Determination of daidzein and genistein in soybean foods by automated on-line in-tube solid-phase microextraction coupled to high-performance liquid chromatography

Determination of polycyclic aromatic hydrocarbons in food samples by automated on-line in-tube solid-phase microextraction coupled with high-performance liquid chromatography-fluorescence detection

“…We have already developed an in-tube SPME method, coupled with HPLC [32,33] and LC-MS [34][35][36], for determination of various compounds in food samples. The details of the in-tube SPME technique and its applications have been summarized in some reviews [37][38][39].…”

Sample Preparation in the Analysis of Pesticides Residue in Food by Chromatographic Techniques

“…The desorbed analytes are transported to the HPLC column for separation, and then detected with the UV or mass selective detection. Mitani et al (2003) applied an automated on-line method for the determination of the isoflavones, daidzein and genistein in soybean foods by using in-tube SPME coupled to HPLC. The detection limits obtained were 0.4 -0.5 ng/mL and the recoveries were above 97%.…”

Determination of cortisol in human saliva by automated in-tube solid-phase microextraction coupled with liquid chromatography–mass spectrometry

“…In-tube SPME allows convenient automation of the extraction process, which not only reduces the analysis time, but also provides better accuracy, precision, and sensitivity than manual off-line techniques. We have developed an in-tube SPME method for determination of various compounds, such as drugs and environmental contaminants, by coupling with HPLC [17,18], LC/MS [19,20], and LC/MS/MS [21,22]. The details of the in-tube SPME technique and its applications have also been summarized in a number of reviews [23][24][25].…”
