Abstract SoI-geI capiIIary coIumn in gas chromatography is a new type of coIumn. Compared with the coIumn that is made using static coating and free radicaI cross-Iinking,this new type coIumn has the conspicuous advantage of higher stabiIity at high temperatures and in soIvents,as weII ...
In a column for separating gases or vapours by the chromatographic method, the partitioning agent is coated on the inner wall of the column. Ethylene glycol may be used as the coating, when preferably the inside of the tube is roughened, or the partition agent may be mixed with a dendrifor...
- 《Journal of Liquid Chromatography》 被引量: 65发表: 1984年 Effect of dead volume on efficiency of a gas chromatographic system Our results, while in general agreement with the theoretical results of others, indicate that in gas chromatography, pre-column dead volume can be a much more impor...
Gas chromatography column Introduction: BK-GC900 gas chromatograph is a popular, high-performance, multi-functional series of chromatographic instruments. FID, TCD and FPD detectors can be combined as needed to meet the needs of ordinary laboratories, daily production, routine detection and trace ...
An overview of the existing methods for minimization of the analysis time in gas chromatography (GC) is presented and a new system for fast temperature programming and very fast cooling down is evaluated. In this study, a system of coaxial tubes, a heating/cooling module (HC-M), was develop...
Gas chromatography column; formed in a conductive or semiconductive column material; organic layer formed by the reduction of an onium salt on the column bonded to inner wall of the column material surface; stationary phase material bonded to organic layer; uniform thickness ...
Our technical department is often involved in helping clients with “gas chromatography (GC) column autopsies.” Over the years, we have come to know the most common ways that you can effectively dispatch a column. However, like anything related to health, there are cures and preventative measur...
The determination of methandienone (1) (17α-methyl-17β-hydroxyandrosta-1,4-dien-3-one) in human urine by gas chromatography and capillary column gas chromatograpy—mass spectrometry has been studied. After oral administration to man two major metabolites were detected, the structures of which...
This chapter discusses the fused silica glass capillary column for gas chromatography. Approximately five years after the announcement of the use of flexible fused silica glass tubing for capillary column gas chromatography, evidence developed from a group of laboratories in Europe and in the United St...
