wherein one or more edges of the second end of the plurality of walls are beveled, sloped, multiply sloped, and/or triangular in profile.
5. The method of claim 4 , wherein melting is facilitated by applying heat, radiation or ultrasonic power.
6. The method of claim 5 , wherein application of heat comprises applying pressure to the first and/or second ends of the plurality of walls via a plate for a predetermined period of time.
7. The method of claim 4 , wherein said filling comprises filling the plurality of the compartments with sorbent material to full capacity from the first membrane to the second membrane.
8. The method of claim 4 , wherein the melting is performed at a temperature ranging from the Glass Transition Temperature (Tg) to the Melting temperature (Tm) of the wall material.
9. A sorbent cartridge manufacturing method comprising:
providing a frame comprising a first side, a second side, a plurality of compartments each configured to hold sorbent material, a plurality of respective walls arranged to form and separate the plurality of compartments, wherein a first end of each wall is arranged on the first side and a second end of each wall is arranged on the second side;
arranging a first air and/or fluid permeable membrane on the first side,
melting at least a portion of the first end of the plurality of the walls, wherein portions of the first permeable membrane lying adjacent the melted portion of the first end bond with the melted portion thereby affixing the first permeable membrane thereto;
filling the plurality of the compartments with sorbent material;
arranging a second air and/or fluid permeable membrane on the second side, and
melting at least a portion of the second end of the plurality of the walls, wherein portions of the second permeable membrane lying adjacent the melted portion of the second end are configured to bond with the melted portion thereby affixing the second permeable membrane thereto,
wherein
melting is facilitated by applying heat, radiation or ultrasonic power,
application of heat comprises applying pressure to the first and/or second ends of the plurality of walls via a plate for a predetermined period of time, and
the plate is configured with apertures, at least a portion of which correspond with the one and/or another of the plurality of compartments.
10. A sorbent cartridge sealing system, the cartridge comprising a frame including a first side, a second side, a plurality of compartments each configured to hold sorbent material, a plurality of respective walls arranged to form and separate the plurality of compartments, wherein a first end of each wall is arranged on the first side and a second end of each wall is arranged on the second side, the cartridge further comprising a first air and/or fluid permeable membrane arranged on the first side and a second air and/or fluid permeable membrane arranged on the second side, the system comprising:
