The new 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 have the columns been made thinner but the suppressor module has also been 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.

Alongside the environmental benefits, microbore columns also require less frequent eluent preparation and thus improve accuracy and save time. Additionally, they can be used with small amounts of sample material and can therefore be perfectly interfaced with various inline detectors.
