  • Gas infusion technology solutions for the water treatment industry

    Every municipality in the developed world has some form of water and wastewater treatment system. This varies from simple outfalls direct to the ocean to very sophisticated activated sludge plants with multiple unit processes dedicated to converting human waste, industrial effluents and storm runoff into clean water discharges and solids acceptable for some form of reuse. inVentures using its gas inFusion technology, has developed the gPRO system for the prevention and remediation of major algae blooms that negatively affect the water quality for millions of people. The company is currently working with several major water authorities on algae prevention programs by efficiently oxygenating specific regions of the water storage areas. Target Oxygenation prevents the build up of algal masses. Algal masses often require expensive treatment remedies and cause major taste and odor issues within drinking water supplies.

    Determination of Additives in Beverages using Ascentis Express Columns

    Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. Dilution followed by direct injection into an HPLC is typically suitable. In this article we present two beverage applications using Ascentis Express HPLC columns. Ascentis Express columns offer faster HPLC on any system. One benefit is their ability to produce the resolution, efficiency, and speed on conventional HPLC systems that is associated with the use of sub-2 micron columns on a UHPLC system, without generating high backpressure. Column chemistries (RP-Amide and HILIC) were selected for this article based on their enhanced performance with polar compounds in comparison to C18.
