MicroTherm 40

The smallest column oven in the world

The temperature of a chromatographic column is an important value for:

  • constant and reproducible retention times of peaks
  • keeping the selectivity stable
  • prolonging the column life time

Although all chromatography users are aware of this issues and most analytical column are thermostated there was no oven available for micro and nano columns.

Especially small ID columns with very low mass are significantly influenced by the external temperature due to the low mass. Any ambient changes will effect an immediate response. Not only the flow rate is changing, but also the selectivity. If these two parameters fluctuate, no constant retention time can be achieved.

SunChrom developed the very small column oven MicroTherm 40 accommodating micro or nano column up to 1 mm ID and 150 mm length. The column oven is adjusted to 40 °C during the production matching the most commonly used temperature setting. It can be regulated by a small controller on the left side ±10 °C up and down. Without display the dimensions could be downsized to the minimum of approx. 35 x 4 cm and is therefore the smallest oven on the market!
