Ten miles off the Californian coastline, at the bottom of the Santa Barbara channel, domes rise from the Pacific Ocean floor. A paper published on-line in the journal Nature Geoscience identified these as a series of unusual underwater volcanoes.

In ion chromatography, the presence of a large amount of matrix ions makes quantification of the target ions difficult. Selective removal of matrix ions - matrix elimination - can be performed by treating a sample with a solid-phase extractant. Halides can be removed by precipitation with silver, which is present as a counterion in a cation-exchange resin. A subsequent treatment with a cation-trapping column removes residual dissolved silver ions.

The Application Notebook
Traditionally, summer is a time when the worlds of lab research and business slow down to a large extent. If you work in academia, chances are many of your students have returned home for the summer and the teaching load has been reduce, while those of you working in private industry and research labs may see coworkers taking long-anticipated (and well-deserved) vacations.

Waters UK has reported that it is now a distributor of RECIPE consumable products.
A separation based on molecular size using GPC with organic eluents was demonstrated, along with a simple sample preparation procedure. Since this GPC application uses DMF and a small amount of lithium bromide as mobile phase, it will work on a standard HPLC system without any modifications. The molecular weight ranges (Mw) of the polyacrylonitrile samples analyzed were found to be in the middle of the linear calibration range.

It always seems to be the case that time flies when you are either busy or having a good time, so as we reach this, the last day of LCGC's and Spectroscopy's coverage from ASMS 2010 from Salt Lake City, we certainly hope that time has flown for all of you. However, before everyone heads off to their next destination tomorrow, whether that be home or another industry event, there is still a great deal of science and technical material to take in.
