Solid phase extraction of organochlorine pesticides and PCBs by EPA Method 608.3
4 Aug 2025This guide outlines a modified solid phase extraction procedure using UCT's large ID C18 cartridges for organochlorine pesticides and PCBs in water, compliant with EPA Method 608.3. The method enhances recovery, avoids clogging, and eliminates the need for sodium sulfate drying and solvent exchange by using acetone/n-hexane elution.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Analytic ChemistrySolid Phase Extraction (SPE)Solid phase extraction (SPE) is a sample preparation technique used to separate and concentrate analytes from complex mixtures. It is widely used in environmental, pharmaceutical, and clinical analysis. SPE provides higher sensitivity and selectivity compared to traditional liquid-liquid extraction methods, making it essential for accurate and reproducible results. Explore SPE tools and systems in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.PesticidesPesticides are used to protect crops from diseases, pests and unwanted plants. They are classed as persistent organic pollutants (POPs) and can be harmful to humans. The Environmental Protection Agency (EPA) currently regulates the use of pesticides in the USA.
