Phenolic Calibration Standards for Monitoring Wastewaters

Reporter US Volume 28.3

Phenolic compounds are important raw materials for the manufacturing of phenolic resins, pharmaceuticals, laboratory reagents, dyes, germicidal paints, and general disinfectants. Due to their toxicity to both man and animals, manufacturers using these raw materials may be required by local or regional government regulatory agencies to monitor wastewater discharges for these materials. Analysis of these compounds at low levels in waste effluents can be complex, requiring extensive sample preparation, followed by gas chromatography (GC). High-quality analytical standards are essential for routine daily calibration of the GC instrument.

Sigma Aldrich offers high-quality analytical phenol and substituted phenol standards in the form of neats, singlecomponent solutions, and multi-component solutions. These standards are suitable for use when monitoring phenolic compounds in accordance with the United States Environmental Protection Agency, the Canadian Ministry of Environment and the European Union environmental contaminant methodologies. The single and multi-component calibration standards are tested for purity, identity, and concentration. Each component is guaranteed to be within 0.5% of the stated concentration. Documentation is provided free-of-charge for all neat reference materials and calibration solutions.

The table below lists a sampling of the many phenolic calibration standards and neat reference materials available from Sigma- Aldrich. Additional calibration standards can be found by visiting us online at sigma-aldrich.com/standards

If you prefer, we can also formulate, test, and package phenol calibration standards per your specifications in a relatively short time, saving you valuable time and resources.
