Varian 240FS & GTA 120 Furnace

This "fast-sequential" Atomic Absorption Spectrophotometer is for the elemental analysis of a variety of samples digested into aqueous solutions

Bruker-D8 X-Ray Diffractometer

This new X-ray diffraction instrument allows analysis of any type of solid material. The X-ray diffraction is a very common tool in the analysis of the amorphous nature of solid state battery electrolyte materials.

Electrochemical Workstation Zahner IM6

BAS C-1B Cell Stand

Equipped with a programmable Potentiostat, a pair of high precision amplifiers for current and potential, a flexible frequency generator/analyzer and four slots for additional input and output modules are designed for nearly all measurement situations in the electrochemistry lab. Specially designed for spectrum analysis in the electrochemical field, the modular hardware concept of the IM6 allows you to configure the IM6 for applications far beyond impedance spectroscopy.

Main methods

• impedance spectroscopy
• simulation & fitting
• cyclic voltammetry
• automatic series measurements
• polarization curves
• multi cell voltammetry
• electrochemical noise analysis
• arbitrary current/potential/time acquisition
• capacity/potential measurements
• high current applications
• transient recording
• acquisition of time domain data
• integrated CAD and word processing software and many other acquisition & analysis methods

Cyclic voltammetry is a versatile electroanalytical technique for the study of electroactive species. CV consists of linearly cycling the potential of an electrode immersed in an unstirred solution while measuring the resulting current. Thus, a voltammogram is a display of current versus potential. The most useful aspect of this technique is its application to the qualitative diagnosis of electrode reactions.

The Cell Stand features magnetic stirring and selectable gas purge rate for the sample. The gas control provides for blanketing the sample when active purging is not occurring. The magnetic stirrer controls mass transport to the electrode surface and mixing for titrations. The lift arm with detachable cell top allows removal and replacement of the cell vial. The cell is enclosed in a Faraday Cage to minimize electrical interference.

Energy Dispersive- X-Ray Fluorescence (ED-XRF)

Thermo Electron Corp. (2005)

Quan-X EC

The new ED-XRF instrument for the elemental analysis of a variety of samples particularly for high concentrations and thus complements the ICP-MS which must use very dilute solutions. Sample grinding and pellet press ancillary equipment were also obtained.

Perkin Elmer Spectrum One Fourier Transform Infrared Spectrophotometer (FT-IR)

The "diamond anvil" ATR attachment allows powdered solids, films and liquids to be easily analyzed directly.

 Agilent Technologies

7890A GC
5975C MSD

A primary workhorse in our analytical arsenal is the gas chromatograph/mass spectrometer (GC/MS), giving resolution of a wide variety of mixtures as well as identification of each compound. This system is fully programmable, so all temperature and pressure sequences at every point in the chromatographic process can be automated.

Varian Instruments (2005)

The new instrument represents the "state-of-the-art" for the elemental analysis of a variety of samples particularly for low concentrations and thus complements the AA, which is suited for more concentrated solutions.

Liquid Chromatography (High Pressure)

Waters Breeze HPLC
Waters 1515 Pump
Waters 410 Detector
Waters 440 Detector

To achieve satisfactory susceptibility of compounds to our analytical techniques, it has become necessary that we implement a liquid chromatography system with capabilities comparable to the gas chromatograph. This system currently consists of a Waters 1515 HPLC pump, Waters 410 Differential Refractometer and a Waters 440 Absorbance Detector.

The microwave reactor allows a variety of samples to be digested into solution for analysis of elements by the ICP-MS. It also allows many synthesis reactions to be conducted with much shorter times and higher yields than conventional heating.

Bruker 400 MHz Advance III NMR Spectrometer with multinuclear probe and superconducting magnet 

Bruker Top Spin 2 Analytical Software

The NMR Lab's instrument is capable of multinuclear operation. In addition to classic proton NMR, we are able to effect such analyses as heteronuclear correlation spectroscopy and NMR of a wide variety of elements such as phosphorous and vanadium, by virtue of the fully tunable multinuclear probe.

The magnet is a 9A Tesla superconducting electromagnet housed in liquid helium, and that is housed in liquid nitrogen. It has an "active shielding" so that it does not erase credit cards, etc. of instrument users.

HP 8453 UV-Visible Diode Array Spectrophotometer

Dell Workstation

HP UV-Visible ChemStation Analytical Software

Our analytical spectroscopic range is enhanced by the addition of a Hewlett Packard ultraviolet/visible spectrometer. The user interface was updated with a Dell computer. Also HP company is now the Agilent Technologies.
