Abstract Information :

There is aways great interest in faster GC separations.  This can be achieved in difrent ways. From using narrow bore and shorter columns to  using faster carier gas/flow or temperaure program. The oven does have a limitation in program rate. By reducing oven volume, one can apply faster programming, reducing run time. Additionally, it is possible to predict (model) separations using a free web-tool called ProEZGC.  With this tool one can optimize separations of your components of interest. You can change type of carrier gas, column dimensions, flow and temperature programming and immediate see what it will do for your separations.  For many applications, optimization of analysis time, is a matter of making the model and enter the new conditions in your GC. Results ar remarkably close.
