Polysense Innovations has just published a new article on ACS Omega in collaboration with Saudi Aramco Company reporting on the performance of a compact and portable QEPAS system able to measure concentrations of methane (C1), ethane (C2), and propane (C3) in gas phase within the percentage range that is typically encountered in natural gas samples from oil and gas fields.

 

An iterative analysis based on multilinear regression of QEPAS spectra was developed to filter out the influence of gas matrix variation from multiple hydrocarbon components. The advance in simultaneous measuring hydrocarbon gases and expanded linearity range of QEPAS opens a way to use the advanced sensing technology for in situ and real-time gas detection and chemical analysis in the oil industry.
