ICAP 6500 (inductive coupled plasma spectrometry - ICP)

This appliance allows Centexbel to perform type analyses of:

  • conventional heavy metals (Pb, Cr, Ni, Sb, Cd…) in low concentrations in an acid-sweat matrix (high salt contents - for example in the framework of Oeko-Tex® standard 100)
  • various concentrations of textile-proper elements (from functional additives to micro-pollution). To this end the ICP is equipped with an optical device for radial (high concentrations) and axial (micro) measurements
  • critical elements: to this end, the ICP is equipped with a hydride modulus to determine Hg, As, Se… in a sufficiently sensitive manner
  • quantitative screening of a large range of elements in mineralised textiles in a batch solution. This includes heavy metals as well as phosphor (fire retardant), silicon (anti-slippage), titan (matting) …

Edax Orbis PC microXRF

In addition to a rapid non-destructive semi-quantitative determination of elements, from sodium to uranium, the Edax Orbis PC microXRF includes several innovative analytic techniques :

  • measurement with three optical lenses (30µm - 2mm) and several filters for e.g. RoHS (Restriction of Hazardous Substances)
  • non-destructive flaw analyses with a measure spot of 30 µm (poly-capillary lens)
  • element mapping (including bromine, chlorine, sulphur...) also on uneven surfaces
  • generation of graphical overlaps

These three techniques are extremely complementary :

  • the µXRF quickly provides semi-quantitative information on more elements than the ICP-system
  • the µXRF + ICP combination allows us to determine exactly the content on parts of the samples selected by µXRF screening
