PaperSpray® Accessory for AccuTOF™-LP and AccuTOF™-DART® Systems March 4, 2020 8. PaperSpray, AccuTOF™ DART®, Application Note, Mass Spectrometry (MS) 0 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 For full details: Attached files often contain the full content of the item you are viewing.
