Accurate pesticide analysis ensures food and environmental samples meet regulatory standards and reduces the risk of exposure to harmful contaminants. While traditional QuEChERS extraction is effective for pesticide analysis, the followed clean-up of the QuEChERS raw extract by dispersive solid phase extraction (dSPE) poses challenges in terms of time, labor and cost efficiency.
The latest advancements in micro-solid phase extraction (μSPE) offer streamlined, automated sample cleanup, overcoming the limitations of manual dispersive solid-phase extraction (d-SPE).

µSPE lets researchers
achieve their
goals faster.
Pesticide analysis plays a key role in ensuring food and environmental safety. By ensuring
compliance with regulatory standards, it helps minimize the risk of exposure to potentially
harmful contaminants.
QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction is commonly
used to clean samples during pesticide analysis. Initial extraction uses solvents, such
as acetonitrile, and partitioning salts to separate the sample from unwanted matrix
compounds. Following this, additional extraction often relies on manual dispersive solidphase extraction (d-SPE) to further purify samples. However, this conventional approach
creates challenges in terms of time, labor and cost efficiency and requires large quantities
of solvent during analysis. In contrast, the latest technological advances in micro-solid
phase extraction (μSPE) overcome many of these limitations and offer the ability
to automate sample clean-up.
This infographic explores how μSPE provides a streamlined solution for pesticide analysis.

Manual dispersive workflows use a series of labor-intensive processes to extract samples of
interest. Each additional step in this process prolongs the analytical workflow, creating more
opportunities for inaccuracies and increased processing costs.
By automating repetitive tasks and minimizing manual intervention, μSPE accelerates
throughput without compromising accuracy. μSPE streamlines the sample preparation
process, significantly reducing labour time and solvent usage, allowing scientists to spend
more time on valuable data analysis.
Understanding the limitations of traditional workflows allows laboratories to make informed
decisions about which clean-up approach suits their needs. The adoption of cutting-edge
techniques, such as μSPE, can unlock efficient workflows, accurate analysis and provides
cost-effective approaches to pesticide clean-up and analysis.1-3
μSPE offers the opportunity to improve a range of workflows through cost savings, efficiency
and advanced analytical capabilities.
By unlocking efficient and streamlined workflows, μSPE empowers laboratories to achieve
operational excellence and meet regulatory requirements with confidence. μSPE cartridges
pair with the PAL System to provide the analytical power needed across a range
of applications, from food safety to environmental monitoring.
