Spectrometer surfaces

The contribution of spectrometer surface scatter depends upon the design, quality, and alignment of the spectometer components. Surface scatter may originate from the grating, slits, mirrors, refractor plates, photomultiplier(s), light baffles, interference filters, dust, and the spectrometer interior surfaces. Essentially all internal surfaces may contribute to scatter. 

Ions and ionized clusters ejected from a surface during ion bombardment are detected with a mass spectrometer. Surface chemical composition and some information on bonding can be extracted from SIMS ion fragment distributions. 

IR spectra were recorded using the KBr disk technique and a Perkin-Elmer 1750 FTIR spectrometer. Surface area and pore volume were determined on a C. Erba Sorptomatic model 1700 apparatus, by means of Nj adsorption. Thermogravimetric (TO) analyses were carried out using a Perkin-Elmer TGS-2 thermobalance with a He-flow of 3dm /h and a heating rate of 600K/h.

The structures of the gold catalysts were observed using a Hitachi H-9000 electron microscope operated at 300 kV. X-ray diffraction (XRD) analysis was made by using a Rad-B system (Rigaku Denki Co.Ltd.). Infrared spectra were taken with a Nicolet 20-SXC spectrometer. For the IR analysis, each sample was mixed with KBr( 2wt.% for magnesia 10 wt.% for titania), and pressed into a thin wafer. Differential thermal analysis (DTA) was made by using a SSC-5200 thermal analyzer (Seiko Denshi Kogyo Co.Ltd.). X-ray photoelectron spectroscopy (XPS) was measured with a SSX-100 spectrometer (Surface Science Laboratories, Inc.).
