Materials Testing - Pulp Testing

The final quality of a paper product is heavily influenced by the properties of raw materials, fibers and process conditions. In today’s market, with fiber resources continually changing and new fiber types and combinations constantly being developed, it can be challenging to maintain product quality and performance. The PDC can support your efforts to keep standards high by evaluating and testing the raw materials that make up the essential building blocks of your product.

Our high-tech wet labs and controlled environmental testing room provide our staff with the resources to perform many different tests to characterize the properties of pulp and fibrous raw materials for papermaking. Our staff is available to serve our clients’ needs, with tests ranging from the standard to the customized.

Pulp & Fiber Analytical Equipment


The Process Development Center has a broad range of equipment for evaluation of different kinds of raw material for pulp and paper production. We can analyze wood chips for important properties such as:

A pulp yield measurement method has been developed at the PDC: samples are collected at the mill, then analyzed for cellulose, hemicellulose, lignin content and cellulose degree of polymerization. Our researchers then calculate the total yield for the mill operation. A validated data bank for estimating pulp yield using this technique can be used to estimate the yield of a variety of wood species and various pulps, provided we know the wood furnish composition.

Additional Capabilities

To find out more about the PDC’s analytical capabilities, contact Pros Bennett, our Managing Director. After scheduling your work, visit our Shipping Information and Sample Submission pages and fill out our Sample Submission Form.
