Contaminant Identification and Quantification Analysis

In the case when consumers are complaining about the black spots found on transparent yogurt cups, the manufacturer would probably need to know whether the contamination came from raw material before manufacturing or it was generated during plastic production or simply was migrated from careless packaging? Manufacturers and consumers may ask the same questions like:

• Is the contamination organic or inorganic, detrimental or only affecting the appearance, long-lasting or temporary?

• Is the contamination expected to be widespread or localized?

• Is it expected to be on the surface, in a specific layer, at an interface, or in the bulk of the material?

• Is it the contaminant harmful or only matter above certain levels?

It is clear that unexpected and unaddressed contamination can have a dramatic impact on manufacturing processes and may influence consumer experiences. In industrial production, the contaminants in raw materials or unstable performance of the raw materials will also cost great loss to the manufacturers.

Alfa Chemistry is here to answer all your questions regarding contaminations. We offer Contaminant Detection, Identification, and Quantification services to consumer goods as well as advanced materials. Contaminants in some advanced materials can greatly affect their performance. TiNi, as a shape memory alloy (SMA), is becoming more and more popular in medical device applications. It can serve as a medical stent in blood vessels or transplants that need to stand repeated loading and unloading. However, contaminations can degrade the performance of TiNi by affecting its mechanical performance.
