  • Increased laboratory productivity for ICPOES applied to U.S. EPA method 6010C

    The use of an ESI SC FAST autosampler coupled to a Perkin Elmer Optima 7300 DV ICP can dramatically improve productivity for the analysis of environmental samples using EPA SW-846 Method 6010C. Sample throughput, as determined by sample-to-sample run time can be improved by as much as 100% as compared to traditional sample introduction systems and autosampler configurations. Both sample analysis ...

  • EPA Method 415.3 - Determination of TOC in Source Water and Drinking Water

    Method 415.3 states that the measurement of Total Organic Carbon (TOC) and DOC must use a TOC instrument that oxidizes organic carbon in the water to create carbon dioxide gas, which is then measurable. The instruments are required to use one of two basic oxidation methods – either through combustion with an oxidizing gas, or through chemical oxidation with persulfate promoted by either UV ...

  • US EPA Method 515 Chlorinated Acids on Equity-1701

    The potential health effects associated with many chlorinated acid herbicides has led to regulations regarding their use. US EPA method 515 describes the GC/ECD analysis of these compounds as their methyl ester derivatives in ground and drinking water, and lists a 1701-type capillary for use as a secondary column. In this application, 15 out of the 16 herbicides listed in method 515 were resolved ...

  • Trace Analysis of PAHs using EPA methods 3541, 3545 and 8100

    The Extraction System B-811 and the Syncore Analyst parallel concentrator from Buchi as well as the Pressurized Solvent Extractor from Applied Separations were evaluated for the pretreatment of samples containing PAHs. Recoveries of extraction and subsequent concentration using acetone-n-hexane (1+1) were 70-95% for 2 ring and 90-100% for less volatile 3-5 ring PAHs. A good precision (95% ...

  • Will the equipment match the regulatory method?

    Anyone involved in field analysis of oil in water will con tinually get the question "Does your equipment match the regulatory method?" Zj While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory ...
