Application of Polypyrrole Coated Stainless-Steel Wire to the Headspace Solid-Phase Microextraction of Aliphatic Amines
The electrochemical coating technique was used for the preparation of a polypyrrole coating on a stainless-steel wire, and applied as a fibre for solid phase microextraction (SPME). The polypyrrole fibre was employed for analyzing four volatile aliphatic amines (ethylamine, propylamine, butylamine and pentylamine) in water by headspace SPME using gas chromatography-flame ionization detection (G...
متن کاملOptimizing Sourdough Processing for the Production of ɣ-nonalactone (Fruity Aroma) by Lactobacillus sanfranciscensis Using Headspace Solid-Phase Microextraction Method
Background and Objectives: Sourdough processing is a well-known method to improve food flavor. One of the most important lactic acid bacteria isolated from sourdoughs is Lactobacillus sanfranciscensis. Because of the bacterial ability for acidification and liberation of the volatile compound precursors, it can strongly affect dough rheology and aromatic properties. In this study, the best condi...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولOptimization of headspace solid-phase microextraction for the determination of pesticide residues in vegetables and fruits.
A headspace solid-phase microextraction method has been developed for the determination of 8 pesticides in vegetables and fruits by using gas chromatography with an electron capture detector. Two types of fibers (polyacrylate, 85 microm and polydimethylsiloxane, 100 microm) have been assayed and compared. The main factors: extraction and desorption parameters, ionic strength, and the effects of...
متن کاملSolid phase microextraction analysis of volatile constituents of heated palm olein and selected oils
Effect of heating on the development of volatile aroma constituents of palm olein and selected oils was studied. The aroma constituents of heated oils were collected using a solid-phase microextraction (SPME) headspace technique with an adsorbent of a divinylbenzene/carboxen (50/ 30μm) on polydimethylsiloxane (PDMS) fibre. The extracted volatiles were desorbed from the fibre in the injection po...
