Nanoporous carbons (CMK-3) were prepared and have been used as a fiber coating for headspace solid phase microextraction (HS-SPME). The prepared materials were characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and N2 adsorption/desorption isotherms. The efficiency of the fiber was evaluated using a gas chromatography (GC) system for the extraction of benzene (B) and c...

Cyanide is a gaseous poison which liberated from cyanide compounds such as potassium cyanide. In spite of high toxicity, are easily accessible for industrial use, and some contamination cases into beverages have occurred. For analysis cyanide, various analytical methods colorimetric been reported. Among those, headspace-gas chromatography-nitrogen phosphorus detection (HS-GC-NPD) known its easy...

A simple and sensitive method for the simultaneous determination of ethanol, ethyl acetate, tetrahydrofuran, 2-propanol, hexane, dichloromethane and methanol in five drug substances by headspace techniques with FID detection is described. The method was validated for repeatability, linearity, limit of detection, limit of quantification and recovery according to the International Conference on H...

This paper presents, a strategy to identify persons based on measurement of human body odour from Human Sweat. To Approach this concept, the common volatile organic compounds (VOC) determined in the sweat of person of age 30 & above by using Master GC-Headspace Technique. The proposed method was capable to identify persons either with or without using deodorant irrespective of their eating habi...

This study was conducted at Horticulture Department of Cukurova University, Adana, Turkey during 2010-2011. Fresh sample of Ganoderma lucidum collected from Mersin province of Turkey was used as material. Volatile aroma compounds were performed by Headspace Gas Chromatography (HS-GC/MS). Alcohols, aldehydes, acids, phenol, L-Alanine, d-Alanine, 3Methyl, 2-Butanamine, 2-Propanamine were determin...

Background & Aim: Persian shallot (Allium hirtifolium Boiss) with common name of "Musir" is one of the endemic medicinal plants in Iran. Leaves and bulbs with antibacterial, antifungal, anticancer, anti-diabetes and anti-obesity effects are edible parts of this plant. The tissue culture is an influential method to multiply plant productions in order to meet demands of ...
