Abstract
The present disclosure describes a field flow fractionator including (a) a top plate assembly including a top electrically conductive electrode, (b) an o-ring, (c) an electrically insulating frit, (d) an electrically insulating spacer between a bottom surface of the top electrode and the o-ring and the frit, (e) a membrane between the spacer and the frit, and (f) a bottom plate assembly including a bottom electrically conductive electrode.
Claims23
A field flow fractionator comprising:
- a top plate assembly comprising a top electrode, wherein the top electrode forms a top plate of the top plate assembly and includes a top electrically conductive surface;
- an o-ring;
- an electrically insulating frit;
- an electrically insulating spacer between a bottom surface of the top electrode and the o-ring;
- and
- a membrane between the spacer and the frit;
- and a bottom plate assembly comprising
- a bottom electrode,
- wherein the bottom electrode forms a bottom plate of the bottom plate assembly and includes a bottom electrically conductive surface, wherein the top electrode and bottom electrode are each constructed and arranged to receive bolts for coupling the top electrode and the bottom electrode.
