PaperSpray® Accessory for AccuTOF™-LP and AccuTOF™-DART® Systems

PaperSpray Principle

Samples and a polar solvent such as methanol are deposited onto a porous substrate such as filter paper or chromatography paper cut into a triangle. When a high voltage (typically ~3000V) is applied, Electrospray Ionization (ESI) occurs at the tip of the paper triangle. PaperSpray is simpler than ESI and does not require a pump, spray needle, desolvating gas or precise alignment.

PaperSpray Ionization

  • Rapid and convenient ambient analysis of compounds that can be analyzed by electrospray ionization
  • No pump
  • No tubing or connectors
  • No spray needle or gas connections
  • Disposable paper triangles eliminate sample carryover problems
