Determination of BTEX Compounds in Water by Solid-Phase Microextraction and Raman Spectroscopy

Monitoring of Polycyclic Aromatic Hydrocarbons in Water Using Headspace Solid-Phase Microextraction and Capillary Gas Chromatography

“…In addition, SPME has been successfully used as a device for sampling volatile organic compounds from biological samples and foodstuffs in chromatographic analysis (28 -33). Besides its chromatographic utility, SPME has been used for sampling in Raman spectroscopy (34), mass spectroscopy (18,35), and ultraviolet adsorption spectroscopy (36,37). SPME has also been used for the determination of PAHs in water and soil samples (17, 25, 38 -41).…”

Analysis of n-Alkanes at Sub Microgram per Liter Level after Direct Solid Phase Microextraction from Aqueous Samples

“…The most widespread seems to be analysis of volatile and semivolatile compounds in water. Examples in this area include determination of substituted benzene compounds, 2,3 volatile organic compounds, [4][5][6] polycyclic aromatic hydrocarbons and polychlorinated biphenyls, 7 pesticides, [8][9][10][11][12][13] phenols, 14,15 fatty acids, 16 as well as lead and tetraethyl lead. 17 In direct extraction mode (as one of three SPME modes), the coated fiber is inserted into the sample and the analytes are transported directly from the sample matrix to the extracting phase.…”

Analysis of Residual Solvents in Ampicillin Powder by Headspace Spectrophotometric Method

“…[2][3][4][5][6][7][8][9][10] Not only is this very time-consuming but losses of volatiles during sample collection can be substantial. [11][12][13][14] Also, other analytical methods such as differential optical absorption spectroscopy, 15,16 Raman spectroscopy 17 and ion mobility spectrometer using photoionization 18 have been used for analysis of the volatile compounds.…”
