In this article we continue our liner discussion with a focus on liner volume. One of the most important liner design variables is the internal volume. Larger internal volumes are preferred for general use because they minimize the chance of vapor...
Here we continue the discussion of inlet liners with a focus on liner outer diameter. It is important to realize that correct liner choice is most critical for:
Selecting an appropriate inlet liner from the myriad available liner choices is a daunting task, especially when there is little qualified technical information about what differentiates them in terms of actual performance. Here we start discussing...
Although gas chromatography has many positive attributes as an analytical tool, its incompatibility with labile and active compounds is certainly one of its biggest weaknesses. Here we discuss evidence of sample decomposition and what we might do to...
Continuing our saga of split sample introduction, here we discuss measuring gas flows and liner selection for split injections.
This technical article introduces the split sample concept and things to take note of for the best analytical results possible.
