Fluidic separation devices and methods with reduced sample broadening are provided. A column is located downstream from a holding chamber, and a flow providing means provides fluid flow effective to convey a sample along a flow path that extends from the holding chamber into the separation column. The sample is typically focused in the flow path upstream from the separation column. Optionally, the invention may be employed with electrospray mass spectrometry and in microfluidic applications. |
