Gas Cylinder Setup and Use
Safe and effective gas cylinder setup and use requires the right pressure regulators, fittings, tubing, and filters as well as careful attention to procedure. This month's instalment reviews how to get the best results from laboratory gas cylinders, how pressure regulators work, and what filters should be installed in gas lines.
The Importance of Analytical Precision
Mary Ellen McNally from DuPont Crop Protection addresses the issue of precision, covering the reasons why the precision of a measurement is so important and the factors that can influence the precision of an assay.
Superficially Porous Particles: Perspectives, Practices, and Trends
An updated overview of the development of SPP technology, including benefits, limitations, and the theory behind its success
Ultra-Fast Analysis of Alkaloids and Permitted Additives in Dark Chocolate Products
A simple, rapid, and robust UHPLC method for the simultaneous determination of polyphenols, methylxanthines, sweeteners, and flavouring substances as well as some common preservatives has been developed using an automated method scouting and method optimization workflow.
Highlights of HPLC 2014
This year's symposium was held in New Orleans, Louisiana, USA. In this review, Ron Majors covers HPLC and UHPLC column and sample preparation highlights, summarizes the awards presented, and reviews the overall liquid-phase chromatographic trends.
