The IonSpec QFT mass spectrometer remain the most sought after analytical instrument for high resolution, accurate mass determination in proteomics, drug discovery, and combinatorial chemistry. Versatile dissociation techniques offered with IonSpec FTMS include ECD, IRMPD, and SORI-CID.
The concept of a quadrupole FTMS was pioneered by IonSpec in 1983 and resulted in US Patent 4,535,235. Since that time, IonSpec has refined FTMS technology to the point that it represents today the ultimate in sensitivity, mass accuracy, and resolving power. The schematic below shows the QFT, a "triple quadrupole" FTMS with a dual orthagonal source. This new hybrid FTMS instrument has all the features of the traditional triple quad with the performance features and dissociation techniques of an FTMS. Powerful data-dependent LC/MS/MS analysis and "top-down" proteomics experiments can be performed on the QFT.
The quadrupole "front end" of the QFT is available as an upgrade for existing IonSpec customers, making it easy for them to stay at the leading edge of technology. It also features the world's first maintenance-free superconducting magnets. These magnets never require any liquid helium or liquid nitrogen, and they are unique to the QFT. An option for doing LC/MALDI is also available with the MassTech AP-MALDI source.
