HPLC Column Dimensions - Quick Guide

HPLC columns are manufactured in a variety of different internal diameter and length combinations, as well as having an assortment of particle sizes. 

HPLC column dimensions will affect the efficiency sensitivity, and speed of an analysis. The choice of column dimensions will depend on the chromatographic application; analytical, semi-preparative, preparative, number of analytes in the mixture etc.  However, the dimensions can also be altered to improve chromatography by achieving more efficient, sensitive, and faster analyses.  The primary column dimensions of particle size, length, and internal diameter will be discussed and their effect on chromatographic separations demonstrated, providing some practical insight into how to select the best column dimensions for a particular application...

The Why, What, and How of Headspace GC

The first question to ask is, why would headspace GC be a good sampling technique?

Headspace sampling is excellent for the qualitative or quantitative analysis of volatile species in samples that can be efficiently partitioned into the headspace gas volume from either a liquid or solid matrix.  It is also a good technique for the analysis of samples where the entire sample should not be injected into the GC instrument (i.e. dirty samples).  Headspace sampling is also particularly amenable to the analysis of trace levels of analytes.  

Typical examples of headspace analyses include...
