D5599 Oxygenates


Alpha Omega Technology’s new R-OH Analyzer is setting the new standard for the determination of oxygenates in gasoline. The analyzer is built on a customized GC platform that incorporates a Catalytic Pyrolysis Reactor, a Hydrogenating Reactor (Methanizer), and a Flame Ionization Detector. The R-OH’s Oxygen Selective Detection System is more efficient and selective than the competition. The R-OH analyzer is fully compliant with ASTM Method D5599-17 and offers petroleum laboratory customers a robust, cost effective alternative to current offerings. The R-OH has a lower operating cost with the advantage of reduced down time with ‘fast hot-swapping’ reactor maintenance. Operators will also experience reduced break through of aromatics due to the reactor’s higher cracking capacity. The R-OH is also offered in dual analyzer configurations such as our D5599/D3606 combination analyzer.
