A new FilterSpray™ module developed for the AccuTOF-DART Mass Spectrometer makes it possible to spot a sample on a disposable paper triangle for analysis by ambient ionization. The optional module is a simple alternative to Electrospray Ionization that eliminates the need for a special pump or plumbing, spray needle, desolvating gas, or precise alignment. The FilterSpray module is easily mounted onto the linear rail of the AccuTOF-DART, to permit FilterSpray analysis on the sample platform. Samples and solvent are deposited onto a paper triangles cut from a porous substrate such as filter paper or chromatography paper.
Typical applications for FilterSpray analysis include: polar and highly charged compounds, cationic and anionic compounds, thermally labile compounds, polymers, inorganic compounds and metals, peptides, digests, and small proteins. Samples can be analyzed without the risk of cross-contamination and sample carryover.
