Services

The laboratory offers presently a routine determination of isotopic composition of Sr and Nd using TIMS.

The analytics of other isotope systems is possible to arrange on a base of research cooperation after an agreement with the laboratory staff (see the contacts).

Following services are available:

  • determination of the 87Sr/86Sr ratio in:

    • silicate rocks and minerals (thermic decomposition in HF and HNO3 mixture, separation on chromatographic column)
    • waters (no decomposition, separation on chromatographic column)
    • carbonate rocks (dissolution in HCl, separation on chromatographic column)
    • bones and tooth enamel (purification in CH3COOH, incineration in muffle furnace, decomposition of ash gradually in HNO3 and HCL, separation on chromatographic column)
  • determination of 143Nd/144Nd ratio in silicate rocks and minerals (thermic decomposition in the mixture of HF and HNO3, separation on chromatographic column)

Regarding a limited capacity of the workplace there is necessary all the commissions consult with the laboratory staff beforehand.
