Abstract
Slurries and methods of making slurries for modifying and extending relative humidity control ranges. The slurries may include a saturated aqueous salt and one or more other reagents selected to provide a controlled modifiable narrow range of relative humidity. The saturated aqueous salt may be one or more of sodium chloride, potassium chloride, potassium citrate, sodium formate, and/or magnesium chloride, and the one or more other reagents may be one or more of a lactate salt, glycerol, and/or an acetate salt, for example.
Claims11
A humidity control device for modifying and extending relative humidity control ranges, the humidity control device comprising:
- a water vapor permeable container;
- and
- a slurry contained within the container, the slurry comprising:
- a saturated aqueous salt, the salt comprising sodium chloride, potassium chloride, and magnesium chloride;
- and
- one or more other reagents;
- and
- a food grade additive that is optically active to be visible in visible light, the optically active food grade additive being riboflavin;
- wherein the slurry provides a controlled modifiable narrow range of relative humidity.
A humidity control device for modifying and extending relative humidity control ranges, the humidity control device comprising:
