas chromatography equipped with electron capture detector (GC-ECD).
• Whole blood samples by electron ionization GC coupled to mass spectrometry (MS) operating in selected ion monitoring (SIM) mode.
• Tomato sample extracts by high performance liquid chromatography (HPLC) with post-column photoderivatization and acetonitrile chemiluminescence based detection.
• Water samples by ultrasound-assisted emulsification-extraction (UAEE) and GC-negative ion chemical ionization (NCI) MS.
• Apple juice samples by matrix solid-phase dispersion (MSPD) and GC-MS.
