Development of an HS-SPME-GC method to determine the methyl anthranilate in Citrus honeys

Optimization of the Extraction of the Volatile Fraction from Honey Samples by SPME-GC-MS, Experimental Design, and Multivariate Target Functions

“…HS-SPME GC-MS is quite widespread both as a fingerprinting tool [23][24][25][26] and for identification and quantification of specific classes of compounds or single analytes [27]: it is applied to honey samples in food safety and adulteration studies (for the determination of residues of chemicals used to combat honeybee diseases or parasite infestations, as fungicides, insecticides, acaricides, and pesticides [28]) or in authenticity studies for the determination of botanical biomarkers [29][30][31].…”

“…(1) when the monovariate approach is adopted, optimization is usually accomplished on a set of selected analytes, representative of the analytes present [30,33,[35][36][37][38];…”

An accurate quantitative method for the analysis of terpenes in milk fat by headspace solid-phase microextraction coupled to gas chromatography–mass spectrometry

“…Headspace solid-phase microextraction (HS-SPME) has been widely used to extract volatile and semi-volatile compounds from different food matrices (Bertelli, Papotti, Lolli, Sabatini, & Plessi, 2008;Iglesias & Medina, 2008) including terpenes from milk and milk products (Carpino et al, 2004;Favaro, Magno, Boaretto, Bailoni, & Mantovani, 2005). HS-SPME is an attractive alternative to other conventional sampling techniques because it can be fast, sensitive, solvent-less and economical.…”

“…In this regard, different authors have proposed the actual food matrix free of target compounds as calibration matrix (Bertelli et al, 2008;López et al, 2007;Perkins, D'Arcy, Lisle & Deeth, 2005;Vichi et al, 2003), but it is not always possible to use. Pure water was used as blank matrix for the analysis of volatiles in foods with high water content such as fresh fruits, vegetables and fish (Beltran et al, 2006;Iglesias & Medina, 2008).…”

A simple dispersive liquid–liquid microextraction method for determination of Ag(I) by flame atomic absorption spectrometry

“…To sum up, a sample-preparation step was 38 generally used before instrumental analysis [34,35]. 39 For determining of trace and ultra trace of silver in several 40 samples was needed also seperation/preconcentration steps. The 41 several methods have been reported for the separation/precon-42 centration of trace amount of silver ions, such as solid-phase 43 extraction (SPE) [4,6,18-20,25], cloud point extraction (CPE) 44 [22,36], membrane filtration [17], biosorption [21], and liquid-45 liquid extraction (LLE) [37].…”
