Multi-parameter analysis of polymers with near-infrared spectroscopy (NIRS) Faster quality control along the production cycle of bulk material to final product





NIRS for increased productivity 02

Multi-parameter analysis of polymers becomes faster and easier with Metrohm NIR solutions. From

­incoming­material­inspection­to­final­product­control,­Metrohm­NIR­solutions­give­you­confidence­in the quality of your polymer products along the entire production cycle.

To this day, manufacturers of plastics and polymers rely Metrohm offers NIR solutions for fast and reliable routine for the most part on physical and wet chemical methods quality control of feedstock, intermediates, and final proto monitor the quality of their product. Due to the time ducts in the polymer industry. Metrohm NIR solutions consuming nature of these me thods and the infrastrucrequire no chemicals for analysis, can be directly applied ture (laboratory) and costs (che micals, consumables) in the quality control process by anyone. The reliable involved, these methods can ne ga

Metrohm NIR solutions for polymer analysis means ...

Plastics Producer

• Accurate results for multiple parameters in a matter of seconds

­ A single measurement provides information about several physical and chemical parameters

• Lower costs compared to wet chemical methods

­ No chemicals and reagents required, hence also no costs for waste disposal

• Straightforward and safe operation with­no­environmental­impact­at­all

­ Solvent free analysis, analyzer can be operated by any personnel

Examples of NIR application

• Quality Control of produced polymer

• Quick method for R&D and Pilot Plants

• Atline checking of polymerization process Offline­(in­the­laboratory),­atline

NIRS analyzers for offline, atline, or online use. These are operated by the proven, intuitive Vision Air soft ware analyzers cover the near­infrared (800­2500 nm) and the enabling even users with little expertise to perform the visible wavelength (400­800 nm) range, which means analysis with a few mouse clicks. The results of multiple parameter are obtained and displayed simultaneously.

Metrohm NIR Polymer Analyzer The Polymer Analyzer is a dedicated analyzer for the analysis of polymers. The measurement device consists of a DS2500 Near­Infrared Analyzer with pre­calibration models for PE, PP, PET and Nylon based on a large collection of real product spectra. Due to these pre­calibration models the polymer analyzer can be used immediately for the analysis of these polymers without any method development.
