用于测量悬浮液的方法和测量设备
摘要：
本发明涉及测量包含木纤维的悬浮液的方法。在浓度范围内改变悬浮液的浓度(100)。将使用第一光学波长和第二光学波长的光学辐射引导在悬浮液处(102)。针对至少一个给定的浓度值来确定与第一光学波长相关的光学辐射的第一强度值和与第二光学波长相关的第二强度值(104)。确定第一强度值和第二强度值的比率(106)。确定悬浮液的卡伯值(108)。通过将预定因子应用于第一强度值和第二强度值的比率，获得己烯糖醛酸HexA的原始值(110)。通过将确定比率与卡伯值相乘，确定悬浮液中HexA的含量(112)。
摘要（英）：

The invention relates to method of measuring a suspension which contains wood fibres. The consistency of the suspension is changed (100) in a consistency range. Optical radiation using a first optical wavelength and a second optical wavelength is directed (102) at the suspension. A first intensity value of the optical radiation related to the first optical wavelength and a second intensity value related to the second optical wavelength on at least one given consistency value is determined (104). The ratio of the first and second intensity values is determined (106). Kappa number of the suspension is determined (108). A raw value for hexenuronic acid, HexA is obtained (110) by applying predetermined factors to the ratio of the first and second intensity values. The content of HexA in the suspension is determined (112) by multiplying the determined ratio with the kappa number.
