Sample, wash and elution solvents flow through the sorbent in one direction. SPE cartridges are not automation compatible.
SPE 96- well plate
Sample, wash and elution solvents flow through the sorbent in one direction. 96-well plates do offer automation, but additional hardware like a vacuum or positive pressure manifold is required.
INTip SPE utilizes a patented technology known as Dispersive Pipette XTRaction. This device is unique from all other SPE devices because sorbent is loosely contained within a pipette tip. The disperser helps to perturb the sample solution and loose sorbent during aspirate and dispense steps. This mixing provides a highly efficient interaction of the sorbent with the analyte of interest resulting in ideal analyte recoveries.
