Extraction of volatile compounds from complex liquid matrixes is a critical step in volatile compound anal. workflows. Recently, green chem. principles are increasingly implemented in extraction processes. Some of the available approaches are solvent-free but still require concentration or trapping of analytes. Here, we propose effervescent tablet-induced extraction (ETIE) as a method of transferring volatile/semivolatile compounds from liquid matrixes to the gas phase for anal. This technique relies on the release of carbon dioxide produced in situ during a neutralization reaction, which occurs when a tablet is inserted into an aqueous sample matrix. In this process, many bubbles of carbon dioxide are instantly formed in the sample matrix. The bubbles rapidly extract and liberate volatile compounds from the sample. The gaseous effluent is then immediately transferred to a detector (atm. pressure chem. ionization mass spectrometry (MS) or gas chromatog. (GC) hyphenated with MS). ETIE-GC-MS can be used for anal. of volatile compounds present in real samples. The method was validated for anal. of selected Et esters present in a yogurt drink. The calibration data set was linear over a range from 5 × 10-7 to 1 × 10-5 M. The limits of detection ranged from 1.51 × 10-7 to 6.82 × 10-7 M, while the recoveries ranged from 71 to 118%. Inter- and intraday precision of selected Et esters in aqueous solution was satisfactory (relative standard deviation, 3.6-18.3%). Furthermore, it is shown that ETIE improves the performance of headspace solid-phase microextraction while eliminating the need for heating and shaking samples.
