In our July issue: COLUMNS: COLUMN WATCH When are Sub-2-µm Superficially Porous Particles Needed in LC?
The use of superficially porous particles (SPPs) for modern high performance liquid chromatography (HPLC) is now very common. Initially, SPPs rose as an alternative to sub-2-µm fully porous particles (FPPs). In recent years, many column manufacturers have developed 2-µm and smaller SPP-based products. This article investigates the practical utility of these smaller SPP designs. Read more >>

This is the first of three articles looking at the impact of the new USP <1058> on Analytical Instrument Qualification (AIQ) on data integrity in a regulated chromatography laboratory. Read more >>
GC CONNECTIONS How to Get the Most From Your Inlet
Split and splitless injections present several well-known and some not-so-well known challenges, mostly arising from heating of the inlet, that make sample injection and inlets a major hurdle for gas chromatographers.
