Abstract
A system for separating an aqueous stream of mixed polynucleotides into a series of length-based polynucleotide fractions and collecting one or more of the length-based polynucleotide fractions into separate containers. The system comprises a separation column containing separation media for separating an aqueous stream of mixed polynucleotides into a series of length-based polynucleotide fractions; a container including one or more single-sample containers; an ejection chamber having a separated sample inlet for receiving the length-based polynucleotide fractions, a waste outlet for discharging uncollected sample, and a capillary-sized fraction outlet positioned to discharge a selected length-based polynucleotide fraction into a single-sample container. The system also includes means for effecting discharge of a selected length-based polynucleotide fraction into the separate container. The means for effecting discharge of a selected length-based polynucleotide fraction into a separate container can include a puff valve having a pressurized gas inlet and a puff gas outlet and the ejection chamber can include a puff gas inlet communicating with the puff gas outlet, whereby activatio…
