Abstract
A cartridge for use in conjunction with a target analyte permeation testing instrument and method for measuring transmission rate of a target analyte through a prefilled package or container using the cartridge. The cartridge includes an open ended vessel, a first end cap capable of repeated sealed engagement over one of the open axial ends of the vessel, a second end cap in sealed engagement over the other open axial end of the vessel, an entrance port for providing fluid communication from a source of carrier gas to the void volume of the vessel, and an exit port for providing fluid communication from the void volume of the vessel to a target analyte sensor.
Claims9
A cartridge for use in conjunction with a target analyte permeation testing instrument for measuring transmission rate of a target analyte through a prefilled package or container, wherein the target analyte permeation testing instrument includes a line carrying a target analyte free carrier gas from a source of the carrier gas to a target analyte sensor, characterized in that the cartridge comprises:
- (a) a metal cylindrical vessel defining a void volume and having open axial ends with a ferrule at each axial end of the cylinder,
- (b) a first metal end cap capable of repeated sealed engagement over one of the open axial ends of the vessel when in a closed position, and unsealed disengagement from over the one open axial end of the vessel for providing access to the void volume of the vessel when in an open position,
- (c) a second metal end cap in sealed engagement over the other open axial end of the vessel,
- (d) an entrance port configured and arranged for connection with the line for providing fluid communication from the source of carrier gas to the void volume of the vessel, and
- (e) an exit port for connection with the line for providing fluid communication from the void volume of the vessel to the target analyte sensor, and
- (f) a first sanitary clamp operable for releasably axially compressing the first end cap onto to the cylinder.
