Moisture Plus Solutions for Polymer Production

Material ID and Qualification

When the goal is to meet material performance specifications or prevent bad production runs, knowing what the starting and ending materials are is key. Metrohm Moisture Plus NIR systems provide the confidence necessary to move forward with production, or release product to customers.

NIR methods for identifying and qualifying starting materials, as well as final products are recognized by ASTM International. Metrohm Applications Specialists can help ensure your analysis complies with NIR Standard Practices E1655 and E1790 for the best results.

  • AN-RS-008 – Identification of monomers with Raman spectroscopy

At-line and Laboratory Analyzers

Metrohm bench top NIR analyzers make polymer analysis fast and easy. Traditional end group analyses by titration require hours to dissolve the polymer, use toxic chemicals, and may produce variable results because of the numerous steps involved. With Moisture Plus analysis, accuracy goes up, time goes down, and solvents are eliminated.

Our IP65 rated dustproof enclosures and vibration insensitive grating spectrometers are equally well-suited to the lab or at the production line.

Measurement is as simple as placing the polymer in the dedicated sampling accessory and pressing “go”.

Measure moisture in: Solvents, precursors, viscous liquids, pellets, and fibers

Typical Moisture Plus applications: Acid value; additives; amine value; blend composition; branching; carboxyl end group; cure and melt index; density; hydroxyl number; isocyanate; molecular weight; residual solvents, additives, and monomers; softening point; tacticity; viscosity

Process Monitoring Technology

Online Moisture Plus NIR spectroscopy brings all the capabilities of laboratory analysis to the production line. Rather than waiting hours for lab results, the same analysis can be completed within seconds and sent directly to the production control center. With Moisture Plus Process NIR, determine the endpoint of a reaction in real-time and reduce the over-processing of products. This improves production consistency, increases capacity, and reduces per-batch costs.

Beyond moisture monitoring, some typical Moisture Plus process applications include: Reaction monitoring, extrusion melting, polymer curing, and solvent recovery
