Glass composition analysis

ISO/IEC 17025 accredited composition analysis for glass, raw materials, refractories, dusts and other inorganic materials

Our specialist knowledge in glass, combined with rapid turnaround and independent, accredited and reliable results mean we routinely support a wide client base of leading glass manufacturers and raw material suppliers in their routine checks, bench marking, material verification and diagnosing production, batch and contamination issues. See also our glass defects, stone, inclusions and contamination analysis support and analysis of heavy metals and migration for food contact materials (FCM).

Composition analysis is typically carried out by x-ray fluorescent spectrometry (XRF), but for exotic or specialist glasses, specific requirements or trace element analyses a range of additional methods can be used, including atomic absorption spectroscopy (AA), Inductively coupled plasma - optical emission spectrometry (ICP-OES) and wet chemistry. 

In-house method development enables the creation of specific calibration methods for non-standard glasses, inorganic materials and to meet specific customer requirements.

Glass composition analysis

Our specialist laboratories provide analysis of a range of standard and exotic glass compositions, including commercial (soda-lime-silicate) and borosilicate glass, for verification or benchmarking compositional variations, these include:

  • Soda-Lime-Silicate (SLS) or 'Commerical' Glass;
  • Borosilicate Glass, utilising XRF with ICP for Boron;
  • Other Glass Compositions;
  • Glass Defects, Inclusions and Contamination; Please see our glass defect and contamination analysis page for further information.

Heavy metal content analysis

Routine analysis to determine the heavy metal content of glass materials to ensure that mandatory limits are not reached. Please also see our durability and migration analysis for further information about heavy metal release and food contact material (FCM) analysis.

Water and waste composition analysis

Analysis of water and process waste to determine composition or ensure that mandatory limits of emissions are not exceeded.

Flue, fIlter and general dust composition analysis

Analysis of flue, filter and general dusts for composition. Unknown dust analysis can be carried out utilising 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

Analysis of raw materials, processing agents and cullet is provided to determine composition and purity, impurities and loss on ignition testing. For further information please see our Raw Materials and Cullet Analysis page.

Unknown material analysis

Analysis of unknown materials, including the majority of elements above Oxygen in the period table, enabling composition to be determined by X-Ray Fluorescent (XRF) Spectrometry.

Bio-material composition analysis

A range of specialist analyses for speciality bio-compatible, bio-soluble and bio-active glass-ceramic and natural minerals such as Hydroxyapatite (HA).
