MEDICAL DIAGNOSTIC TEST FORMULATING; ORGANIC SOLVENT; SEMISYNTHETIC POLYMER. Expert has spent 21 years engaged in adapting analytical techniques to the quantitative analysis of medically significant substances. This has involved combining pH buffers, enzymes, chromogens, and stabilizers to make a marketable test. Specifically, Expert has worked on tests for blood glucose, urinary glucose, ketones, nitrite, specific gravity, bilirubin, urobilinogen, protein, and pH. These tests use water and organic solvents to convey dye forming compounds such as benzidines, amines, phenolic compounds, and organometallics into a semisynthetic polymer matrix. The dyes thus formed are usually quinones and can sometimes be converted into pigments. The polymer matrix can be natural, such as paper, or something formed by anionic, cationic, or free radical polymerization.

DIAGNOSTIC REAGENT. Expert has spent the last 24 years formulating medical diagnostic tests. These tests always have a pH buffering component and are for the most part interpreted using a visual color matching scheme. The tests use synthetic, semi-synthetic, or natural polymers as stabilizers and after require the use of organic solvents and detergents to produce a marketable product.

COMMISSION INTERNATIONALE DE L'ECLAIRAGE (CIE) COLOR ANALYSIS; INORGANIC PHOTOCHEMISTRY. The polymer rheology determines how the test sample will be imbibed and thus affects the result. Expert has found that stabilizing these tests is sometimes difficult and can involve inorganic photo chemical reactions. These tests are read visually or by reflectance, which requires work with CIE Color Analysis. He has worked extensively with CIE Color Analysis, having done this continuously for the past 18 years. Expert has lectured on the stabilization of solid phase tests. He has a knowledge of the organic synthesis of dyes in a solid phase. He is very knowledgeable of organometallic chemistry and organic solvents. He has extensive experience in inorganic photochemistry, as well as with emulsion, anionic, cationic, and free radical polymerization. Expert is also a good source to turn to for questions dealing with medical product packaging. He has also had experience using clays as water and odor absorbers as well as using free radical initiators as catalysts.

Expert may consult nationally and internationally, and is also local to the following cities: Indianapolis, Indiana - Fort Wayne, Indiana - Bloomington, Indiana - Muncie, Indiana - Anderson, Indiana - Terre Haute, Indiana - Lafayette, Indiana - Cincinnati, Ohio - Dayton, Ohio - Hamilton, Ohio
