Analysis of the Volatile Components of Five Turkish Rhododendron Species by Headspace Solid-Phase Microextraction and GC-MS (HS-SPME-GC-MS)

Analysis of the volatile components of five Turkish Rhododendron species by headspace solid-phase microextraction and GC-MS (HS-SPME-GC-MS).

Volatile constituents of various solvent extracts (n-hexane, CH2Cl2, H2O) of 15 different organs (leaves, flowers, fruits) of five Rhododendron species (Ericaceae) growing in Turkey were trapped with headspace solid-phase microextraction (HS-SPME) technique and analyzed by GC-MS. A total of 200 compounds were detected and identified from organic extracts, while the water extracts contained only...

Method development by GC-ECD and HS-SPME-GC-MS for beer volatile analysis.

Two methods for the extraction, identification and quantification of the highest occurrence and lowest perception threshold off-flavours in fifteen different samples of Brazilian Pilsner beers were developed. For this purpose, headspace solid phase microextraction in combination with a gas chromatography coupled to a mass spectrometric detection (HS-SPME-GC-MS) as well as headspace extraction i...

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

Identification of Honey Volatile Components by Solid Phase Microextraction (spme) and Gas Chromatography/mass Spectrometry (gc/ms)

Volatile compounds in honey samples of different botanical origins were investigated. Solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC/MS) revealed a total of 86 compounds in the headspace of 4 types of honey – multifloral, heather, buckwheat and lime-honeydew. The chemical composition of the headspace was very diverse, owing to the presence of compounds from diff...

Analysis of Five Earthy-Musty Odorants in Environmental Water by HS-SPME/GC-MS

The pressing issue of earthy and musty odor compounds in natural waters, which can affect the organoleptic properties of drinking water, makes it a public health concern. A simple and sensitive method for simultaneous analysis of five odorants in environmental water was developed by headspace solid-phase microextraction (HS-SPME) coupled to chromatography-mass spectrometry (GC-MS), including ge...
