To achieve dry air, a desiccant column is provided that should be filled with magnesium perchlorate. A small amount of glass wool should be placed towards the outlet of the column, and the column should then be filled with magnesium perchlorate using a spatula. When the column is full, it should be tapped on the desk to settle the magnesium perchlorate and then re-filled.
The rubber bung should then be inserted in the column to compress the magnesium perchlorate so that the column is tightly packed. The column should be mounted VERTICALLY on the lab stand. Mounting the desiccant column vertically, as well as improving its drying ability, will help minimize any risk of liquid magnesium perchlorate entering the sensors.

The desiccant column holds only enough magnesium perchlorate to dry gas for a typical 3 hour experiment. The column must be re-filled after every use, even if the desiccant appears dry. Magnesium perchlorate, when saturated, forms a solution that may enter and damage the sensors or other components. Qubit Systems accepts no responsibility for components damaged by such negligence.

Note that magnesium perchlorate supplied with the G144 and the N2 Fixation package has the correct mesh size for use in experiments. Smaller mesh sizes (especially powders) may restrict gas flow through the sensors.
