Ion Chromatography in Environmental Analysis

Development and Validation of an Ion Chromatography Method for Quantification of Ammonium Ions in STEALTH® Liposomes

Ammonium sulfate is one of the subsidiary components in the stealth liposome structure. The ratio of ammonium ion bound to liposome sphere to ammonium ions outside the liposome plays an important role in drug delivery formulation; accordingly, in order to quantify the ammonium ion in the liposome structure, a rapid and sensitive method was validated using a conductivity detector. Through this m...

The Role of Ion Chromatography in Food Safety Laboratories

Polar ionic pesticides, such as glyphosate and chlorate, are often extracted using the Quick Polar Pesticides Extraction (QuPPe) method. This method, which uses acidified methanol, does not incorporate solvent partitioning or cleanup steps. The extracts can contain high amounts of co-extracted matrix compounds and thus difficult to analyze. Individual extracts must be analyzed multiple times us...

Application of gas chromatography in food analysis

Gas chromatography (GC) is used widely in applications involving food analysis. Typical applications pertain to the quantitative and/or qualitative analysis of food composition, natural products, food additives, flavor and aroma components, a variety of transformation products, and contaminants, such as pesticides, fumigants, environmental pollutants, natural toxins, veterinary drugs, and packa...

Gas chromatography-olfactometry in food flavour analysis.

The application of gas chromatography-olfactometry (GC-O) in food flavour analysis represents to be a valuable technique to characterise odour-active, as well as character impact compounds, responsible for the characterizing odour of a food sample. The present article briefly reviews the use of GC-O in the flavour investigation of dairy products (milk and cheese), coffee, meat and fruits. Parti...
