evaporated, e.g. using a rotary evaporator, as otherwise water saturation of the support will not be achieved during the elution step because of partitioning on the surface. The loaded support material is soaked for two hours in approximately 5 ml of water and the suspension is poured into the microcolumn.

RISK ASSESSMENT: USE OF REDUCED PRESSURE OR VACUUM

The exhaust of rotary pumps may be contaminated chemically but will also contain an oil mist from the pump itself. There is a danger of explosion if the exhausts of rotary pumps that are pumping large volumes of air or other gas are blocked or obstructed. Diffusion pumps are heated to boil the pumping liquid and so present a risk of burns.
