May 19, 2010New legislation such as the Clean Air and Water Act and a general trend towards green chemistry stipulate the use of environmental friendly chemical products and processes. Metrohm responds to this introducing a new generation of high-capacity anion exchange columns. The columns feature an inner diameter of only 2 mm enabling lower eluent flow rates and less solvent consumption. Moreover, environmentally benign carbonate/bicarbonate solutions are used with the columns for most anion separations. Not only the columns got thinner but also the suppressor module was scaled down, leading to reduced consumption of regenerant solution: for complete regeneration, as little as 2 mL acid (1 mol/L) is sufficient and no exchange of cartridges or membranes is necessary. Besides the ecological benefits, microbore columns require less frequent eluent preparation and thus improve accuracy and save time. Additionally, they get along with only small amounts of sample material and can be perfectly interfaced with various inline detectors. Source: Metrohm

Slow and Steady Wins the RaceIn the 100 years since Marie Curie won the Nobel Prize in Chemistry, women have made leaps and bounds in science and engineering. Following the extreme example of Madame Curie, women have exponentially raised their position in S&E in the last few decades. In a field previously (and traditionally) dominated by men, women seem to be slowly but surely taking over—or at least leveling the playing field. ...continue
