Analytical Services

General isotopic and HPLC analysis are tabled but all analytical services are subject to quotation. Contact us!

Although SIIAF's main analytical field is light Stable Isotope Ratio Mass Spectrometry, we provide analytical services on other areas.

  • IRMS: C, N, H, O, S isotopes ratio analysis on different matrices
  • HPLC (UV-VIS & Fluorescence);
  • Elemental: C, N, O, S, H quantification;
  • GC-MS analysis & quantification.
 
More on sample matrices

We routinely perform bulk C,N, O, S, and H isotopic/elemental analysis on:

  • Organic material: plant, animal, litter matrices;
  • Soils and sediments;
  • Air and water (CO2; O; H).

Staff at SIIAF can also prepare special matrices for selected element isotopic analysis, e.g.:

  • Nitrates in water;
  • Sulphur in low-content matrices;
  • Cellulose;
  • Caffeine;
  • DNA;
  • Organic acids;
  • Etc.

GC-c-IRMS: Single, specific compound analysis of C isotopes through GC separation.

We can develop and implement GC-MS, HPLC-UV/Fluor. and other methods on request, according to the needs of partners and researchers.

 Analytical Quality

Isotopic Analysis at SIIAF are checked with International Atomic Energy Agency (IAEA) reference materials and in-house standards.

All analysis are checked against 2+ international reference materials on every sample batch.

On all sample batches, 1 out of 10 samples are repeated three times, to check for replication.

Linearity limits are strict and machine drift is compensated in every sample batch.
