J. Calvin Giddings provided one of the most practical discussions of the advantages of temperature programming in GC over isothermal analysis back in 1962. Here, Kevin Schug describes some of the salient points of that discussion and how they still apply today.

The nature of retention time changes in HPLC tends to fall into categories. Firstly, the retention time may "drift" over several injections or several analytical campaigns and secondly, the retention time may suddenly "jump to a different value between injections or between analytical campaigns (i.e. analyte retention times are very different to when that method was run last).

Oceanographers have extremely challenging analysis problems to overcome. Can analytical chemists help? The Collaborative on Oceanographic Chemical Analysis workshop, sponsored by the National Science Foundation, connects scientists in these two fields to exchange ideas. And that is good, because the needs are great. Kevin Schug takes a look at where that collaboration might lead.
