GRIM analysis at Glass Technology Services Ltd (GTS)Independent testing, research and development and consultancy facility, Glass Technology Services Ltd (GTS) has added plastics, polymers and other materials to its extensive glass fragment and foreign body analysis expertise, following a recent investment programme.

GTS Development Technologist and former Forensic Science Service Analyst, Andrew Broadhurst, said:

“We’ve invested heavily in our fragment analysis service, both for glass and non-glass samples, so we’re now able to identify the most likely source of stray glass, plastic, polymer and a wide range of other materials and – most importantly – exclude potential sources.

“In the majority of cases submitted to us, contamination by the manufacturer or processor is not the most logical explanation.”

GTS is able to issue results electronically within 24 hours of receiving the sample or, depending on the urgency, within a few hours - in many cases helping manufacturers avoid product recalls as well protect their brand reputation.

Where manufacturers, fillers, retailers or brand owners are unable to identify source materials we work directly with production sites to audit production lines - including identifying, analysing, and confirming or ruling-out potential sources of contamination to ensure that the true root cause is identified and remedial actions recommended in order to prevent recurrence.

The facility’s recent investments in fragment analysis include FTIR (Fourier Transform Infra-Red) Spectroscopy – which is able to identify plastics and polymers, such as polystyrene and polypropylene and BIO-RAD’s KnowItAll spectral database, which enables the team to provide extensive sample identifications across plastics, polymers and a wide range of other materials. Additional composition analysis is available through energy dispersive spectrometry (EDS) and wavelength-dispersive X-Ray fluorescence (XRF) .Both optical light and scanning electron microscopy (SEM) allow further vital information to be determined such as surface features, manufacturing methods and how the foreign material may have been used or damaged since its manufacture – giving clients a fuller picture of the potential origins of the source material.

GTS provides clients with a comprehensive report on a sample’s properties and potential sources and works with suppliers, manufacturers and brand owners to audit processes and investigate potential sources on-site.
