Processes for rapidly and accurately measuring the coefficient of moisture expansion for materials, such as adhesives, are disclosed. A replication technique may be used to manufacture highly flat and smooth adhesive samples. Moisture is introduced in a controlled humidity atmosphere, distortion is monitored with an accurate laser interferometer (e.g., ?1 nanometer (nm) accuracy), and measurements are correlated with moisture content change. Such processes decrease sample size by three orders of magnitude as compared with conventional techniques and have a smaller adhesive mass requirement, which enables measurement of expensive microelectronic adhesives that were previously cost-prohibitive to measure. Also, thinner films allow CME measurements of ultraviolet (UV) cured adhesives that would otherwise have depth of penetration issues. Furthermore, saturation occurs quickly, allowing pre-stabilization at room temperature, which enabled parametric studies as a function of processing or cure state. Additionally, testing occurs within hours versus months, enabling short lead times for root-cause investigations.

The analyzer of the present invention is specifically adapted to provide moisture determinations for foods and other agricultural material. It allows the operator to introduce a precise weight of sample into a crucible in a closed furnace in a controlled environment through an access port in the furnace cover. The access port in the cover can be tapered to allow easy access to an underlying aligned crucible and allow an operator to add and remove sample material from the crucible until a precise desired sample weight is reached as measured by a balance within the furnace. The access port is enclosed by an insulated cover after the samples are sequentially placed in the crucibles.

The invention relates to a method for determining properties of hygroscopic material in real-time during modification wherein, in the method, pieces of hygroscopic material to be modified are stacked and a batch of the hygroscopic material (15) being thereby formed is placed in a modification chamber (11) of a modification apparatus (10) wherein the pieces of the hygroscopic material to be modified are modified. In the method according to the invention at least weight, volume, amount of water in the batch of the hygroscopic material as well as average moisture content of the batch of the hygroscopic material (15) are determined before modification and/or at least once during and/or after modification of the batch of the hygroscopic material (15). The invention relates also to an apparatus for determining properties of hygroscopic material in real-time during modification of the batch of the hygroscopic material (15).
