Air Liquide in the value chain

Petroleum analysis

Air Liquide supplies industrial gases, pure specialty gases, and Scott™ brand liquid and gas calibration mixtures to enhance reliability and provide precise calibration for accurate exploration and production development planning. Our patented cylinder treatment options ensure consistent and reliable accuracy and stability of your specialty gas, even for very low level sulfur components. These products are perfect for use in petroleum geochemistry, compositional analysis and sulfur compounds speciation.

Air Liquide also supplies Scott brand gaseous stable isotope mixtures to enhance the reliability of petroleum geochemistry analysis with precise calibration. Isotopic analysis maximizes the information obtained from each well, reservoir or field and helps you to carry out accurate exploration and production development planning. Our highly accurate calibration standards have a unique product range of multi-component gas calibration mixtures up to C5, with specific δ13C ratios available off-the-shelf. Our gaseous stable isotope pure gases and gas mixtures provide precise calibration to enhance the reliability of analysis when it is critical to measuring δ values accurately. Available in Mini-Mix Transportable cylinders, stable isotopic mixtures are dual function – they can serve as calibration gases for quantitative analysis of gas samples and/or as secondary or quality assurance standards for instrumental analysis of stable isotope samples.
