ABSTRACT: There are a lot of steps required in order to analyze pesticides in food. Between prepping the samples and doing both gas and liquid chromatography analyses, the workflows are long. In this series of two workshops, we’ve brought together our latest developments for these critical analyses.

In our first module, we will begin by comparing and contrasting food homogenization techniques and share with you one that we have found to be the most effective for a vast array of food matrices. We’ll also have a discussion to help you determine what sample prep techniques might work best for your samples.

In the second module, we’ll share information on how to speed up the analyses with low-pressure gas chromatography (LPGC) and through incorporating in-line sample preparation (ILSP) in to LC. We’ll begin with comparing LPGC to other common ways to speed up GC-MS analysis and showing how easy it is to install and maintain. We will also show examples of how much faster LPGC is for pesticide analysis. Next, we’ll explain how ILSP uses the power of an LC-MS/MS to streamline and automate sample extract cleanup. In this presentation, learn the science behind ILSP and how to automate your current multiresidue pesticide workflow in an interactive format that will give you the knowledge you need to transform your instrument into an analytical workhorse.

Join us for this pair of interactive workshops to learn how to supercharge your pesticide analysis.
