Q Exactive Plus (Q)

The Thermo Scientific Q Exactive Plus benchtop LC-MS/MS combines high-performance quadrupole precursor selection with high resolution, accurate-mass (HR/AM) Orbitrap detection to deliver high performance and tremendous versatility. With a fast scan speed and multiplexing capabilities, the Q Exactive Plus mass spectrometer is an outstanding detector for fast chromatography separation techniques. The superior quality of Q Exactive Plus MS/MS data enables identification and quantitation of more compounds with greater confidence. The Q Exactive Plus LC-MS/MS system not only offers broad screening capabilities but also excels at targeted quantitation experiments.
