Analytical Services
for Elemental and Stable Isotope Analysis


In addition to manufacturing EA consumables, OEA Labs is also a recognised and respected commercial laboratory specialising in elemental and stable isotope analysis.  Our laboratories provide prompt and accurate analytical data for universities, research organisations and companies worldwide.


Stable Isotope Analysis ( SIA )
With two continuous-flow isotope ratio mass spectrometers both interfaced with configured elemental analysers, OEA Labs routinely analyse the stable isotope ratios of carbon (13C/12C), nitrogen (15N/14N), oxygen(18O/16O) and sulfur (34S/32S) on solid or liquid samples.


Elemental Analysis 
Our three dedicated elemental analysers routinely determine carbon, hydrogen, nitrogen, oxygen and sulfur in a wide range of organic and inorganic materials. Skilled technicians analyse these elements from high percentages down to less than 0.01% on solid, liquid, or even gaseous samples. We also determine total organic carbon (TOC), total inorganic carbon (TIC), and protein.

Elemental analysis (also known as elemental microanalysis) is a reliable and cost-effective technique used to assess the purity and chemical composition of research compounds or to provide information of the composition of materials.

Other Techniques
Hydro-combustion, acid digestion and oxygen flask techniques are employed to prepare samples for analysis by Ion Chromatography (IC), UV/Vis spectroscopy, titration and ion specific techniques to determine total fluorine, chlorine, bromine, iodine and phosphorus in both organic and inorganic samples. Our technicians quantify these elements from percentage levels down to parts per million. We also analyse numerous anions such as nitrite, nitrate, sulfite, sulfate, phosphite, and phosphate as well asundertake other non-routine analysis.
