Elemental and compositional analyses

We provide analytical services for most sample matrices and nearly all the elements in nature with a variety of instruments and methods, including HR-ICP-MS analysis, elemental analyzers, gas and liquid chromatographic methods and ion chromatography.

Gas phase:

  • Full gas compositional quantification of He, H2, Ar, O2, N2, CH4, CO, CO2, H2S and all hydrocarbons from nC2-nC6
  • Acidic gas analysis HF, HCl, HBr, HNO3
  • Gas composition analysis of H2S, CS2, COS, Methyl Mercaptane
  • BTEX, Composition of Benzene, Toluene, Ethylbenzene, Xylene from Tenax TA thermal desorption tubes.
  • Ammonia gas in methane, air or hydrogen
  • Ultratrace gas impurity analysis with carbon molecular sieves and sub ambient temperatures together with PDHID: Gas composition of nC1-nC5.
  • Gas composition analysis of Ar, O2, N2, CO at sub ambient temperatures with complete baseline separation of oxygen and argon.
  • Chlorine gas in hydrogen

 

Liquid phase:

  • Chloride, iodine, bromine, fluorine and other anions in water
  • Strontium and sulfur together with the stable isotopes δ87Sr and δ34S in water matrix
  • Multi-element analysis in a water matrix of different origins (e.g. waste-, formation-, ground- and surface water)

 

Solid phase:

  • Bulk and compound-specific carbon, nitrogen, hydrogen, sulfur (CHNS) – can be combined with the stable isotopes δ34S, δ13C and δ15N (commonly biota but also possible in other matrices – ask us!)
  • Microwave digestion and ICP-MS analysis of solids for metals and other “heavy” elements (e.g. contaminants in soil, verification of industrial processes)
