Descrizione

Descrizione generale

Drierite^™ (CaSO₄) is widely employed as a chemical desiccant in laboratories. Its use is preferred over silica gel for the estimation of CO₂. It acts as a drying agent by absorbing moisture in air to form CaSO₄ hemihydrate.[1]

Applicazioni

Drierite^™ (CaSO₄) was used in Drierite^™/Ascarite column for the purification of air during the estimation of CO₂ production by flow-through respirometry system.[2]
it may be employed as drying agent in the following studies:

• For the removal of water via adsorption during the gas-chromatographic estimation of methanol, ethanol and isopropanol in biological samples.[3]
• As scrubber for the drying of air.[4]
• For the drying of nitrile samples during the calorimetric estimation of their enthalpies of vaporization.[5]
• For the removal of water vapor during the coulometric estimation of carbon dioxide for air pollution monitoring.[6]
