One Summer in the Glovebox

Hydrate loss and phase change in a field reagent carried on groundwater rounds

A research poster from the School of Underlying Conditions follows nine bottles of ammonium heptamolybdate reagent through fourteen months in a laboratory cupboard and two sampling-vehicle gloveboxes, and finds that the glovebox bottles lost water of crystallisation in steps that fall in the hottest weeks rather than steadily with age. The bottles in the hotter glovebox also developed a second crystalline phase, while recovery of a phosphate standard stayed within 97–101 per cent for every bottle.
