Chlorfenapyr
Overview
Chlorfenapyr is an insecticide and is used for multiple farm products because of its wide insecticidal activity range. This kit allows an easy, rapid (within 2 hours), sensitive, quantitative, multi-sample analysis of chlorfenapyr that remains in farm products. This kit is best applied for inspection at delivery time/prior to processing or primary screening in production sites.
Features
Comparison with instrumental analysis
While instrumental analysis offers high accuracy, it requires complicated and time-consuming pretreatment techniques,and sophisticated instrument operation as well as large quantities of hexane or diethyl ether as organic solvents. The simpler pretreatment required for kit saves significant time. Additionally, only a small quantity of methanol is required as an extraction solvent for analyzing chlorfenapyr.
Application examples
The figures show the comparison between standard curves with 10% methanol and reaction curves drawn with methanol extract of chlorofenapyr-added farm products (diluted to 10% methanol equivalent). The overlapping curves; demonstrate the suitability of this kit for analyzing trace chlorofenapyr without any interference from the original produce.
