Abstract:
1. A spirally wrapped chromatographic structure for absorption of analytes, comprising: an absorber layer having a first surface and a second surface, wherein one or a plurality of channels are defined in said first surface and wherein said absorber layer comprises two or more material compositions having different binding capabilities to said analytes; and a support layer having a first surface and a second surface, wherein said absorber layer and support layer are spirally wrapped wherein the first surface of the support layer is disposed on said second surface of said absorber layer, wherein said absorber layer and said support layer comprise a spiral configuration such that at least a portion of said first surface of said absorber layer contacts at least a portion of said second surface of said support layer and said channel(s) are arranged radially around the structure; wherein said support layer comprises an electrically resistive material at a thickness of 0.1 μm to 10,000 μm and capable of heating upon the application of a voltage and wherein said spirally wrapped chromatographic structure is configured to provide a flow rate in the range of 50 ml per minute to 30 liters per minute.
