Potassium permanganate activated alumina is an outstanding choice for air purification systems, offering twice the adsorption capacity of similar products while also having strong oxidizing and degassing capabilities to rid airways of potentially dangerous gases.
Process Description: The procedure involves mixing partially calcined activated alumina with an aqueous solution of potassium permanganate and drying the resultant granules; these are then cured to prevent further rehydration.
GC PPA12
GC PPA12 is a spherical activated alumina impregnated with 12% potassium permanganate for use in applications where regular activated carbon may not be suitable, including the adsorption and oxidation of lower molecular weight compounds such as those polar in nature or having lower molecular weight compounds. Furthermore, its higher KMnO4 concentration compares favorably with similar granular products, giving this solution longer service life.
Gas chromatography (GC) isolates volatile compounds by employing narrow-bore capillary columns with high surface area-to-volume ratio. Its chromatograms provide useful ways of analyzing and quantifying complex mixtures; each peak in a chromatogram corresponds to an amount of compounds present in the sample.
ProGuard 200 is a spherical alumina impregnated with potassium permanganate designed to absorb and neutralize harmful hydrogen sulfide gasses produced in HVAC systems at refineries, steel mills, wastewater treatment plants, hospitals, schools, labs commercial buildings museums etc. by adsorbing or chemisorbing them safely back into byproducts; furthermore it boasts longer service life than standard activated alumina products due to containing more potassium permanganate content.
GC PPA20
GC technology uses narrow-bore capillary columns to rapidly separate volatile chemicals into their individual components. Once separated, these compounds are detected using flame photometers or electron capture detectors (ECD), with each peak on a chromatogram showing the concentration of that particular compound. As it operates under controlled conditions and high surface-area-to-volume ratio columns are utilized, GC provides reliable quantitative results.
Recent advances in gas chromatography technology include comprehensive two-dimensional GC (2D-GC). When applied to samples such as diesel fuel where alkanes typically dominate one dimensional (1D) separation, adding a second column increases peak capacity for dimension 3 (7,7) separation.
