This method is suitable for highly refined pulps with low pentosan content. With suitable variation in size of test specimen or dilution of the distillate, or both, the method is applicable to pulps with high pentosan content and to wood.

Furfural is formed from the xylan in the pulp by the action of hot hydrochloric acid and is distilled from the mixture. The amount of furfural in the distillate is determined as the coloured orcinol complex by a spectrophotometric method.
