A multichannel capillary column having an interior wall defining a single internal bore, wherein the interior wall forms a plurality of n channels and n ridges wherein adjacent channels are partially separated by a respectively interposed ridge and wherein a central, coaxial portion of the internal bore communicates with each of channels to allow cross-channel fluid communication between all of the n channels.
A method of making a multichannel capillary column, comprising the steps of:
- forming an interior wall with a plurality of n channels and n ridges, wherein the adjacent channels are partially separated by a respectively interposed ridge such that an internal bore is formed having a central, coaxial portion that communicates with each of the channels, whereby cross-channel fluid communication is established between all of the n channels.
A multichannel capillary column having an interior wall defining a single internal bore that can be encompassed by a circle having a diameter lmm, wherein the interior wall forms a plurality of n channels and n ridges wherein adjacent channels are partially separated by a respectively interposed ridge and wherein a central, coaxial portion of the internal bore communicates with each of the channels to allow cross-channel fluid communication between all of the n channels.
