Abstract: Some embodiments of the present disclosure relate to a method that includes disposing a vapor pump partially within an enclosure, such that the vapor pump is in fluid communication with the enclosure and an external environment, and where the enclosure comprises at least one vapor. In some embodiments, a portion of the at least one vapor is transferred with the vapor pump from the enclosure to the external environment. In some embodiments, a change in at least one parameter related to a mass of the at least one vapor within the enclosure is measured. In some embodiments, a rate of the portion of the at least one vapor transferred with the vapor pump from the enclosure to the external environment is calculated. In some embodiments, the rate of the portion of the at least one vapor transferred from the enclosure to the external environment with the vapor pump is calculated based on the change in the at least one parameter.

Abstract: A desiccant member is disclosed that comprises a polymer material and a bentonite material. The desiccant member is capable of absorbing moisture from an atmosphere containing siloxanes, organic compounds having a boiling point greater than 60 C, or mixtures thereof. The desiccant member is contamination resistant and may be regenerable. The desiccant member may have a high working moisture capacity that is suited for demanding environments.
