The volatile profile of fruits determined by gas chromatography and mass spectroscopy is complex, including many alcohols, aldehydes and esters. |
The extracts obtained were prefiltered through glass wool and sodium sulfate anhydride and filtered by column chromatography. |
Traditional toxicology screens that employ thin-layer chromatography can detect MDMA metabolites in the urine. |
Final separation was achieved by fast protein liquid chromatography, followed by dialysis and lyophilization, resulting in a white powder. |
Fatty acid methyl esters were analyzed by gas chromatography as described above. |
The platinated oligonucleotides were repurified by ion-exchange fast protein liquid chromatography. |
