How does magnetic-particle carry-over in QIAsymphony eluates need to be handled?
FAQ ID -2166

In general, magnetic particles are not carried over into QIAsymphony eluates. However, if high amounts of genomic DNA are purified (large number of white blood cells in the sample) magnetic-particle carryover may be observed. If carryover does occur, magnetic particles in eluates will not affect most downstream applications. If magnetic particles need to be removed before performing downstream applications, tubes or plates containing eluates should first be placed in a suitable magnet and the eluates transferred to a clean tube.
