Determination of Limonene Oxidation Products Using SPME and GC-MS

GC–MS and GC–NPD Determination of Formaldehyde Dimethylhydrazone in Water Using SPME

Formaldehyde dimethylhydrazone (FADMH) is one of the important transformation products of residual rocket fuel 1,1-dimethylhydrazine (1,1-DMH). Thus, recent studies show that FADMH toxicity is comparable to that of undecomposed 1,1-DMH. In this study, a new method for quantification of FADMH in water based on solid phase microextraction (SPME) in combination with gas chromatography (GC) with ma...

Authenticity of raspberry flavor in food products using SPME-chiral-GC-MS.

A fast and simple method for authenticating raspberry flavors from food products was developed. The two enantiomers of the compound (E)-α-ionone from raspberry flavor were separated on a chiral gas chromatographic column. Based on the ratio of these two enantiomers, the naturalness of a raspberry flavor can be evaluated due to the fact that a natural flavor will consist almost exclusively of th...

Volatile Profiles of Honeys Using HS-SPME-GC-MS

Terpenes and terpenoids determination in present of ozone by SPME and GC-MS

Determination of Sub-ppb Level of Phthalates in Water by Auto-SPME and GC-MS Application

A solid-phase microextraction (SPME) method for the analysis of phthalates in water samples was developed on the CTC CombiPAL autosampler GC-MS platform. In this method, the sample preparation process was automated by using a CombiPAL autosampler, including the SPME fiber precondition, adsorption, and desorption, which improve the precision of the SPME method. The extraction temperature, extrac...
