Performance testing of a detergent is typically done on a cotton swatch or other textile sample, which is stained with any number of substances from grass to coffee and tea, put through a wash cycle, and then measured to determine the cleaning power of the detergent. The preferred measurement technique for this application is to use a directional reflectance instrument, preferably diffuse d/8 ° geometry, which allows both specular included and specular excluded measurements.
Many of HunterLab's spectrophotometers are versatile enough to accommodate most applications of color measurement. However, based on 60+ years of experience and a thorough understanding of our customers' needs and product use, these particular instruments are most suited for this industries application.
If you are unsure which instrument type is right for your samples, please call or email HunterLab technical support and we will be happy to assist you in making the proper instrument selection.
