New generation of microbore colums for environmentally friendly chromatography

New legislation such as the Clean Air and Water Act and a general trend towards green chemistry stipulate the use of environmentally friendly chemical products and processes.

Metrohm responds to this introducing a new generation of high capacity anion and cation exchange columns.

The new columns feature an inner diameter of only 2 mm enabling

  • lower eluent flow rates and
  • less solvent consumption.

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 volumes of sample and can be perfectly interfaced with various inline detectors.
