Optimizing nanovial outlet designs for improved solid-phase extraction in the integrated selective enrichment target-ISET.
Förlag: Wiley-Blackwell Publishing
The integrated selective enrichment target is a microfluidic platform for SPE sample preparation with integrated nanocolumns, which simultaneously offers direct MALDI MS read-out. Here, we present a study on the importance of different nanocolumn outlet hole geometries and hole areas in relation to MS signal intensity and reproducibility. A design solution that provides the flow characteristics required for robust sample preparation using automated liquid handling is reported.
