Determination of a property of a fiber suspension

A method for determining a property of a fiber suspension, the method comprising the following steps:

• a) obtaining a sample of the fiber suspension,
• b) diluting the sample by a first dilution by adding dilution water to the sample, thereby providing a diluted sample, while retaining all of the sample obtained in step a),
• c) mixing the diluted sample using a single mixing chamber, thereby providing a mixed, diluted sample, and
• d) removing part of the mixed, diluted sample and retaining an amount of the mixed, diluted sample provided in step c),
• e) further diluting the mixed, diluted sample by adding dilution water to the retained amount of the mixed, diluted sample retained in step d), thereby providing a further diluted sample, while retaining all of the retained amount of the mixed, diluted sample retained in step d),
• f) mixing the further diluted sample provided in step e) using the single mixing chamber, thereby providing a mixed, further diluted sample,
• g) repeating steps d)-f) until the concentration of the mixed, further diluted sample is suitable for measuring the property to be determined of the further diluted sample, and
• h) measuring the property to be determined of the further diluted sample.
