AccuStandard has made available to laboratories a full set of standards designed for use with EPA Method 535, for method development and quality control
EPA Method 535 reference standards from AccuStandard include standards for all 12 compounds plus the internal standard and the surrogate standard, for a total of 14 compounds in the set.
EPA Method 535 is designed for the determination of six acetamide herbicides in the form of both ethanesulfonic acid (ESA) derivatives and oxanilic acid (OA) degradates in drinking water.
This method uses LC/MS/MS for both identification and quantitation.
These compounds are very difficult to analyse by gas chromatography mass spectrometry (GC/MS), the more traditional technique for environmental analysis.
This highly anticipated new EPA Method will take effect on 1 January 2008.
AccuStandard offers over 35,000 organic and inorganic chemical reference standards.
AccuStandard supplies, manufactures and also synthesises standards for the environmental, industrial and petrochemical industries.
AccuStandard's Quality System is certified to both ISO 9001:2000 and ISO 17025.
