Abstract
A method includes receiving a wearable monitoring device worn by a user and information indicative of an amount of time the wearable monitoring device was exposed to an environment; extracting one or more compounds from the wearable monitoring device; analyzing the extracted compounds; and, based on the analysis of the extracted compounds and the information indicative of the amount of time, determining information indicative of the user's exposure to the compounds in the environment.
Claims17
A method comprising:
- purifying a silicone wearable monitoring device, including exposing the wearable monitoring device to one or more of (i) a solvent treatment including agitation of the wearable monitoring device in a solvent at a temperature of at least 33° C., the solvent comprising one or more of methanol, hexane, or ethyl acetate, or (ii) a heat treatment including heating of the wearable monitoring device at a pressure of less than 550 mm Hg to remove target compounds from the wearable monitoring device,
- wherein, when the purified wearable monitoring device is exposed to a subsequent solvent treatment or heat treatment, a weight of the purified wearable monitoring device is reduced by less than about 0.2%.
A method comprising:
- purifying a silicone wearable monitoring device to remove target compounds from the wearable monitoring device, including exposing the wearable monitoring device to one or more of a solvent treatment including agitating the wearable monitoring device in a solvent at a temperature of at least 33° C., the solvent comprising one or more of methanol, hexane, or ethyl acetate, or (ii) a heat treatment including heating of the wearable monitoring device at a pressure of less than 550 mm Hg;
- providing the purified silicone wearable monitoring device to a user, wherein, when deployed by the user, the purified wearable monitoring device comprises an absorbent material without a housing;
- and
- sequestering the target compounds from an environment in the absorbent material of the purified monitoring device when deployed by the user.
