This instrument is housed in Clement 122. The chromatograph is a high-performance liquid chromatograph (HPLC) that is equipped with a sample collector. It is connected to an atmospheric-pressure chemical ionization/electrospray mass spectrometer. The mass spectrometer can be used without the HPLC. This instrument is primarily used in the Instrumental Methods of Chemical Analysis (Chem-312) laboratory, and by the research students of Professors Curran, Henderson and Prigodich.
