Field-based stable isotope probing reveals the identities of benzoic acid-metabolizing microorganisms and their in situ growth in agricultural soil. We used a combination of stable isotope probing (SIP), gas chromatography-mass spectrometry-based respiration, isolation/cultivation, and quantitative PCR ....
Principle of non-additivity for sorption energy and its application in chromatographyAn earlier suggested universal equation describing the deviation from linearity of the relationship between retention parameters and increasing homologue number was applied to the calculation of retention parameters of different...
Depending on its ultimate use and area of application, the column material may be stainless steel, titanium, glass or an inert plastic such as PEEK. The column can vary in diameter from about 2mm to 5 cm and in length from 3 cm to 50 cm depending on whether it is to be used for no...
The basic principle and common process of the extension evaluation. 然后介绍了可拓评价方法的基本原理和一般步骤. 来自互联网 12. This paper introduced basic principle and development of gas chromatography - mass spectrometry ( GC - MS ). 介绍了气相色谱 - 质谱 联用分析技术的基本原理及其在纺织工业中...
Chromatography is a separation technique in which a mobile phase carrying a mixture is caused to move in contact with a selectively absorbent stationary phase. There are a number of different kinds of chromatography, which differ in the mobile and the stationary phase used. ...
g., liquid chromatography and mass spectrometry, it enables rapid and high-sensitivity profiling of complex glycan features without the need for liberation of glycans. Target samples include an extensive range of glycoconjugates involved in cells, tissues, body fluids, as well as synthetic glycans ...
As the four solutes are similar molecules, the corresponding states principle (CSP) has been tested, together with the results of several predictive equations. © 2007 American Institute of Chemical Engineers AIChE J, 2007 展开 关键词: diffusion chromatography carbon dioxide halogenated benzenes ...
AIM To discuss the relationship between the three point interaction principle in the stereoselective separation of chromatography and applying this principle to survey the infrared spectrometry of racemate. 目的 探讨色谱手性拆分三点作用原理与其用于红外光谱测定外消旋体适用性之间的关系。 2) action principl...
This is a pretty simple minded explanation. RP versus NP will "see" (meaning interact with) different portions of an oligo (or a protein). What the contaminants are relative to the desired material is may determine which type of chromatography is better for any one application. ...
Affinity chromatography is one of the most useful methods for the separation and purification of specific products. It is essentially a sample purification technique, used primarily for biological molecules such as proteins. Its major application includes: ...
