PROFESSIONAL EXPERIENCE

7/1976 – 12/2014

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

Antek/Multitek).

Wrote JSA’s to ensure procedure were performed safely.

Trained staff on operation of equipment.

TECHNICIAN SPECIALIST (7/1976 – 12/2006)

Analyzed daily catalyst and/ or oil samples.

Performed sulfur and nitrogen content in oil samples using Antek 7000 and 9000, Horiba Sulfur Analyzer, Dohrmann

Nitrogen Analyzer, and XRF.

Utilized ASTM and Saybolt colorimeters to determine colors of oil samples.

Performed surface areas on catalysts using Micromeritics equipment.

Performed analysis of catalyst samples using XRF and XRD.

Determined pore size of catalysts using Micromeritics Nitrogen Porosimeters and Micromeritics Mercury

Porosimeters.

INOLEX PHARMACEUTICAL AND CHEMICAL COMPANY, Park Forest South, Illinois 11/1973 – 12/1975

LAB TECHNICIAN

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.
