Improve Your Linear Alpha Olefins (LAO) Impurity Analysis with Restek’s New Rxi-LAO GC Columns

As worldwide demand for polyethylene increases, so does the pressure on labs performing linear alpha olefins (LAO) impurity analysis. Restek’s Rxi-LAO columns are the first GC columns specifically applicated for the impurity analysis of LAOs. The unique selectivity provides high resolution, separating impurities from peaks of interest, such as 1-hexene and 1-octene. Herein the Rxi-LAO column was evaluated for selectivity and resolution of peaks of interest. A stringent quality control test was also developed to ensure column robustness and column-to-column reproducibility. As a result, the Rxi-LAO demonstrates high selectivity, resolution, and robustness to meet the high throughput needs of labs running the LAO analysis. Two column dimensions are available, with options for one-column and two-column configurations. The one-column method provides substantial benefits compared to two-column methods, including a simpler setup, increased instrument uptime, and higher sample throughput. Rxi-LAO columns are also fully supported by our Pro EZGC chromatogram modeler, allowing labs to optimize their LAO analysis quickly and easily.
