Physical & Chemical Index Test Service

Share

Physical and chemical index is the technical index of physical property, chemical component, and chemical property, indicating the quality of the product. Creative Biomart offers comprehensive physical and chemical indexes test service on various kinds of foods, drugs and chemical products. We provide accurate and consistent analysis result with all necessary details of your sample’s physical and chemical properties.

Physical indexes can be important indicators of product quality, such as color, melting point, boiling point, volatility, solubility, density, electrical conductivity, moisture, osmotic, purity and so on. All these indexes describe the physical property of a product in detail, providing a direct cognition of the product.

Chemical indexes usually involve stability, flammability, acidity, alkalinity, oxidability, reducibility, crystal form, pH, etc. Unlike physical index, chemical index often needs to be determined by specialized experiments. Chemical index test can reveal product property at molecular level, and help scientists evaluate products’ potential effect and safety (especially for drugs).
