Color measurement of solid and powdery chemical products

Powdered chemicals are used in numerous industries such as the coatings, food, building materials, pharmaceuticals, plastics, cosmetics and detergents industries, to name but a few. Yellowness (Yellowness Index YI), whiteness (Whiteness Index WI), color fastness and also UV resistance, e.g. of pigments and fillers, flakes for paints, superabsorbents, granulates, resins and powder coatings are tested.

The world’s leading chemical manufacturers rely on HunterLab solutions to ensure the quality and consistency of finished products and raw materials throughout their supply chains with accurate and repeatable measurement results.

Application example:

Color measurement of powdered fertilizers with the ColorFlex EZ

In the fertilizer industry, whether powdered natural fertilizers, mineral fertilizers or animal meal, the color of a product is usually directly related to its quality. HunterLab offers suitable measurement solutions to precisely determine the color quality of fertilizers and fertilizers in production. In particular, it is possible to determine the degree of whiteness WI according to ASTM E313 when using white products such as calcium carbonate or magnesium sulphate. The task Precise colour measurement of powdered fertilizers with optional determination of the degree of whiteness WI E313. The solution HunterLab recommends the ColorFlex EZ spectrophotometer and the use of a 64 mm optical...

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
