The spectrometer uses a standard 6 lamp auto-aligning turret (using data-coded or un-coded lamps, each with its own power supply) and Stockdale double beam system with Quad-Line deuterium background correction. The optical system covers the range 185nm to 760nm as standard, with an optional wide range PMT up to 900nm. The spectrometer is equipped with GFS97 Graphite Furnace, GFS97 furnace auto-sampler, which can run up to 60 samples continuously using up to 6 standard solutions. S Series Atomic Absorption Spectrometer (located in room 152) Shimadzu GC-14A Gas Chromatograph equipped with FID Detector (located in room 152) The column is a 10% Carbowax 20 micron with 80/100 Chromosorb WAW support 6 ft long 1/8 inch in i.d. Multi-linear programming capability can use up to a maximum of five staged increments within no more than time 655 minutes collection run time.ĭata is recorded via the Shimadzu CR601 Chromatopac integrator. ![]() The GC system is fully programmable (time & temperature). Shimadzu GC-14A Gas Chromatograph equipped with TCD Detector (located in room 152) Gas chromatograph data is obtained with the HP 6890 series integrator. Linear dynamic range: Minimum detectable: > 18 mCoul/gm carbon: helium carrier, 0.018-in. > 22mCoul/gm carbon: nitrogen carrier, 0.018-in. > 15 mCoul/gm carbon: helium carrier, 0.018-in. Stray light - 18 mCoul/gm carbon: nitrogen carrier, 0.018-in.EP resolution test - >1.6 toluene in hexane, ratio abs.Specifications 8453 UV-Visible Spectrophotometer: The instrument is controlled via the GRAMS/AI software which allows for standard data processing such as baseline correction (multi-point, polynomial fit), Peak fitting (Gaussian, Lorentzian, Voigt and other functions), Smoothing, Derivatives, Automatic spectral subtraction, and Spectral unit conversion. The wavelength range is from 7,800 to 350 cm-1. The sample compartment is accessible from front side. All models are step selectable down to 32cm-1. The spectrometer provides a full range of resolution, from 2cm-1 for routine analysis up to 0.5cm-1 for high resolution work such as gas analysis. MIDAC FT/IR Spectrometer (located in room 152) (1 scan accumulation, 4 cm-1 spectral resolution, measured peak maxima deviation from peak position 3060.02 cm-1).Wavelength accuracy Better than 0.1 cm-1 at 1,600 cm-1.(4 cm-1 spectral resolution, 5 second data collection time, room temperature, KBr optics, DTGS detector). ![]()
