Abstract

See full text

The invention relates to a method and arrangement for determining the amount of starch used in surface-sizing a cellulose product. In the solution according to the invention, the amount of starch is determined with a transmission method utilizing IR spectroscopy by using absorption wavelengths of cellulose. Absorption values are measured before adding a coating and after it, whereby the amount of starch is determined from the difference between these absorption values.
