General description

Eprinomectin is a second generation macrocyclic lactone, used as a topical endectocide which is active both against endoparasites and ectoparasites for all cattle, including lactating dairy cows.

Application

Eprinomectin has been used as a standard for the determination of pesticide residues in soil samples by the on-line solid-phase extraction-ultra high performance liquid chromatography-tandem mass spectrometry. It may also be used to examine the presence of any veterinary drug residues in the bulk milk tank.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
