Process Control for the Pharmaceutical Industry

by AppliTek NV - Environmental Analysis Division     based in Nazareth, BELGIUM

Current pharmaceutical manufacturing practices would be impossible without the benefits of Process Analytical Technology (PAT) which became a framework for bottom line process understanding. The cornerstones of the PAT approach —multivariate data acquisition, process/endpoint monitoring and process analytical chemistry— are included in the AppliTek philosophy for pharmaceutical applications. Understanding and enhancing the process by our analytical solutions is our goal and, above all, your success.

Determination of Additives in Beverages using Ascentis Express Columns

by Sigma-Aldrich Co., LLC     based in Bellefonte, PENNSYLVANIA (USA)

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.
