The identification of color bodies is one of the most technically difficult challenges facing an analytical chemist. Impact Analytical's technical expert in color body identification, Dr. Norman Skelly, has solved over 40 color body problems. Dr. Skelly's considerable experience will result in a cost-effective solution to your color body problem.

The identification of color bodies usually entails the isolation of the color body to a high degree of purity, followed by mass and infrared spectroscopic identification. Several examples are listed below.

• Color in a polymer
• Color on the surface of a plastic bottle
• Color in a plastic bag or wrap
• Off-color in a formulated product
