Experience the power of Thermo Scientific™ mass spectrometers without the hassle of liquid chromatography with PaperSpray. The PaperSpray technology enables highly sensitive and selective screening of compounds from biological matrices.

With PaperSpray, automated sample extraction from dried biological samples is accomplished with solvents. Only 5-12µL of biofluid is required per complete analysis. The analysis involves depositing the sample directly onto a paper cartridge. The sample is absorbed into the paper and allowed to dry, after which it is inserted into the Velox 360 system. The Velox 360 system loads the cartridge, deposits the solvent onto the cartridge, and positions the cartridge in front of the mass spectrometer inlet. The solvent acts to dissolve and elute the analytes of interest. A high voltage is then applied to the cartridge, vaporizing and ionizing analytes by electrospray. This electrospray is analyzed by the mass spectrometer. PaperSpray benefits include the following:

Simplicity: Complicated liquid chromatography and off-line sample preparation are eliminated.

Time Savings: High-throughput screening and quantitation of unprocessed biological and forensic samples is enabled quickly and efficiently.

Automated Workflow: The Velox 360 PaperSpray system introduces the sample to the mass spectrometer. A high voltage is applied to the paper cartridge, producing an electrospray of the deposited sample.

This commercially available PaperSpray source from Prosolia is co-marketed and sold by Thermo Fisher Scientific.
