Scientists have developed a new method to analyze associated gas components using a multidimensional gas chromatography system. This system combines packed and capillary columns with specific detectors to separate and detect different types of gases in one injection. The new approach is faster, more accurate, and efficient compared to previous methods, which were complicated and prone to errors. Lighter components like ethane and methane are separated and detected by one column, while heavier components like propane are separated and detected by another column. This method simplifies the process and improves the precision of analyzing associated gas samples.
