Analyze Carbamate Pesticides in a Fraction of the Time and Boost Productivity
13 Nov 2018Carbamate pesticides are widely used insecticides that pose human and environmental health risks due to their activity as endocrine disruptors. While many pesticides can be analyzed successfully using GC, carbamate pesticides are thermally unstable and degrade quickly in the hot GC inlet. Therefore, LC methods must be used to monitor levels of these semivolatile compounds in soil and water samples. C18 columns can be used for carbamate pesticides analysis, but traditional methods—such as EPA Method 531—require analysis times of over 20 minutes.

Ultra Carbamate Columns
Restek Corp.Restek chemists developed the Ultra Carbamate column specifically for carbamates analysis. The unique packing separates 10 target carbamates in just 5 minutes with an 8 minute total cycle time. The column is compatible with fluorescence or LC-MS detection.* An Ultra Carbamate column can process as many as eight samples per hour, versus less than two samples per hour on a general-purpose C18 column. In addition to increased sample throughput, this much faster analysis will significantly reduce solvent usage—and the costs of disposing of solvent waste. Refer to featured application EVSS2394-UNV for more information. Particle: 3 μm or 5 μm, spherical Pore Size: 100 Å Carbon Load: proprietary Surface Area: 300 m2/g pH Range: 2.5 to 8 Maximum Temperature: 80 °C For post-column derivatization/fluorescence detection applications using a 4.6 mm ID column, the total system dead volume, including the post-column reactor, must be less than 650 μL. For standard post-column reactor systems, we recommend a 250 mm x 4.6 mm, 5 μm column. Contact Restek Technical Service or your local Restek representative for more information.
