Lyza Series FTIR spectrometers Turn polymer spectra into decisions

Anton Paar’s Lyza series FTIR spectrometers provide a powerful plastics analysis platform for polymer manufacturers, compounders, masterbatchers, converters, and recyclers.

Raw-material mix-ups, filler drift, contamination, oxidation, cure state, and recyclate variability cannot be resolved by visual inspection alone. The Lyza series combines molecular identification, verification, and quantification with guided workflows to help turn polymer spectra into decisions—from incoming goods inspection to formulation control and aging studies.

Lyza takes users from measurement to a pass/fail result in just three steps. Designed for straightforward routine QC, Lyza 7000 enables standalone operation through its integrated touchscreen. Lyza 3000 delivers the same core analytical capability in a more cost-conscious setup and is operated via the AP Spectroscopy Suite desktop software.

In Anton Paar application studies, the Lyza series was used for verification of incoming LDPE, PEEK intermediate products, and EVA copolymers. The same FTIR workflow delivers a direct pass/fail decision, helping labs release conforming lots faster and isolate non-conforming material before it moves downstream.

The Lyza series quantification feature can convert spectra into actionable numbers for additives and fillers, such as calcium carbonate (CaCO3) in LLDPE. Linear calibrations can also be created for polypropylene in polyethylene (according to ASTM D7399). This supports formulation and recipe development by verifying composition against targets and enabling confident adjustments.

For R&D and failure analysis, FTIR spectroscopy can track UV- and ClO2-driven oxidation in polyolefins via carbonyl, hydroxyl, and carboxylate bands, and monitor epoxy-amine curing through the disappearance of the oxirane band. This extends the range of FTIR applications beyond routine QC into process development, lifetime assessment, and recycled-material qualification.
