The price is for QTOF 2 Mass Spectrometer. HPLC system is sold separately. Please inquire.  It comes complete with EPCAS conversion, computer with Masslynx 4.1. The Waters Q-TOF II ( QTOF 2 ) Mass Spectrometer is an LCMSMS system that incorporates a simplicity of a quadrupole (MS-1) with the ultra-high efficiency of an orthogonal time-of-flight analyzer (MS-2). The Q-Tof 2 instrument utilizes the orthgonal time-of-flight analyser to achieve simultaneous detection of ions across the full mass range. This is in contrast to conventional instruments (e.g tandem quadrupoles) that must scan over one mass at a time. The Q-Tof 2 instrument offers up to 100 times more sensitivity than tandem quadrupole instruments when acquiring full product ion (MS/MS) mass spectra. The Q-Tof 2 has a mass-to-charge ratio (upper) limit in excess of m/z 20,000, in both MS and MS/MS modes, enabling the analysis of very large molecules as ultiply charged ions.  The high resolving power (10,000 FWHM) enables improved mass measurement accuracy for charge state identification of multiply charged ions and greater differentiation of isobaric species.  The inherent stability of the reflectron TOF analyser routinely delivers excellent mass measurement accuracy (~5ppm at 1000 Da). The Q-Tof 2 provides the ultimate in performance for high sensitivity de novo sequencing of sub femtomole quantities of peptides. 'PepSeq' Micromass’ multi-layered peptide sequencing tool is designed to take full advantage of the high resolution MS/MS data from the Q-Tof 2. Initially full product ion (MS/MS) spectra are automatically pre-processed with Micromass’ charge state de-encryption algorithm (MaxEnt-3). Sequence tags are then established to provide the cornerstone from which the complete amino acid sequence is extended to cover the C and N termini.     Note: Licenses for Waters’ software products are not transferable.
