Agilent 6120 LC/Mass Spectrometer

Agilent 6120
LC/Mass Spectrometer

This instrument includes an Agilent model 1200 Agilent HPLC system interfaced to an Agilent 6120 Time-of-Flight mass spectrometer. Both dual ESI and APCI/ESI ionization sources. In addition to the mass detector, the HPLC also has in line diode array UV/Visible detector. Spectra are analyzed using Applied Biosystem’s Analyst and the open source mMass software.

Varian ProStar Analytical/Preparative System

Varian ProStar Analytical/Preparative System

This system is capable of both analytical and preparative scale separations. It has two ProStar 210 solvent delivery systems supporting flow rates up to 25 mL/min, a ProStar 335 dual path diode array UV/Visible detector, and a ProStar 410 fraction collector. Chromatograms are collected and analyzed using Varian's Galaxie software.

5 Cary UV/Visible Spectrophotometers

The department has 4 Cary-50 UV/Visible spectrophotometers, each having a Peltier temperature control unit. The department also has a high resolution UV/Visible spectrophotometer that contains Cary-14 optics, and which has been recently upgraded with OLIS electronics and software.
