Analytical Method Development

Service Description

Gossman Consulting Inc. (GCI) personnel have developed a number of analytical methods over the last 20 years. A number of these methods have been formally adopted as ASTM methods. GCI continues to refine these methods and frequently assists our clients in adapting these and other laboratory testing methods to the plant and matrix specific needs of our clients. We are frequently called upon to troubleshoot laboratory procedures that are not meeting data quality objectives.

Experience

David Gossman:

• Designed and set up a new GC/MSD system for testing organic hazardous waste using the latest available technology.
• Developed a detailed GC-MSD technique for determining volatile and semivolatile organics in hazardous waste fuel. The technique is now being used in at least three hazardous waste fuels laboratories.
• Developed quick, easy to use pair of screening techniques for testing organic hazardous waste for free cyanides and sulfides.
• Co-developed a method for screening organic hazardous waste for reactivity.
• Developed sample preparation methods for homogenizing non-homogeneous samples of liquid and solid HWF prior to analysis.
• Developed the first XRF method, for determining metal concentrations in organic hazardous wastes, used at a commercial facility.
• Developed and wrote a screening method for radioactive material contamination of HWF.
• Developed laboratory testing methods to screen HWF for selected pesticides.
• Developed laboratory operating procedure that allows for the determination of sub-ppm levels of mercury in HWF in less than two hours using EPA SW-846 methodology.
• Developed and published the first high speed methodology for determining metals in HWF utilizing organic matrix dilution and direct aspiration into an atomic absorption spectrophotometer. Developed and published the first analytical methodology to utilize ion chromatography to determine F, Cl, Br, S, and P in HWF.
• Developed and published the first analytical methodology specifically designed to determine PCBs in HWF. The method was eventually expanded to utilize computerized, graphics based pattern recognition.

Relevant Publications

GCI has prepared a number of papers on analytical method development. Most of these methods were developed to quickly and efficiently analyze organic hazardous waste. Experience with the complexities of determinations in this matrix allow us to develop solutions for numerous other matrices.

• The Analysis of Flammable Industrial Wastes Using Ion Chromatography
• Data Processing as an Alternative to Extensive Sample Clean up in the Gas Chromatographic Determination of PCBs
• The Determination of Metals in Paint and Paint Wastes using Atomic Absorption and Emission Spectroscopy
• A Method for the Rapid Semi-Quantitive Identification of Hazardous Organic Constituents in Liquid Organic Hazardous Waste Streams
• HWF Notes "Testing for Pentachlorophenol as a Screening Procedure to exclude PCDD's and PCDF's from Hazardous Waste Fuel", Dec-93
• HWF Notes "Standard Practice for the Microwave Digestion of Industrial Furnace Feedstreams", Jan-94
• HWF Notes "Method for Screening Radioactivity in Waste", April-92
