Resum
An inter-laboratory comparison of a UV-Vis spectroscopic method (TAPPI T 282 om-13 "Hexeneuronic acid content of chemical pulp") for hexeneuronic acid measurements was conducted using three eucalyptus kraft pulps. The pulp samples were produced in a laboratory at kappa numbers of approximately 14, 20, and 35. The hexeneuronic acid contents of the three pulps were approximately 55-65 mu mol/g, or with a variation of approximately 15%. Five laboratories from four different countries participated i...
