Overview

The Department of Chemistry at East Carolina University is equipped with two mass spectrometers (MS): an Agilent 6890 gas chromatograph (GC) coupled to a JEOL double-focusing mass spectrometer, and a Waters Acquity ultra-high performance liquid chromatograph (LC) paired with a Micromass quadrupole/time-of-flight mass spectrometer (Q/ToF). Currently, we are evaluating the usage of the instruments to determine what rates to charge in the near future.

LC/MS (Q/ToF) samples: Appropriate samples are less volatile, higher molecular weight analytes amenable to Electrospray Ionization (ESI) or Atmospheric Pressure Chemical Ionization (APCI).

GC/MS samples: Samples should be low molecular weight (< 500 Da) and volatile. Electron Ionization (EI) and Chemical Ionization (CI) are the ionization techniques available on this instrument.
