This month we look at a simple and structured approach to developing a reversed phase Solid Phase Extraction (SPE) method. We’ve provided an interactive tool to allow you to evaluate different sets of conditions and see what effect they have on the resulting chromatogram. more »
My GC Detector Flame Won’t Light
1) Before switching on gases, set the temperature of the detector and allow to equilibrate for at least 30mins after reaching operating temperature. This ensures all surfaces are hot and dry, creating the right.

Checklists are only for pilots?
1) Mobile phases on correct pump line
2) Sufficient mobile phase present to complete analysis of full run
3) Each mobile phase line purged with at least 30ml more »

Translating GC and GCMS Methods
In this session, Dr. John Hinshaw and Tony Taylor explore the various reasons for translating methods including improved chromatography, faster throughput, adopting modern column geometries and switching to hydrogen carrier from helium. Thursday 18th July 2013 - 11am EST / 4pm GMT Register Here »
Buffer choice for HPLC separations
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.
