Abstract
The present disclosure describes a field flow fractionator including (1) a top plate assembly including (a) a first non-corrosive material, and (b) at least three fluid fittings machined (simpler) into the material, (2) a spacer, (3) a membrane, (4) a bottom plate assembly including (a) a second non-corrosive material, (b) a cavity machined into the second non-corrosive material, (c) a frit configured to be placed into the cavity, and (d) at least one bottom plate o-ring configured to seal the bottom plate assembly to the spacer, and (5) where the top plate assembly, the spacer, the membrane, and the bottom assembly define a separation channel. In an embodiment, the at least three fluid fittings including a fitting for an in-flow, a fitting for an out-flow, and a fitting for a cross-flow.
Claims8
A field flow fractionator comprising:
- a top plate assembly comprising
- a first non-corrosive material,
- at least one top plate o-ring, and
- at least three fluid fittings machined into the material;
- a spacer, wherein the top plate assembly is sealed to the spacer by the at least one top plate o-ring;
- a membrane;
- a bottom plate assembly comprising
- a second non-corrosive material,
- a cavity machined into the second non-corrosive material,
- a frit configured to be placed into the cavity, and
- at least one bottom plate o-ring configured to seal the bottom plate assembly to the spacer, wherein the spacer is one and only one spacer, and wherein the top plate assembly and the bottom plate assembly are sealed to the one and only one spacer;
- and
- wherein the top plate assembly, the spacer, the membrane, and the bottom plate assembly define a separation channel.
