TEMPO Facility : Thermal, Electronic, Elemental, Magnetic, Porosity, and Optical Facility |
Formerly called the Chemistry Facility
The MRL TEMPO Laboratory has advanced instrumentation
for the characterization of materials and chemical samples. We offer an extremely wide range of
instrumentation for Thermal, Electronic/Elemental, Magnetic, Porosity, and Optical measurements.
This instrumentation is available to users from UCSB, other Universities, and Industry.
Training is available. We are now offering a testing service.
We have instrumentation for measuring the:
- Thermal Properties of Samples
- TGA/DTA
- DSC
- High Temp XRD
- PPMS
- Electronic & Magnetic Properties of Samples
- PPMS
- SQUID
- TGA
- Elemental, Phase, & Evolved Gas Composition of Samples
- ICP
- XRD
- MS Accessory for TGA
- Optical Properties of Samples
- UV-Vis-NIR Spectrometer
- Fluorimeter
- Olympus BX41 Fluorescence Microscope
- Porosity, Surface Area, & Density of Samples
- TriStar BET Porosimeter
- Pycnometer
The Instruments and What They Can Do:
-
Quantum Design Physical Properties Measurement System PPMS. This measures
Resistivity, AC Transport (Hall Coefficient, I-V Curve, Resistivity & Critical Current for superconductors),
and Heat Capacity. All for small samples under controlled magnetic field and temperature. The magnetic field
may be programmed anywhere from 0 to +/- 7 Tesla and the sample's temperature can be programmed from 1.9 to 400 K.
-
Quantum Design MPMS 5XL SQUID Magnetometer
to measure the magnetic moment of a sample, from this the magnetization and magnetic susceptibility are
determined. It is extremely sensitive for all kinds of AC and DC magnetic measurements. Applications
include measurements of small quantities of paramagnetic ions, characterization of all kinds of magnetic
materials, and quantitative determination of the number of unpaired electrons in samples. Data can be
collected between H = 0 to +/- 5 Tesla and between 1.7 and 400K. The sensitivity is in the range of 10-9 emu.
-
Mettler 851e TG coupled to a Pfeiffer ThermoStar Mass Spectrometer
TGA-MS for thermo gravimetric analysis
with an option for evolved gas analysis. This same instrument can measure the Curie temperature for materials
above room temperature.
-
The Netzsch Differential Scanning Calorimeter DSC is designed to quantitatively measure
the energy absorbed or released by samples as they are heated and to measure the temperature at which any changes occur.
-
Bruker D8 Theta-Theta XRD outfitted
with an Anton Parr high temperature stage for the measurement of
X-Ray Diffraction patterns of powders, thin films, and foils to
1500°C. Scans are very fast. Sample temperature may be controlled from room temperature
to 1500°C.
-
Thermo iCAP 6300 Inductively Coupled Plasma ICP Spectrometer for elemental analysis down to 10 PPB.
-
Shimadzu UV3600 UV-Nir-NIR Spectrometer with an Integrating Sphere for Diffuse Reflectance,
Specular Reflectance, Transmission and Absorption measurements of powder, thin film, and liquid samples in the range of 220 to 2600 nm.
-
Perkin Elmer LS 55 Luminescence Spectrometer. This is a very versatile instrument that allows
measurement of fluorescence, phosphorescence, chemiluminescence, or bioluminescence of
liquid, solid, powder, or thin film sample. The sample is illuminated in the wavelength
range of 200 to 800 nm and the emission spectra recorded from 200 to 900 nm.
-
MicroMeritics TriStar Porosimeter
for surface area, pore volume, and pore size distribution measurements.
- The Olympus BX41 Fluorescence Microscope
illuminates samples from above as well as from below as in a conventional microscope.
Excitation in the ultraviolet (330-385 nm), blue (460-490 nm), green (510-550 nm) and
full spectrum light are available.
- Pycnometer
for density measurements.
Recharge Rates for all instruments
located at the TEMPO facility.
All instruments are available for responsible
users to test their own samples. Training is offered quarterly for the more complex
instruments and users may self train on the other instruments any time. There are specific
insurance and liability requirements for off-campus facility users. They are described at this link:
http://www.mrl.ucsb.edu/mrl/centralfacilities/nonUCSB_recharge.html
All people working in the TEMPO lab are required
to follow good practice and to have already attended the UCSB EH&S
Laboratory Safety Training.
