Unexpected and unaddressed contamination can have a dramatic impact on manufacturing processes, therefore it is critical to understand and control it quickly. EAG scientists are experts at applying materials characterization techniques to search for and identify contaminants, determine their source and measure the effectiveness of contaminant removal/cleaning.
Choosing the appropriate technique or analytical approach depends upon the circumstances of the contamination event(s), the nature of the contaminant(s) and the goal of the analysis.
Often, a strategic, technical, multi-disciplinary approach is required to fully identify an unknown contaminant. The use of a comparison study between a control and suspect sample may also be helpful (or required). The specific technical approach is dependent on the sample matrix and the suspected level of contamination.
Once identification is complete, EAG scientists can further quantify the contaminant in the sample matrix by other methods or through quantification of existing data.
Typical contamination testing and identification projects have involved off-odor/flavor investigations, off-color problems, or foreign particles in a product. Some sources of contaminants have been from the environment, from improper storage of the product, or due to poor quality raw materials. We work closely with our clients to trace the source of contamination and develop a realistic corrective action program.
Listed below are many different types of contamination and potential techniques of interest to address them. The type of contamination can very much determine whether the technique used is successful. In some cases a combination of techniques may be needed, particularly if little is known about the contamination or if it is a mixture of components.
