Agilent LC-TOF 6230


The Agilent TOF 6230 is an accurate mass instrument based upon time-of-flight technology. The instrument  accommodates several different solution-based atmospheric pressure ionization sources including electrospray (ESI). The instrument can acquire data in positive or negative ion mode. Agilent MassHunter software is used for data acquisition and data processing.  The software package includes modules for determining elemental composition, molecular feature extractor, deconvolution, et cetera. Instrument characteristics include:

  • LC pumps can handle up to 8000 psi
  • Mass Range of up to 10,000 Daltons (singly-charged)
  • Mass Accuracy of better than 3 PPM
  • Resolution (FWHM) 30,000 for mass 1000
  • Rapid switching between positive and negative ion modes

The instrument is located in 1238 Hach Hall.  Enquiries should be directed to Dr. Kamel Harrata (
