Commercialization of technologies to produce faster temperature ramps in GC have been some of the few GC advances in recent decades. This article will take a look at the utility and ultimate areas of practical application for these technologies.
Is the analytical result you are reporting valid? Maybe the ones from yesterday or last week were, but will the ones from today also be? Will the results from your tray of 70 samples have to be thrown out and the analyses be run again? This month...
In this article we discuss the merits and deficiencies of sandwich injection techniques.
In this article we discuss issues related to inlet and liner activity.
In this article we discuss the calibration technique of standard addition.
This technical article covers the internal standard method of GC calibration.
This technical article discusses general approaches to GC response calibration and focuses on the simplest; external calibration.
In this article we continue the previous discussion of ferrules used in gas chromatography.
In this article we cover the first part of an important and often neglected topic: ferrules.
Under discussion is one of the newer approaches to capillary column backflush: the uncoated pre-column configuration.
Continuing our discussion of the three configurations of capillary column backflush, we cover the coated pre-column configuration.
We continue the previous article's backflush discussion with a description of the most common form of backflush: post-column backflush.
