Equipment and Facilities
PI's Laboratories (SC 458/465): Our two research laboratories are equipped with five Schlenk lines that are supplied by four independent UHP Argon lines with moisture traps, four Edwards RV 12 oil pumps with vacuum gauges and one Welch 1400 DuoSeal Dual-Stage oil pump – all of them are outfitted with liquid nitrogen traps. We also have four solvent stills (dichloromethane, THF, diethyl ether, toluene, and hexanes), two rotary evaporators with a membrane pump, a deep freezer (–35° C), two regular refrigerators inside and one explosion-proof refrigerator nearby the lab. Three analytical balances, in the labs, two sonicators, eight dewar flasks and a 10 L storage dewar vessel for liquid nitrogen are available. Our drawers and cabinets are filled with (Schlenk) glassware for synthesis and related equipment. There is also a stock area for consumables in the main lab SC 465.
Moreover, since June 2019, the PI’s major lab houses a state-of-the art double MBraun Labstar Pro SP (1800/780) Glovebox with internal deep freezer (–35° C), feedthrough connections for external vacuum sources and cyclic voltammetry. The department has a CHI 660E workstation available to all research groups.
Solvent Purification System (SL 4040): Since 2018, the Department of Chemistry and Biochemistry houses a brandnew GC-SPS-7 Glass Contour 800L solvent purification system from Pure Process Technology. Seven different dry solvents under argon (dichloromethane, THF, diethyl ether, toluene, hexanes, acetonitrile, and methanol) are available to all chemistry research groups in the department, free of charge.
1) The 300 MHz NMR spectrometer (Bruker DPX 300), equipped with an autosampler and Variable Temperature control unit. The console was completely upgraded in Spring 2020.
2) A Bruker Avance III 400 MHz High Performance Digital NMR Spectrometer that features a Multinuclear Broadband Fluorine Observe (BBFO) probe with digital tuning covering the range from 15N to 31P as well as 19F with 1H decoupling, a BVT Variable Temperature control unit including a digital control module, and autosampler. This instrument was acquired in Spring 2017.
3) A Bruker Avance III 600 MHz High Performance Digital Spectrometer NMR with 1H, 13C, 15N PRODIGY cryoprobe that includes a SampleJet (automated sample changer for up to 96 samples) has become available to the Department and all research groups in Spring 2020.
Spectrofluorometer Facility (SC 239): A Steady-State and Time-Correlated Single Photon Counting (TCSPC) fluorescence Lifetime System for under 100 picosecond (PTI Picomaster 1) is available in the second floor of the Science building. In addition, a brand-new Horiba Fluorolog QM-75-11-C spectrofluorometer system with FM integrating sphere was acquired and sponsored by the Office of Research in Fall 2020.
EPR: The department houses a Bruker EMX EPR spectrometer that was upgraded with a a water-based cooling system and a variable-temperature unit (liquid N2) in 2018.
Mass Spectrometry Facility: Thermo Scientific LTQ XL Mass Spectrometer coupled with Heated Electrospray Ionization (HESI) source which can operate in three different mass ranges of 15 to 200 m/z; 50 – 2000 m/z; 200 – 4000 m/z and MS scan power (MSn) for n= 1 through 10. High resolution isolation (HRI) option in LTQ XL allows isolation of isobaric mass peaks. For more information, see Halim Group's website.
Other Instrumentation: Several Varian UV-Vis spectrometers (Cary 50 with fiber optic dip probe for in-situ UV-Vis spectroscopy, Cary 100, Cary 4000), an Advantage A Delta Nu Raman spectrometer, two Perkin-Elmer FT-IR and two Thermo-Nicolet FT-IR spectrometers are also available as shared instruments. Other instrumentation include a Shimadzu DSC-60 and TGA-50, 4 HPLC systems, 2 Agilent 5890 GC Instruments, and one Shimadzu QP-2010 GC/MS.
