Determining the Whiteness of Cardboard Fiber Using the SPECORD<sup>®</sup> 250 PLUS with WinASPECT<sup>®</sup> PLUS Software.

20 Apr 2016

This application describes a method for the determination of the degree of whiteness of cardboard fiber for the pulp and paper manufacture. White is the color of purity and of cleanness and further it is actually an indicator of freedom from contaminants, and as such can be a measure of quality of the product. The measurement was carried out using the SPECORD® 250 PLUS with the integrating sphere as accessory and by means of the color module in Win ASPECT® PLUS software.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.
