Analysis of BTEX in Water with a CAR(WR)/PDMS 95 µm SPME Fiber
16 Jul 2019In this application note, Agilent highlights solid-phase microextraction (SPME) as a convenient technique for the analysis of volatile and semivolatile compounds in drinking water. The CAR(WR)/PDMS 95 µm SPME fiber was selected for the analysis of BTEX and MTBE in drinking water due to its selectivity for gases and low molecular weight compounds.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats. Find the best SPE, SLE and SPME equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. 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).Solid 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.
