Johnston Group Facilities

Our group infrastructure includes an MBRAUN inert atmosphere box (for organometallic chemistry or similarly water- and air-sensitive organic synthesis), two computer-driven HP-1100 HPLCs equipped with a vacuum degasser, 4-solvent mixing system, autosampler, 5-column changer, diode array UV-VIS detector, and chiral columns for asymmetric synthesis. We recently added a MS capabilities to one HPLC. A third HPLC is configured for semi-preparative separation work. A Varian GC is also equipped with autosampler and chiral columns for enantioselective reaction development. An in situ IR reaction monitoring (Mettler Toledo iC10) is used for mechanistic studies. An MPLC (rebranded, polished, and sold as a 'Combiflash') is also available for repetitive chromatography. Solvent can be removed directly from racks of chromatography tubes using our Genevac.
The chemistry building is wireless network accessible, and many students own laptop computers equipped with a wireless access card.
At the departmental level, an extensive lineup NMR instrumentation is readily available. Our group makes routine use of the more sophisticated 2D experiments to assign structure and stereochemistry to intermediates in our natural product total synthesis projects. We are very fortunate to have a machine shop, glassblowing, and purchasing facilities all within Chemistry. We are also grateful for a top-notch Chemistry Library housed in Stevenson Center.
