SELEX

Italian Patent N 102017000147374

Non destructive fast analysis of materials based on the innovative soft x-rays technique
SELEX.
It combines X-ray Transmission, Absorption, Scattering and Fluorescence

SELEX is a spectroscopic X-ray diagnostics developed for black plastics from WEEE and automotive.

Main characteristics

  • No need for sample preparation
  • Solids, grains and liquids
  • Fully automatic with user friendly output
  • Fast (< 1 minute)
  • Flexible design of the instrument
  • Preliminary tests and feasibility studies on demand
  • CE certification

Black plastics represent an important and growing fraction of WEEE and automotive waste. Black plastics cannot be automatically identified and recycled.Therefore, they have to be stored and/or burned with great danger of polluting the environment.

No automatic technique is available for black plastics recognition and discrimination.

Spectroscopic techniques such as NIR and RAMAN, that are used effectively for coloured plastics do not work with black plastics.

SELEX is an innovative technique utilising soft X-rays to discriminate black plastics. With this technique polymers, fillers and additives are identified and quantified in any type of transparent/coloured/black plastics, without previous treatment of the sample.

The SELEX technique has been implemented in a portable device for random and quality tests. It is now available for purchase.

APPLICATIONS

PLASTICS AND POLYMERS

  • Black plastics
  • Identification of polymer, additives and filler
  • Solid and granulate 

LEATHER AND FABRICS

  • Measurement of absolute concentration of light (Al, Ti, Ni, Fe, Cr, Zn, Co..) and heavy metals  (As, Zr, Cd, Pb, Hg..) and other elements (Si, P, Cl, Ca..) with high accuracy (up to 1 ppm)/li>
  • Traceability (manufacturer, production lot)

MULTILAYER MATERIALS AND SUBSTRATES

  • Recognition of the combination of different materials (layers) in multistrate materials (semiconductors)

METALLURGY

  • Recognition and separation of different metals
  • Composition, purity and classification of metals and alloys

CONTAMINATION and COUNTERFEIT

  • Detection of dangerous or sensitive elements (Br, Pb, Cd, As, Hg, Bi..) in any material
  • Compliance analysis

QUALITY CONTROL IN MANUFACTURING

  • Analysis and composition of input raw material
  • Quality control of the final product

Black and coloured certified plastic samples and waste from WEEE (Electric and Electronic Equipment)

Example of polymer with filler

In an individual measurement of a few seconds, on a given untreated sample, SELEX quantifies the content of:
Polymers: PP, PE, PS, ABS, PC-ABS, PA, PC, PMMA, POM, PBT, PVC
Fillers: Calcium carbonate, talc, barium sulfate…(with precision of 1 % or even better)
Reinforcers: fiber glass
Fluidificants: Zinc or Calcium stearate
Flame ratardants: phosphates or Bromin compounds
Mineral colorants: Ti oxide, Fe oxides, compounds with Cr, Ni, Cd…
Pollutants or critical elements: Lead, Bormine, Antimony….

Traceability

SELEX device can be applied to recognize different kinds of leather (even black), identify manufacturer and distinguish among different batches of the same manufacturer. 

Detection of metals and elements

SELEX is able to measure the absolute concentration (ppm) of: 

Metals (Al, Ni, Ti, Cr, Fe, Cu, Zn, Co…)

Heavy Metals (Pb, Hg, Zr, Cd…)

Light elements (Sl, P, S, Cl, Ca…)

Recognize metal free leathers

Metal free leather

SELEX applications: metallurgy

Composition of metals and alloys and impurities for quality control

Aluminum

Cadmium

SELEX applications: contamination and counterfeit

Detection of contaminants

Traces of minerals and metals in food (e.g., Zinc in barley). In the example, Bromine can be detected in salad (residue from pesticide), Strontium in prawn.

Materials identification to prevent counterfeit
