Composition Analysis
Composition Analysis

Composition analysis enables us to identify or quantify the concentration of a substances, multiple substances or unknown substances in a sample by utilising separation and analytical methods, which gives us a full picture of a sample.

Why Should We Do Composition Analysis?

Failure Analysis. Understanding the composition of products helps us to know the underlying issues of defective products for improvement.

Deformulation. It is a good approach to learn about the formulation of new products and then mimic the manufacturing of products.

R&D and Continuous Improvement. Comparing the composition of our products with that from a potential competitor or new vendor of the product provides support for R&D and continuous improvement.

Composition identification. It confirms the identity of a suspected material.
