    摘要: A sorbent media protective device includes an enclosure having a gas inlet, gas outlet and a thin-film multilayer indicator. The thin-film multilayer indicator is proximate sorbent media that can sorb a vapor of interest flowing from the gas inlet towards the gas outlet. The indicator includes a porous detection layer whose optical thickness changes in the presence of the vapor, located between a semireflective layer and a reflective layer permeable to the vapor. With equilibration at the applied vapor concentration between at least a portion of the media and the vapor, the vapor can pass through the reflective layer into the detection layer and change the detection layer optical thickness sufficiently to cause a visibly discernible change in the indicator appearance if viewed through the semireflective layer.

    摘要: Multi-layered optical sensor films are disclosed. The sensor films include a first reflective layer, a detection layer over the reflective layer, and optionally a second reflective layer over the detection layer. The detection layer contains a hydrophobic, amorphous, substantially microporous, analyte-sensitive organosilicate composition. The analyte-sensitive organosilicate composition provides an optical change in the film upon analyte exposure.

    摘要: Methods of correlating a monitoring device to the service life of a filter cartridge include providing a monitoring device, and calibrating the monitoring device to correspond to the service life of a filter cartridge. The monitoring device comprises a demand substance within a receptacle, a sensing element with a detection point, a reader for the sensing element, and a fluid delivery device. Calibration includes determining the ratio of the residence time of the monitoring device to the residence time of the filter cartridge, and utilizing the ratio to correlate the response of the sensor within the monitoring device to the service life of the filter cartridge. The response of the sensor is correlated to the service life of the filter cartridge by control of the fluid delivery parameters of the fluid delivery device. The fluid delivery parameters include the flow rate, the demand substance mass, the receptacle cross sectional area, the receptacle volume, the receptacle length, and the demand substance packing density.

    摘要: Devices for monitoring the end of service life of a filter cartridge include a demand substance, a sensing element with a detection point located within or adjacent to the demand substance, a reader for the sensing element, and a fluid delivery device. The detection point of the sensing element is correlated to the service life of a filter cartridge. The correlation is effected by correlation of the residence time of the monitoring device to the residence time of a filter cartridge. The residence time of the monitoring device is correlated to the residence time of the filter cartridge by control of the fluid delivery parameters of the fluid delivery device. The fluid delivery parameters include the flow rate, the demand substance mass, the receptacle cross sectional area, the receptacle volume, the receptacle length, and the demand substance packing density of the monitoring device.
