Color measurement of powdered fertilizers with the ColorFlex EZ

Color measurement-from-flourIn 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.

Color measurement of flour powderThe 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 glass cuvette for the color measurement of powder samples. By measuring the sample from below through the glass base, you have a perfectly flat and homogeneous measuring surface. The cuvette aperture of the ColorFlex EZ also ensures that the cuvette always sits reproducibly and centrally above the aperture. The degree of whiteness WI E313 can be displayed directly on the screen.

The measurement is very simple:

  • Replace the standard aperture once with the cuvette aperture and standardize the device with it
  • Fill the product into the cuvette
  • Place the cuvette on the aperture
  • Trigger measurement at the touch of a button
  • Read off values

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...
