Duration: 30min + 15min Q&A

The dependence of stable isotopic analyses in geochemistry and environmental measurements is steadily increasing. However, the ability to compare measurements between laboratories can be quite challenging owing to differences in measurement and calibration (standards, equipments and methods).

The key to obtaining reliable data is by designing experiments which utilize sampling methodologies that represent the environment intended for the study and meet the data-quality objectives. These samples in turn must then be calibrated against suitable reference materials containing low levels of uncertainty.

The precision and accuracy of the analytical result is directly related to the precision and accuracy of the standards used to calibrate the analytical instrument.
 

Recent studies completed by Air Liquide include:

  • The effect of vaporization on isotope fractionation as gaseous headspace is accessed when a cylinder of liquefied CO2 is depleted.
  • The effect of pressure regulators on isotope fractionation.
  • Evaluation of pressure regulators for optimal analytical effectiveness and efficiency.

Results, Conclusions and recommendations from these studies will be presented during the Webinar.
