Agilent 6538 UHD Accurate-Mass Q-TOF LC/MS G6538A

The Agilent 6538 UHD Accurate-Mass Quadrupole Time-of-Flight (Q-TOF) LC/MS system features Ion Beam Compression (IBC) and Enhanced Mirror Technology (EMT) for significantly improved mass accuracy and resolution. The 6538 Q-TOF features dual ESI technology. These new UHD Q-TOF systems, deliver exceptional sensitivity, dynamic range, isotopic fidelity, mass accuracy and resolution to meet your most challenging research needs.

Low Resolution ESI Spectrum

The low resolution 6538 ESI-­MS report consists of a profile mass spectrum showing m/z versus intensity. Peaks are labeled with m/z values rounded to one decimal place. The standard data acquisition range is m/z 90 -­1000 Da but printed mass spectra are normally expanded to display an appropriate region of interest.

Molecular Formula Generation (MFG) Accurate Mass Report

The MFG Report contains information pertinent to molecular formula determination and the high resolution mass spectrometry (HRMS) value. All of the values contained in the report correspond to the ionic species of interest and the given ionic formula includes the charging agent – e.g. [M+H+]+. Therefore, both the measured and calculated values are corrected for the mass of the electron (0.00054 Da) and should be reported as m/z.
