Chemist, Analytical chemist
and
college professor.
Contact: e-mail: crawfork@uwosh.edu
Capabilities: Quantitative and
qualitative analysis, any sample size and type. Specializing
in
water analysis, but also able to handle many other sample
types.
From simple wet chemical analysis (titrations, gravimetric analysis)
to
full instrumental analysis (GC-MS, HPLC, FTIR, AA), I can help find
the
answers to your chemical problems.
Consulting Experience:
Development of
SPME-GC-MS
method to test for extractables in a plastic
material
(company confidential).
Development of a SPME-GC-MS method for
quantitation
of several
compounds
of
interest for Fine Northern Oak, Berlin, WI.
Analysis
of filter material pore sizes by SEM for W.M. Nugent Co.,
Niles,
IL.
Analysis of filter-captured material to identify cause of electrical
failures in manufacturing equipment (company confidential).
Development of a simple
inexpensive method for quantitation of surfactant levels in cleaning
solutions for WI Film and Bag.
Determination
of metal cations by AA for the South Carolina Aquarium,
Charleston, SC..
Quantitation
of calcium, sodium, and boron in a marine extract via AA
for
the National Ocean Service Marine Biotoxins Program, Charleston,
SC.
Other Experience:
Utilizing
EPA methods for water and sediments - for the analysis of
many
components
in natural waters - metal cations, anions, pesticides, etc.
GC-MS
identification and quantitation of phthalates, drugs of abuse,
constituents
in oil and gas, PCB's and PBDE's, dioxins, insecticides
and
pesticides.
HPLC
identification and quantitation of caffeine, organic acids,
chlorophyll,
aspirin,
etc.
AA
and GFAA quantitation of metals in water and sediment.
Instrumentation available:
GC-MS (gas chromatography mass
spectrometry)
- quadrupole system with headspace, liquid, and SPME sample
introduction.
HPLC (liquid chromatography) system -
gradient solvent capability, fluorescence, diode array, and ELSD
detection, many column types available including
C8, C18, amide-C16, size exclusion (GPC), anion exchange.
LC-MS - gradient solvent, single
quadrupole
Atomic Absorption - suitable for
analysis of most metals. Also equipped for graphite furnace
AA..
FTIR (infrared) systems - for
identification
of organic compounds.
Multiple UV-visible units - for
ultraviolet
and visible light absorbance measurements.
GC-FID (gas chromatography) instruments
- used for volatile organic compounds.
Scanning Electron Microscope - including
gold and carbon coating of samples.
X-ray (XRF)
- for
analysis of metal composition in samples.
Several pH meters and electronic balances.
Standard lab equipment and glassware for
quantitative analysis.
Analytical chemical standards for
quantitation and verification.
