Sample preparation, or sample prep, is an essential part of chromatographic and spectroscopic analyses. The purpose of sample prep is to convert the sample into a form suitable for analysis without significant loss of target compounds. Proper sample preparation removes potentially interfering contamination, which extends the lifetime of your chromatography column and other instrument components.
Agilents suite of sample preparation products ensure you have the right product for your needs. Our purification and filtration products provide quick and reliable results for repeated analyses and are ideal for busy, high-throughput laboratories. Pre-packaged QuEChERS extraction and dispersive solid phase extraction (dSPE) kits are ideal for food samples and accommodate AOAC and EN methodologies. We also offer a full portfolio of solid supported liquid extraction (SLE), solid phase extraction (SPE), and solid phase microextraction (SPME) products in various chemistries and formats to achieve excellent performance and ensure samples are free of interferences, even with complex matrices.
QuEChERS eSelector provides extraction and dispersive kit recommendations for pesticides in fruit and vegetables.

The SPME Arrow – Intuvo GC – MS/MS system incorporates maximum precision coupled with a speed that is not achieved with any other technology. According to the studies of J·Vigas, there is no other equipment on the current market for the analysis of TCA in wine stoppers that gives such reliable results in 5 minutes.
Agilent won a 2023 Environment+Energy Leader Award for Bond Elut PFAS WAX SPE Cartridges that improve efficiency in testing for PFAS substances, the so-called ‘forever chemicals.’ Bond Elut PFAS WAX enables scientists to confidently isolate PFAS from drinking water, wastewater, soil, sludge, tissues, and food.
“The presence of PFAS chemicals in our daily lives is a grave concern,” the judges wrote, “making any technology that aids in their removal from the environment truly lifesaving.”
Agilent announced a highly-anticipated, complete workflow solution for targeted per- and polyfluoroalkyl substances (PFAS) analysis using the United States (US) Environmental Protection Agency (EPA) Method 1633 (3rd draft). EPA Draft Method 1633 currently analyzes 40 PFAS compounds in wastewater and soil and is a complex and labor-intensive method, relying on multiple sample preparation and analysis steps. Success in running the technique depends on careful sample handling and the appropriate sample preparation supplies and instrumentation.
Concerns about trace level pollutants in food are driving demand for more rapid and reliable ways to identify and quantify chemical residues. One measure of food safety is the maximum residue limit (MRL), which is the highest level pf pesticide residue allowed to remain in or on the treated food commodity. This article highlights five ways to ensure successful pesticide analysis.
