Composition analysis is typically carried out by x-ray fluorescence spectrometry (XRF). However, for exotic or specialist glasses, or other specific requirements, we can use trace element analysis or various additional methods – such as atomic absorption spectroscopy, inductively coupled plasma, optical emission spectrometry and wet chemistry.
Our specialist knowledge in glass, combined with independent, accredited and reliable results, enables us to support a wide client base of leading glass manufacturers and raw material suppliers. We
- provide benchmarking
- verify materials
- diagnose production, batch and contamination issues
Our in-house method development allows us to create specific calibration techniques for non-standard glasses and inorganic materials, and to meet your specific requirements.
This service is applicable to glass, raw materials, refractories, dust and other inorganic materials. We can report on a wide range of both standard and specialist glass compositions including
- borosilicate glass, utilising an XRF with ICP for boron
- other glass compositions, such as synthetic bone material
Heavy metal content analysis
We undertake routine analysis to determine the heavy metal content of glass materials to ensure that mandatory limits are not exceeded. Visit our durability and migration analysis service page for further information about heavy metal release and food contact material analysis.
Water and waste composition analysis
We analyse water and process waste to determine the composition, or to ensure that mandatory emissions limits are not exceeded.
Flue, filter and general dust composition analysis
We analyse flue, filter and general dusts for composition. Unknown dust analysis can be carried out using our instruments’ in-built synthetic calibrations, enabling the equipment to scan for almost all elements above oxygen on the periodic table.
Raw materials and cullet analysis
We analyse raw materials, processing agents and cullet to determine the composition and purity, impurities and loss on ignition.
Unknown material analysis
We analyse unknown materials, including most elements above oxygen in the periodic table – enabling composition to be determined by x-ray fluorescence spectrometry.
Bio-material composition analysis
We provide a range of specialist analyses for specialty bio-compatible, bio-soluble and bio-active glass-ceramic, and natural minerals such as hydroxyapatite.
Glass composition analysis leadership and expertise
Our experts in glass analysis can advise on the best and most appropriate testing methods. Unlike other providers who may send a generic report, we answer your key questions and interpret test results to your specific situation and requirements.
