Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic solvents (e.g., polar contaminants from sample extracts).
View Product Information Method-specific performance for extractable petroleum hydrocarbon (EPH) analysis of soil and water samples. Complete separation of aliphatic and aromatic compounds into distinct fractions. Guaranteed background level under the strict reporting limits of MA and NJ EPH methods. Superior lot-to-lot reproducibility and storage stability ensured by rigorous QC testing and moisture-resistant packaging. View Product Information High quality anhydrous sodium sulfate. Approximately 2 grams prepackaged in a convenient capped cartridge with both male and female luer ends for easy connection to a variety of devices or equipment. The adsorbent is fully activated and ready to use for removal of excess water from organic solvent solutions, prior to many types of analysis. Capped cartridges will remain active for long periods of storage in the lab. View Product Information High adsorbent capacity (surface area ~200 m /g) for large volume sampling. 2 Chromatographic grade graphitized carbon provides consistent and quantitative recoveries of a wide variety of semivolatiles, pesticides, and herbicides. 500 mg bed weight.
