US EPA Method 625

US EPA Method 625, consists of large suite of semivolatile analystes that may be included in wastewater discharge permit or used to ensure pristine waterways stay clean.

Horizon Technology is currently working with the US EPA and the Independent laboratories Institute to include solid phae extraction (SPE) as an option instead of liquid-liquid extraction in the sample preparation part of the method. As part of the method update rule (MUR) SPE is included in the latest version of method 625 and will continue to provide support for its full inclusion.

US EPA Method 608

US EPA Method 608 is a sensitive method for pesticide analysis. Although GC/MS method 625 also includes a variety of pesticides, 608 is sometimes more sensitive, using an ECD for specific detection. Horizon Technology helped with an alternate test procedure (ATP) study to include SPE for sample preparation for method 608, which was accepted in 1995. In the latest MUR, SPE is being written directly into the method so it will no longer be necessary to refer to the ATP document.

EPA Method 1664, 1664A and 1664B

US EPA Method 1664, 1664A and 1664B and SM 5520G are the revised n-hexane extractable Oil & Grease methods developed after the Montreal Protocol phased out the use of chlorofluorocarbons to protect the ozone layer. Horizon Technology offers a number of support materials for these methods.
