Chlothianidin

Overview

Chlothianidin is one of neonicotinoid insecticides. It is used for multiple farm products because of its wide insecticidal activity range.  This kit allows an easy, rapid (within 2 hours), sensitive, quantitative, multiple sample analysis of chlothanidin that remains in farm products or in the environment.  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 acetone, hexane or acetic 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 chlothianidin.

          Application examples 

The figures show the comparison between standard curves with 10% methanol and reaction curves drawn with methanol extract of chlothianidin–added farm products (diluted to 10% methanol equivalent).  The overlapping curves; demonstrate the suitability of this kit for analyzing trace Chlothianidin without any interference from the original produce.
