Foss A/S - Rapid Resin Analyzer
| Year of introduction
Spectrometer ( Molec. ): NIR
The FOSS RapidResin™ Analyzer identifies look-a-like polymer resin materials and spots contaminants. The RapidResin Analyzer works with most types of thermoplastic resin pellets. A pour-in design accepts a large, representative sample of pellets and ensures easy filling and cleaning.
The RapidResin Analyzer can be used to determine blend ratios and to identify additives, measure melt index and density. The RapidResin Analyzer replaces several types of standard wet laboratory tests for the quantitative analysis of additives, moisture in polymers, determination of copolymer ratios, and residual monomer measurement and best of all... It requires no solvents or sample preparation of any kind.
The RapidResin Analyzer is the fastest method available for quality control testing of polymer resins. It is ruggedly designed for at-line operation as well as laboratory use, and can determine blend ratios, additive levels, and batch-to-batch consistency in just one minute.
Use it to identify resins before processing, to check for contaminants, and to test lot-to-lot consistency. Used routinely, the RapidResin can prevent costly reprocessing and waste.
The pour-through design gives convenient rapid analysis of any bulk resin sample (2 kg) in pellet or flake form. Bulk analysis is far more reliable than standard industry methods which rely on single-pellet films or lengthy solvent extractions.
Operation is based on near-infrared (NIR) technology, which is completely non-destructive. The RapidResin returns each bulk sample unharmed for further testing, if desired.
The user calibrates the RapidResin, and the user’s current primary methods serve as the reference method. It can be calibrated to measure virtually any polymer parameters of interest:
After a range of calibrations have been developed on the RapidResin Analyzer, very useful Identification and Qualification functions can be implemented for streamlining inspection and QC procedures.
