GRACE DAVIDSON, Chicago, IL
The site is dedicated to inorganic chemical manufacturing, specializing in industrial catalyst production. Catalysts are used in
petroleum refining and specialty petrochemical industries to remove impurities from crude oil streams to reduce the pollutants emitted
during refining and consumption of gasoline and other petroleum based products.
SENIOR TECHNICIAN SPECIALIST (1/2007 – 12/2014)
Efficiently and accurately analyzed daily oil samples and customer oil or catalysts samples as required.
Analyzed sulfur and nitrogen content in oil samples using Antek 9000 and PAC Multitek.
Established density of oil samples using Mettler and Anton Paar density meters.
Verified aromatics in diesel oil samples using Waters HPLC.
Ascertained boiling range of samples using Analytical Controls and PAC simulated distillation gas chromatographs.
Extracted and regenerated spent catalyst customer samples.
Performed cloud point and NMR of oil samples and micro carbon residue testing of oil samples.
Wrote and maintained up-to-date methods on equipment operations (Multitek, Antek, density meters, extraction and
regeneration, MCRT, HPLC, simdis, ASTM and Saybolt colors, regeneration oven and autosamplers for
Wrote JSA’s to ensure procedure were performed safely.
Trained staff on operation of equipment.

INOLEX PHARMACEUTICAL AND CHEMICAL COMPANY, Park Forest South, Illinois 11/1973 – 12/1975
Analysis of the binding of antigen-antibody complexes using the technique of radioimmunoassay was performed.
With the use of a liquid scintillation counter, the binding of a radioactive antigen was determined. Antibodies to
several hormones and samples from hospitals containing the hormones were tested.
