LCGC recently spoke with Edward T. Furlong of the Methods Research and Development Program at the National Water Quality Laboratory with the U.S. Geological Survey (USGS) about his group's work on ...

This validated method is faster and simpler than other approaches, and detection limits are comparable. It is well known that the toxicity, biogeochemical behavior, and transportation of mercury in ...

Operating HPLC at higher than ambient temperatures can improve peak shapes and enable faster run times. Preheating the mobile phase is significant in high temperature liquid chromatography as the ...

Bio-based media, derived from cellulosic biomass depolymerisation or bioconversion processes, are composed of several chemicals and biochemicals. In this study, the main components of a hemicellulosic ...

Background: Ellagic acid (EA) is a natural polyphenolic compound recognized for bioactive and pharmacologic properties that is found abundantly in various plant groups, particularly eudicotyledons. In ...

Soft drinks often contain a key ingredient, such as caffeine, and one or more additives, such as benzoate or sorbate (as preservatives), and/or acesulfame K, saccharin, or aspartame (as artificial ...

This study describes a simple, fast and reproducible method using RP-HPLC-UV, in a gradient system, for quantification of reserpine in Rauvolfia sellowii stem bark. The analysis were carried out on a ...
