Determination of methylisoborneol in channel catfish pond water by solid phase extraction followed by gas chromatography-mass spectrometry

Simultaneous determination of eight common odors in natural water body using automatic purge and trap coupled to gas chromatography with mass spectrometry

“…Although this method greatly improves the limits of detection and is less time-consuming compared to CLSA, analysis of low-boilingpoint compounds, such as sulfides is difficult [29,30]. Solid-phase extraction (SPE), as a powerful extraction technique for analysis of water odors, is time-consuming and unsuitable for the analysis of low-boiling-point odors [31][32][33][34]. As technology advances, solid-phase microextraction (SPME) and headspace solid phase microextraction (HS-SPME) have become the most popular extraction techniques in treating and neutralizing a large number of water 0021-9673/$ -see front matter © 2011 Elsevier B.V.

Simultaneous analysis of five taste and odor compounds in surface water using solid-phase extraction and gas chromatography-mass spectrometry

“…Conte et al [9] determined that 2 mL eluting solvent was enough for 2-MIB elution. The optimum volume can be obtained using a modified method described in Ref.…”

“…The optimum volume can be obtained using a modified method described in Ref. [9]: load a C18 column with a mixture of five compounds(10 μg$mL -1 , 1mL) and repeatedly rinse the column using l mL portions of methanol, and it was found out that after a single rinse, 88% (average) of the five compounds had been eluted; after two rinses, over 95% (average) of the five compounds had been eluted; and after three rinses, all the compounds had been eluted. Thus, 3 mL methanol is sufficient for all the five compounds.…”

“…Traditional analytical methods for 2-MIB and GSM include closed-loop stripping [7], liquid-liquid extraction [8], solid-phase extraction [9], steam distillation [10,11], and membrane-based extraction [12]. Purge and trap technique (P&T) has also been reported to be applied in concentrating GSM and 2-MIB [13].…”

Development of polypropylene glycol coated hollow fiber membranes as passive sampler for field equilibrium sampling of odorous compounds in environmental waters

“…[9][10][11][12][13][14][15] Because of the extremely high sensitivity required for detection of these compounds, it is essential to have enrichment or extraction steps before GC-MS analysis. A variety of enrichment/extraction techniques including closed-loop stripping analysis, 12,16 hollow fiber stripping analysis, 11 liquid-liquid extraction (LLE), 14,17,18 solid-phase extraction (SPE), 10,19,20 purge and trap, 8,9 headspace liquid-phase microextraction, 21,22 stir bar sorptive extraction, [23][24][25] and solidphase microextraction (SPME) 8,13,15,[26][27][28][29][30][31] have been applied to preconcentrate trace amounts of MIB and GSM in water. While most of these sample pretreatment procedures provide detection limits of $1 ng L À1 for MIB and GSM, lower detection limits were obtained by using closed-loop stripping (0.01-0.03 ng L À1 ), 12 stir bar sorptive extraction (0.025-0.041 ng L…”
