Analytical Method Development
Gossman Consulting Inc. (GCI) personnel
developed a number of analytical methods over the last 20 years. A
these methods have been formally adopted as ASTM methods. GCI continues
refine these methods and frequently assists our clients in adapting
other laboratory testing methods to the plant and matrix specific needs
clients. We are frequently called upon to troubleshoot laboratory
that are not meeting data quality objectives.
- Designed and set up a new GC/MSD
system for testing organic hazardous waste using the latest available
- 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
- 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
- Developed the first XRF method, for
determining metal concentrations in organic hazardous wastes, used at a
- 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
GCI has prepared a number of papers on analytical method
of these methods were developed to quickly and efficiently analyze
hazardous waste. Experience with the complexities of determinations in
matrix allow us to develop solutions for numerous other matrices.
