360 for transmittance and absorbance infrared spectroscopy. It is capable of scanning
linear frequency range of 4000 to 400 cm-1 with a resolution of 1 cm-1.
The
Avatar unit is equipped with a Thermo Nicolet SMART OMNI-Sampler accessory to
perform Horizontal Attenuated Total Reflectance (HATR) spectroscopy. The rugged
germanium crystal, with a range of 4000 to 675 cm-1, can handle not only liquids
and pliable solids, but also "point-to-point" contact of difficult samples,
such as single polymer beads, hard rigid polymers, and coatings on glass substrates.
(Description) (Examples)
The
micro-analytical equipment is based on a JEOL JSM-35C, scanning electron microscope/microprobe.
It is capable of producing a 40 keV electron beam with a resolution of 70 Angstroms.
The
energy dispersive x-ray spectrometer is an EVEX SIUTW detector with a hydrocarbon
window. It is capable of detecting elements as light as carbon to as heavy as
uranium. Standardless Quantitative (SD) analysis is performed using advanced software
in the EVEX Microanalysis Computer System. Typical x-ray energy resolution is
about 2.5% of the peak energy, approximately 150 eV for a Mn Kα peak at
5890 eV. (Description)
The
ion chromatography equipment is based on Metrohm-Peak's 761 Compact IC. This unit,
while currently set up for suppressed anion chromatography, can be set up for
HPLC as well as cation chromatrography.
The
unit features a built-in injection valve, a low-pulsation serial dual-piston pump,
a pulsation dampener, variable flow range from 0.2 to 2.5 mL/min, and a maximum
working pressure of 5,000 psi. The insulated column compartment provides temperature-stabilization
better than 0.01°C for the conductivity detector.
