Color measurement of solid and powdery chemical products

 

Powdered chemicals are used in numerous industries such as the paint, food, building materials, pharmaceutical, plastics, cosmetics and cleaning products industries, to name just a few. The degree of yellowness (Yellowness Index YI), degree of whiteness (Whitenes Index WI), color fastness and also UV resistance, e.g. B. of pigments and fillers, flakes for paints, superabsorbers, granules, resins and powder coatings.


The world's leading chemical producers rely on HunterLab solutions to ensure the quality and consistency of finished products as well as raw materials used across their entire supply chains with precise 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, the determination of the whiteness WI according to ASTM E313 when using white products such as: B. calcium carbonate or magnesium sulfate possible.

The task

Exact color 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 to measure the color of powdered samples. By measuring the sample from below through the glass bottom, you have a perfectly flat and homogeneous measuring surface. The ColorFlex EZ cuvette cover also ensures that the cuvette is always reproducible and sits centrally above the cover. The whiteness WI E313 can be displayed directly on the screen.

The measurement is very simple:

    Replace the standard aperture with the cuvette aperture once and standardize the device with this. Fill the product into the cuvette. Place the cuvette on the aperture. Trigger the measurement with the push of a button. Read the values
