Sample preparation before testing Obtaining a representative pulp sample is critical. Production volumes in pulp and paper making are huge. Significant variation in the process always exists. One reason for this is the variation in raw material properties (wood quality). Since the necessary sample is typically extremely small compared with the production of a mill,
