Patented AnchorChip™ targets are polished steel targets with hydrophilic sample and calibrant spots surrounded by a hydrophobic barrier for MALDI sample preparation. Sample positions on contain "anchors"; hydrophilic patches surrounded by a hydrophobic ring.

The "anchor" localizes droplets at the sample position and the hydrophobic ring prevents sample spreading and concentrates the sample into a spot between 0.4 and 2 mm in diameter.

The localization effect ensures that every single laser shot fired throughout an automatic run will hit a sample spot. This significantly increases the efficiency of the MALDI acquisition process.
