“…12 Solid-phase microextraction (SPME) is one of the most popular methods for the sample preparation of VOCs, 13,14 but this method is suitable for low-volatility organic compounds because the analytes were extracted on the extraction phase based on the equilibrium between the sample matrix and the extraction phase. Solid-phase extraction (SPE) is also used for the extraction of low-volatility and relatively hydrophobic organic compounds.…”

A purge-and-trap method using a needle-type extraction device and a gas chromatography-barrier discharge ionization detector for the analysis of formic (FA) and acetic acids (AA) in aqueous samples is presented. An activated carbon-based adsorbent, Carboxen 1000, was employed as the extraction medium for the needle-type extraction device. The sampling time was 5 min for collecting headspace gas in a glass vial, including 10 mL of an aqueous sample. The detection limits for FA and AA with a headspace sampling volume of 100 mL were 3.3 and 2.0 mg L -1 , respectively. Since the proposed method was based on purge-and-trap collection, it was suitable for the determination of aqueous FA and AA in complex matrices with simple and rapid sample preparation steps. The proposed method was applied to the determination of FA and AA in fruit juice samples and FA generated by the electrochemical reduction of carbon dioxide.

“…These techniques are used to separate the constituents of liquid or gaseous mixture. In the literature the different techniques are used such as, static headspace, dynamic headspace, micro extraction [11][12][13]. In this paper the pre-concentration technique exactly dynamic headspace are used,…”

Abstract-Microorganisms are contained in all foods, some of them don't pose a risk for consumers, but many others became pathogenic, because of bad conservation or expired dates. Food will be degraded when the number of microorganisms became very large. The focus in this paper will be on the design of an electronic nose used in detecting rotten food. This nose is applied to detect bad odor diffused by rotten beef, and rotten chicken those meat have almost the same odor at rottenness which is not easily identified by human. Durations and gases emit of its rotten are determined by the pattern recognition methods PCA (Principal Components Analysis) for classification and DFA (Discriminate factorial analysis) for dating, and we will be identify between those rotten meat by DFA method. 673

“…Portable instruments and tools have been developed with several applications in illicit drugs and explosives detection, environmental monitoring, and food authentication [Perr et al, 2005;Guerra et al, 2008;Wong et al, 2013;Huang et al, 2015;Soria et al, 2015]. Some of the instruments that have been adapted for field analysis include: Gas chromatography mass spectrometry (GC-MS), ion mobility spectrometry (IMS), x-ray fluorescence spectroscopy (XRF), and laser induced breakdown spectroscopy (LIBS) [Fortes et al, 2010].…”

“…The best application for GC technique is the analysis of compounds in a mixture solution as it will provide separation followed by detection of individual compounds. Gas chromatography is the technique of choice for the analysis of many different matrixes such as ambient air, drugs, food, and explosives [Perr et al, 2005;Fan et al, 2013;Soria et al, 2015].…”
