We take a look at the important topic of buffer choice for HPLC separations, how to the choose the correct buffer type and concentration as well as how to avoid variability in retention and selectivity. More »

Microextraction techniques are gaining popularity due to the fact that they are green, efficient, and easy to perform.  This elearning module will introduce single drop microextraction (SDME) and solid phase microextraction (SPME) using interactive content to clearly demonstrate how each technique works.  Detailed information is provided on the parameters which should be optimized to achieve the best extraction efficiency.

Leaks in GC-MS are particularly insidious.  How do you know when you have a leak and where do you start to look for it.  It is something that will happen to all chromatographers at some point.  Here is our quick guide to how to identify the source of GC-MS leaks. More »

Following a published method is great when it works, however, what happens when the chromatography fails and you don’t understand why there are certain components in the mobile phase?  Or when you look at a method and don’t understand it? More »
