摘要:
A sensor including a substrate and a sensing element disposed on a substrate is provided. The sensing element includes a sensing matrix in contact with a flow of water, an indicator for one or more chemical species in the flow of water, and a selectivity component that reacts reversibly with the one or more chemical species. The sensor also includes a light source configured to direct light through the substrate and the sensing element. The sensor further includes a light detector configured to receive transmitted light from the substrate and the sensing matrix and to generate a signal representative of selective wavelengths of the light indicative of the one or more chemical species in the flow of water.

A fluid path system includes a vial containing a pharmaceutical product therein. A dissolution fluid path is also included in the fluid path system, the dissolution fluid path having an output end in fluid communication with the vial and an input end attached to a pressure vessel containing a dissolution medium. A delivery fluid path is also included in the system having a first end hermetically attached to the vial to transport therefrom a mixture of dissolved pharmaceutical product and dissolution medium and a second end connected to a receiving vessel to receive the mixture. A dissolution fluid path valve is positioned between the pressure vessel and the dissolution fluid path to control flow of the dissolution medium, and a delivery fluid path valve is also included in the fluid path system to control flow of the mixture from the delivery fluid path to the receiving vessel.
摘要:
A method for dynamic filtration of a pharmaceutical product is provided. The method includes using an unconditioned resin configured to selectively retain one or more components from a mixture having the pharmaceutical product and where the unconditioned resin is configured to be activated by a medium of the mixture. The method further includes the use of at least one positioning material disposed adjacent to the unconditioned resin, where the positioning material is configured to provide mechanical support to the resin to at least partially retain the resin in position.
