Abstract
Printing one or more layers using toner and/or laminates to form one or more multi-channeled layers, with a particular pattern, including forming a desired image, for example, electrographically, on a receiver member. The multi layered channel printing apparatus and related method and print incorporates one or more static layers, and one or more moveable layers that allow a fluid to move through the micro channels via an opening or through a direct fill. It also incorporates particles in the channels to act as a packing material for separation of components of samples. The packing material can either be applied directly or using the electrographic printing process. An optional capping layer or substrate may then be applied.
Claims20
A printing method of manufacturing a chromatographic column structure comprising:
- depositing a static layer of toner to form a predetermined multi-channeled layer;
- depositing a second layer of one or more toner nodes over the static layer;
- depositing a top layer of laminate over said toner nodes, said top layer and the multi-channeled layer defining an expansion space, including one or more channels, adjacent said toner nodes;
- filling the one or more channels with a particulate material that has an affinity with a material to be separated from any fluid that is pumped into the channels;
- fusing the toners to form a fused toner channels with nodes that are bonded to the top laminate with the particulate material in the fused toner channels;
- and
- wherein the toner channels include an entrance port through which a fluid having the material to be separated can be pumped though the particulate material in the one or more channels.
A printing method of manufacturing a particulate filter comprising:
- depositing a static layer of toner to form a predetermined multi-channeled layer;
- depositing a second layer of one or more toner nodes over the static layer;
- depositing a top layer of laminate over said toner nodes, said top layer and the multi-channeled layer defining an expansion space, including one or more channels, adjacent said toner nodes;
- filling the one or more channels with a particulate material that has an affinity with a material to be separated from any fluid that is pumped into the channels;
- and
- fusing the toners to form a fused toner channels with nodes that are bonded to the top laminate with the particulate material in the fused toner channels;
- and
- wherein the toner channels include an entrance port through which a fluid having the material to be separated can be pumped though the particulate material in the one or more channels.
A method for electrographic printing of one or more multi-channeled layers upon a receiver, said printing comprising the steps of:
- depositing a static layer of toner to form a predetermined multi-channeled layer;
- depositing a second layer of one or more toner nodes over the static layer;
- depositing a top layer of laminate over said toner nodes, said top layer and the multi-channeled layer defining an expansion space, including one or more channels, adjacent said toner nodes;
- filling the one or more channels with a particulate material that has an affinity with a material to be separated from any fluid that is pumped into the channels;
- fusing the toners to form a fused toner channels with nodes that are bonded to the top laminate with the particulate material in the fused toner channels;
- and
- wherein the toner channels include an entrance port through which a fluid having the material to be separated can be pumped though the particulate material in the one or more channels.
