Gas Chromatography Questions & Answers

Gas chromatography is a term used to describe the group of analytical separation techniques used to analyze volatile substances in the gas phase. In gas chromatography, the components of a sample are dissolved in a solvent and vaporized in order to separate the analytes by distributing the sample between two phases: a stationary phase and a mobile phase. The mobile phase is a chemically inert gas that serves to carry the molecules of the analyte through the heated column. Gas chromatography is one of the sole forms of chromatography that does not utilize the mobile phase for interacting with the analyte. The stationary phase is either a solid adsorbant, termed gas-solid chromatography GSC , or a liquid on an inert support, termed gas-liquid chromatography GLC. In early s, Gas chromatography GC was discovered by Mikhail Semenovich Tsvett as a separation technique to separate compounds.

The labeled ends of the strips were attached to a 6-inch glass rod by folding the ends over the rod and clipping the paper together using paper clips.

As the name implies, GC uses a carrier gas in the separation, this plays the part of the mobile phase Figure 1 1. The carrier gas transports the sample molecules through the GC system, ideally without reacting with the sample or damaging the instrument components. The sample is first introduced into the gas chromatograph GC , either with a syringe or transferred from an autosampler Figure 1 2 that may also extract the chemical components from solid or liquid sample matrices.

Сьюзан была столь же любопытна, как и ее шеф, но чутье подсказывало ей, что расшифровка алгоритма Цифровой крепости неразумна, какой бы интерес это ни представляло. В данный момент эта чертова программа надежно зашифрована и абсолютно безопасна. Но как только шифр будет взломан… - Коммандер, а не лучше ли будет… - Мне нужен ключ! - отрезал. Сьюзан должна была признать, что, услышав о Цифровой крепости, она как ученый испытала определенный интерес, желание установить, как Танкадо удалось создать такую программу. Само ее существование противоречило основным правилам криптографии. Она посмотрела на шефа.

 - Я полагаю, Хейл держит этот пароль, глубоко запрятав его в компьютере, а дома, возможно, хранит копию. Так или иначе, он попал в западню. - Тогда почему бы не вызвать службу безопасности, которая могла бы его задержать. - Пока рано, - сказал Стратмор.  - Если служба безопасности обнаружит затянувшуюся надолго работу ТРАНСТЕКСТА, перед нами возникнет целый ряд новых проблем. Я хочу уничтожить все следы Цифровой крепости до того, как мы откроем двери.
