Simplifying caprolactam quality control with Abbemat Refractometers

Maximise caprolactam recovery, improve process efficiency, and verify caprolactam concentration within seconds with Abbemat refractometers from Anton Paar. Anton Paar’s Abbemat series delivers fast, reliable concentration data of aqueous ε-caprolactam solutions using just 1 mL of sample and minimal preparation.

Whether in caprolactam production, Nylon-6 manufacturing, or chemical recycling, Abbemat enables efficient process control from recovered monomer streams to final quality verification.

Abbemat laboratory refractometers and Anton Paar’s L-Rix inline refractometers allow reliable caprolactam concentration control. Laboratory measurements from an Abbemat serve as a reliable reference for method development, process optimisation, and validation of inline measurements. 

“Caprolactam recovery requires concentration data that is both fast and reliable. With Abbemat, laboratories can verify aqueous ε-caprolactam streams within seconds and generate the reliable reference data required to optimise processes and validate L-Rix inline measurements. The rapid availability of results enables operators to respond to process deviations immediately, minimising off-spec production and reducing material losses,” says Dr Frank Gottsleben, Product Manager for the Abbemat Series at Anton Paar.

Abbemat laboratory refractometers simplify routine caprolactam analysis. For defined aqueous caprolactam streams, Abbemat provides a fast, low-maintenance alternative to more complex analytical techniques such as HPLC, titration, or spectroscopy.

Customised concentration calibrations adapt concentration measurements to specific process requirements, temperatures, and concentration ranges.

From routine laboratory analysis to validation of inline measurements, Abbemat provides the reliable concentration data needed to optimise caprolactam recovery and process efficiency.
