Headspace gas chromatography HS-GC is a powerful technique for the analysis of volatile compounds. It has found broad applications for quantitative and qualitative analyses of various samples as well as for physicochemical measurements. This paper briefly reviews the basic physicochemical applications of HS-GC including vapour pressure measurements and studies of vapour-liquid equilibria in multicomponent systems. A special attention is paid to methodological aspects of these measurements. The advantages and limitations of HS-GC in this field as well as typical applications are also pointed out.

Static Headspace Gas Chromatography: Theory And Practice

The only reference to provide both current and thorough coverage of this important analytical technique Static headspace-gas chromatography HS-GC is an indispensable technique for analyzing volatile organic compounds, enabling the analyst to assay a variety of sample matrices while avoiding the costly and time-consuming preparation involved with traditional GC. Static Headspace-Gas Chromatography: Theory and Practice has long been the only reference to provide in-depth coverage of this method of analysis. The Second Edition has been thoroughly updated to reflect the most recent developments and practices, and also includes coverage of solid-phase microextraction SPME and the purge-and-trap technique. Practical examples with original data help readers to master determinations in a wide variety of areas, such as forensic, environmental, pharmaceutical, and industrial applications.

Static headspace gas chromatography is a technique used for the concentration and analysis of volatile organic compounds. Useful in the analyses of alcohols in blood and residual solvents in pharmaceutical products, as well as the industrial analyses of monomers in polymers and plastics, flavor compounds in beverages and food products, and fragrances in perfumes and cosmetics, it enables the analyst to assay a variety of sample matrices, while avoiding the time-consuming and costly preparation involved with traditional GC. This book provides the most thorough and current treatment of static HS-GC. Preis inkl. MwSt, zzgl.

When we are sick we rely heavily on chemistry to quickly restore our health and make us fully operational again. Pharmaceutical manufacturers put a high priority on controlling the quality and safety of their products. A key part of this is rigorous chemical analysis, in both qualitative and quantitative terms, to monitor for potential impurities arising from possible variances in the manufacturing process — such as raw materials or from contact materials in packaging, for example. Due to high levels of regulatory control, it is not surprising that the control of pharmaceutical impurities in a compliant manner is currently a critical and challenging issue to the pharmaceutical industry. Several analytical methods are typically used for impurities identification and quantitation, but considering organic volatile impurities like residual solvents or volatile extractable and leachable organic compounds, gas chromatography is the technique of choice. There is not a much easier method, in terms of sample preparation, than taking your solid sample, putting it into a sealed 10 mL or 20 mL vial with a few mL of water and dissolving it. This is the benefit of the Headspace Sampling technique which relies on the equilibrium of volatile compound concentration established between the solid phase sample and the gas phase above it headspace into a sealed vial.

Static Headspace-Gas Chromatography

And I shall never forgive myself for being so stupid as not to see it. I stared at the blaze in the fireplace. The statement was so unreal, the import so incredible, that at first I had not even a sensation of shock. All I could think of was a dim library with the rain splashing down the windows, in a garden of the Faubourg Saint-Germain. And there I saw an old stocky man, with a heavy moustache and a bald head, standing rigid in his fine broadcloth, his hard eyes fixed on us.

 - Супружеская пара без секретов - это очень скучно. Сьюзан застенчиво улыбнулась.

Headspace—Gas Chromatography

 - Простите, сэр… Человек не шевельнулся. Беккер предпринял очередную попытку: - Сэр. Старик заворочался. - Qu'est-ce… quelle heureest… - Он медленно открыл глаза, посмотрел на Беккера и скорчил гримасу, недовольный тем, что его потревожили.

Как они смогут ему противостоять. Эти аргументы она слышала уже много. Гипотетическое будущее правительство служило главным аргументом Фонда электронных границ. - Стратмора надо остановить! - кричал Хейл.  - Клянусь, я сделаю. Этим я и занимался сегодня весь день - считывал тексты с его терминала, чтобы быть наготове, когда он сделает первый шаг, чтобы вмонтировать этот чертов черный ход.

Водитель кивнул, с любопытством разглядывая пассажира в зеркало заднего вида. - Колдун, - пробурчал он себе под нос.  - Ну и публика собирается там каждый вечер. ГЛАВА 53 Токуген Нуматака лежал на массажном столе в своем кабинете на верхнем этаже. Личная массажистка разминала затекшие мышцы его шеи. Погрузив ладони в складки жира на плечах шефа, она медленно двигалась вниз, к полотенцу, прикрывавшему нижнюю часть его спины. Ее руки спускались все ниже, забираясь под полотенце.

 Халохот был профессионалом высокого уровня, сэр. Мы были свидетелями убийства, поскольку находились всего в пятидесяти метрах от места. Все данные говорят, что Танкадо ни о чем таком даже не подозревал. - Данные? - спросил Бринкерхофф.  - Какие такие данные. Танкадо отдал кольцо.

Это ловушка. Энсей Танкадо всучил вам Северную Дакоту, так как он знал, что вы начнете искать. Что бы ни содержалось в его посланиях, он хотел, чтобы вы их нашли, - это ложный след. - У тебя хорошее чутье, - парировал Стратмор, - но есть кое-что. Я ничего не нашел на Северную Дакоту, поэтому изменил направление поиска. В записи, которую я обнаружил, фигурирует другое имя - N DAKOTA. Сьюзан покачала головой.

Беккер изобразил улыбку. - Я должен идти. Он извинился перед немцем за вторжение, в ответ на что тот скромно улыбнулся.

 - Стремительная. Все люди на подиуме потянулись к терминалу в одно и то же мгновение, образовав единое сплетение вытянутых рук. Но Сьюзан, опередив всех, прикоснулась к клавиатуре и нажала цифру 3.

Стеклянная панель обдала его дождем осколков.
