Reports on Chromatography Findings from INIA Provide New Insights

May 23, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Science are discussed in a new report. According to news reporting originating from Madrid, Spain, by NewsRx correspondents, research stated, "In this work, an analytical method was developed for the determination of pharmaceutical drugs in biosolids. Samples were extracted with an acidic mixture of water and acetone (1:2, v/v) and supported liquid extraction was used for the clean-up of extracts, eluting with ethyl acetate:methanol (90:10, v/v)."

Our news editors obtained a quote from the research from INIA, "The compounds were determined by gas chromatography-tandem mass spectrometry using matrix-match calibration after silylation to form their t-butyldimethylsilyl derivatives. This method presents various advantages, such as a fairly simple operation for the analysis of complex matrices, the use of inexpensive glassware and low solvent volumes. Satisfactory mean recoveries were obtained with the developed method ranging from 70 to 120% with relative standard deviations (RSDs) Madrid and Catalonia (Spain). Eleven of the sixteen target compounds were detected in the studied samples, at levels up to 1.1 mu g g(-1) (salicylic acid)."

According to the news editors, the research concluded: "Ibuprofen, caffeine, paracetamol and fenofibrate were detected in all of the samples analyzed."
