Abstract / Summary

In this application note a simple and effective extraction/protein precipitation procedure was applied to the analysis of infant formula.

A simple one-step pass-thru cleanup protocol using Oasis PRiME HLB Cartridges was employed to remove greater than 90% of fats and phospholipids from the initial extracts
The sample preparation methodology produced an extract that was free of particulates and required no subsequent filtration prior to LC-MS analysis
High and consistent recoveries were observed for a wide range of veterinary drugs using the simple one-step pass-through clean-up protocol with Oasis PRiME HLB Cartridges
