OGL

Facilities

Laboratory equipment includes:

Hewlett Packard (HP) gas-chromatograph (GC-HP 5890 series 2) an FID detector and two injectors (on-column and split/splitless) with EPC.

HP5973 MSD/DS-Diffusion, Electron Impact coupled to a GC- HP 6890 with on-column and split/splitless injectors with EPC.

The OGL gas chromatograph-isotope ratio monitoring mass spectrometer (d¹³C and dD) is located in the Environmental Isotope Geochemistry Laboratory (EIGL) in the Dept. of Earth and Environmental Sciences at UIC.

S2 Analyser (VINCI Technologie): preparative pyrolysis unit.

Centrifugation: Heraeus Sepatech 17S

Concentration: 2 rotari-evaporators and nitrogen gas lines

Ovens:

1 High temperature oven, annealing oven (Lindberg Blue, to 1100 ^oC)
2 Low temperature ovens to 200 ^oC

Water preparation: MilliQ, Ultrapure water system.

Organic solvent distillation line

Extraction:

Ultrasonic Extractor with microtip (Heat Systems, Ultrasonic, Inc.)
Sohxlet extractor (x12) and water chiller

Separation: Equipment required for thin layer chromatography (TLC) and column liquid chromatography (CLC) is available.

Freeze dryer: Labconco Freeze Dry System/Freezone 4.5

Elemental analysis: Carlo Erba, CHONS elemental analyser: Purchased with Hormoz Bassirirad from the Department of Biological Sciences. This instrument, located 4013 SEL, is able to achieve high precision quantitative analysis of elemental C, N, O, H and S. Elemental analysis is also done in EIGL.

U.V. spectrophotometry: Beckman DU-7 spectrophotometer

Computing facility: The organic geochemistry laboratory at UIC currently uses 3 IBM compatible personal computers, 1 HP Kayak workstation, 1 HP vectra workstation, and 3 laser printers. All students are equipped upon arrival with a personal computer belonging to OGL (x5).
Computerized spectral library:

Wiley 6th edition, 275K spectra.
Geochemical and Petrochemical compounds library 2nd ed., 1.1K spectra.
OGL spectral library: The OGL constructed during the last few years a library of all mass spectra of biomarkers published in geochemical journals. This library includes in excess of 2000 spectra of organic molecules of biogeochemical interest.
