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