Technical Problem-Solving for Materials and Processes

ID: 107647 Minnesota, USA

Request Expert

Expert has extensive experience in both gas and liquid chromatography. He has studied theoretical mechanisms of separation and published application techniques in environmental and biological areas. Skilled in the use of data acquisition and data handling systems, Expert is particularly adept with the analysis and interpretation of chromatography data. He has some recent experience in supercritical fluid extraction and chromatography.

Expert has developed numerous methods based on chromatographic separations. Methods have been developed for analytes in both environmental and biological matrices, as well as active ingredients in various formulations. These methods have reliably determined analytes at the part-per-million, part-per-billion, and even part-per-trillion levels. His method for determining formaldehyde in environmental samples has been published by the US EPA as Method 8315.

Expert has many years of experience in troubleshooting HPLC systems and methods. He can diagnose both mechanical instrument and chemical method problems and make repairs or corrections as necessary. He has developed and presented training courses on chromatography troubleshooting.

Skilled in all aspects of quantitative analysis, Expert is an expert in determining trace levels of impurities, active ingredients (major percentage), and complete characterization (mass balance) of formulations. He has used chromatographic, spectroscopic, and wet chemistry techniques.

A significant portion of Expert's career has been devoted to experimental design. He has published articles on application of experimental design strategies for optimizing analytical methods. He has studied the application of design of experiments (DOE) in gas chromatography, liquid chromatography, and supercritical fluid extraction.

Expert is knowledgeable of all areas of supercritical fluid extraction (SFE). He has published and presented results on the application of SFE to extraction of dioxins, PCBs, pesticides, amines, hydrocarbons, and phthalates. He has determined these analytes in soils, waters, feeds, and plastics.

As part of his method development experience, Expert is adept at designing procedures for effectively removing components of interest from sold samples.

Expert has extensive experience in all aspects of analytical chemistry, with an emphasis on organic-analytical techniques. He has taught analytical chemistry courses at the college and graduate level, developed training courses for laboratory staff, managed technical analytical groups, and consulted with a wide variety of industries on numerous topics.

Expert has developed numerous extraction procedures in his work as an analytical chemist. He also develops and presents training courses on sample preparation.

The correct answer to an analysis problem only results when you choose the correct technique. Expert’s extensive experience in a variety of techniques (separations: HPLC and GC; SFE/SFC; FTIR; SEC/GPC; SEM; etc.) allows him to select the most appropriate analytical approach. The solution to most problems should start with the question, "What is the problem?"

Expert has considerable experience helping medical device manufacturers develop and market their products. Device development activities have included: materials selection for components; materials characterization and extractables testing; design of shelf life experiments; and preliminary feasibility testing. Expert also participates in the regulatory approval process, including: preparation of technical data and literature summaries; review of submissions; and technical writing and reviewing. Once the product is in production, Expert assists in optimizing processes, designing process validation experiments, and solving production problems.

Expert wrote and edited technical documentation, technical summary, characterization, risk assessment, literature review, etc., in support of submission by medical device manufacturers for CE marking. CE marks were awarded to each manufacturer.He assisted a manufacturer in understanding the cause of plastic component field failures. He coordinated analytical testing, interpreted results, suggested failure modes and worked with a multi-disciplinary team.He reviewed analytical capabilities and QC program for a major gas manufacturer. Expert recommended technology changes as well as philosophical changes in the entire QA/QC program.He provided on-site training to customers in pharmaceutical, food, and testing industries. He customized his presentations to meet the needs of individual laboratories.He provided expert advice to a law firm representing a medical device manufacturer in a patent infringement suit. He reviewed testing and reports, and prepared for trial testimony. The case was settled pre-trial in favor of the medical device manufacturer.
