transpec Instant Polymer Analyser Rapid Measurement of Flame Retardants and Additives
Agenda Background Introduction to transpec Features, benefits and comparison Applications Demonstration Summary Q&A
Introduction to gnosys Academic origins with industrial backbone commercial step-out following 12 years as the Polymer Research Centre always industrial application focused Expertise with materials (resins, plastics, composites) natural and synthetic polymers and resin systems composites (including micro-to-nano) functional materials and dielectrics Variety of roles ranging: from consultancy to research programs analytical services method and instrument development
Introduction to transpec transpechas been specifically designed to meet the challenging needs of the polymer, additive, compounding and masterbatchindustries. These include: an audit trail to certify materials specification linked to QA of raw materials and finished masterbatch optimised formulations for optimal properties and performance demonstrating good product stewardship while achieving materials and process cost savings
transpecprinciples-turning data into knowledge Data encompasses: Spectroscopy: Raman and wide wavelength molecular vibrations: information relating to specific compounds, functional groups and their interaction with their local environment Knowledge: Libraries of spectra / data for plastic formulations multivariate statistical analysis uses all spectral data and regresses resses it against known materials characteristics; picks out the information relating to the target parameters only -concentration, properties, processability,, performance... etc. History and legacy value gets better with use and can be re-used
Benefits The benefits of transpec include: significantsavings in time and cost of analytical support enhanced on the spot materials quality assurance and formulation control multiplecomponent analysis in the same measurement non-destructive near-line and in-line measurement improved analysis - actual rather than extracted concentrations
Comparison of techniques transpec s unique principles allow: Multiple quantitative and predictive measurements not possible using other rapid techniques Faster analysis than other quantitative destructive methods
