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:

 *     Netzsch 404 Differential Scanning Calorimeterfor quantitative Heat Capacity, Transition Enthalpy, Glass Transition, and Crystallinity from room temperature to 1400° C

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 uses a Superconducting Quantum Interference Device (SQUID) Magnetometer to measure the magnetic properties of samples. 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 sensitvity 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.
• 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.
• TJA IRIS Inductively Coupled Plasma ICP Spectrometer for elemental analysis.
• 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.
• Two MicroMeritics BET Porosimiters for surface area, pore volume, and pore size distribution measurements.
• AccuPyc 1330 Pycnometer, for very precise density measurements of small solid samples.

We can measure samples for other Universities and companies. Fees depend on the requirements of the test.

Recharge Rates for all instruments located at the TEMPO facility.

Instruments here 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:

All people working in the chemistry lab are required to follow good practice and to have already attended the UCSB EH&S Laboratory Safety Training.
