Perfluorooctanoic acid (PFOA) is a persistent and recalcitrant organic contaminant of high EPA priority. Adsorption is considered an effective technique for PFOA removal and more efficient PFOA sorbents are still of interest…
Since its development in 2006, dispersive liquid-liquid microextraction (DLLME) has become one of the most widely used sample preparation techniques. We have tested several cyanoalkyl silicone GC stationary phases as an extraction solvent for DLLME…
Gas chromatography (GC) with flame ionization detection (FID) is still an important relatively inexpensive problem solving analytical method despite the maturity of this technique…
We have found dimethyl carbonate (DMC) to be a versatile mobile phase modifier for three different modes of liquid chromatography (LC). DMC is a moderately polar modifier with a lower UV-cutoff than an ester for normal-phase LC…
