Specialist areas:

Our many years of expertise and state-of-the-art instruments form the basis for our high-quality results, speed and reliability. In order to live up to our quality standards, all employees take part in regular training, courses and experience exchanges. What goals can we help you to meet?


METALS:


  • ICP-MS
  • Determination of metals
  • Determination of coatings
  • Investigation of surfaces
  • Investigation of corrosion

PLASTICS:


  • Identity testing / identification
  • Determination of filler materials, e.g. glass fibres, glass beads, mineral filler materials
  • Determination of UV stabilizers, e.g. Cyasorb UV 3529, Cyasorb UV 2908
  • Determination of plasticizers, e.g. phthalates
  • Determination of decomposition products or residual monomers
  • Viscosity of plastics
  • Differential scanning calorimetry (DSC – standard procedure)
  • Thermal gravimetric analysis (TGA – standard procedure)
  • All mechanical and optical investigations (tensile tests, storage trials, ozone testing, colour testing, etc.)

OILS/GREASES:


  • Identity testing
  • Determination of additives
  • Aging criteria
  • Water content determination by Karl Fischer titration
  • Viskosität
  • Determination of particles (NAS and/or ISO)
  • Determination of PCB in oils

GASES:


  • Principal gas components; e.g.: CH4, CO2, N2, O2, CO, Ar, H2, He.
  • Trace components (e.g. siloxanes, hydrocarbons)
  • Heat value, calorific value, rel. density and Wobbe Index
  • Ʃ sulphur, Ʃ chlorine, Ʃ fluorine
  • Organosilicon compounds
  • Hydrogen sulphide H2S
  • Ammonia NH3

RESIDUAL DIRT:


  • Residual dirt testing of components to VDA 19 / ISO 16232 and in accordance with DBL 6516/6516, PV 3347, etc., and customer specifications. In addition to gravimetric evaluation, we also offer counting of particles by size classes using a Jomesa optical microscope, which allows distinction between metallic and non-metallic particles. On request, we can also perform decay measurements.
  • Identification of the largest particles by means of SEM-EDX and FT-IR microscopy
  • Gravimetric determination of organic residues containing films, e.g. to ASTM G93; on request: identification and quantification by means of FT-IR and GC-MS/GC-FID
  • Determination of residual quantities of flux in aluminium-based heat exchangers.

WATER:


  • Identification of constituents
  • Quantitative determination of (organic or inorganic) constituents
  • TOC content
  • Hydrocarbon index

MEDICAL PRODUCTS:


  • Quality assurance
  • Inspection of incoming and outgoing goods
  • Identity testing
  • Residue analysis
  • Determination of production residues (e.g. greases, oils)
  • Determination of processing agents (e.g. cyclohexane)
  • Manufacture of extracts, identification of individual substances
  • Determination of residual ethylene oxide
  • Determination of epichlorohydrin
  • Determination of UV stabilizers
  • TOC
  • CE mark testing
  • Cooperation with Notified Bodies

CONTACT ANGLE MEASUREMENT:

Contact angle measurement is a fast method for investigating the wettability of a specimen.
