JEOL JSM-6490LV Scanning Electron Microscope
The scanning electron microscope is a high resolution imaging and microanalytical platform. It produces a magnified image of a sample by scanning a focused electron beam across the surface of a sample and observing various signals produced when electrons interact with the sample. Images with magnifications from 8-300,000x can be collected with an ultimate resolution of 3 nm.
Almost any solid material can be observed using the SEM. Because of the variable pressure abilities of the SEM it is possible to observe insulating materials directly without the need for a conductive coating in the LV mode. It is also possible to observe biological materials without the need for extensive sample preparation. More information can be found here.

- The advance capabilities include but not limited to z-stack imaging for optical slicing 3-D scan, bleaching for fluorescence recovery after photo-bleaching (FRAP) and tile scan (large area scan).
- The microscope is also capable of brightfield imaging and differential interference contrast imaging.
- User-friendly Zen software allows us to perform complex tasks in a very simple manner.

Phillips X'pert MPD Powder X-Ray Diffractometer (Powder XRD)
The powder x-ray diffractometer is used to determine the crystalline structure of materials. By measuring the amount of an incident x-ray beam that is diffracted through the sample at a range of incident angles it is possible to identify the material being examined by comparing these angles to those from known materials.
It is used primarily for phase identification of crystalline powders. Powerful Jade software allows us to quantify the relative proportions of phases in a polyphase material or determine unit cell parameters of specific phases via Rietveld refinement. More information can be found here.
Rigaku Rapid II Single Crystal X-Ray Diffractometer (Single Crystal XRD)
The single crystal x-ray diffractometer allows for the precise determination of the atomic structure of crystalline materials. By placing a single crystal of a material in an intense monochromatic x-ray beam, diffraction patterns can be produced. A series of diffraction patterns are collected as the crystal is rotated 3-D in the x-ray beam.
By analyzing these diffraction patterns it is possible to determine the precise crystalline structure (position of each atom, bond lengths and angles between atoms). This information is very useful when developing new compounds or investigating specific properties of known compounds. More information can be found here.
Rigaku NEX CG X-Ray Fluorescence Spectrometer (XRF)
The x-ray fluorescence spectrometer is typically used to determine the elemental composition of bulk materials (rocks, ores, metals, concrete, etc). By exciting a sample with an intense x-ray beam, the sample will emit x-rays with energies characteristic of the elements in the sample. By measuring the relative intensity of the various x-ray energies emitted from the sample, it is possible to precisely determine the elemental composition of the sample.
It can also be used to measure elements in liquid samples (oil and aqueous samples) although the detection limits for liquid analysis are higher. The instrument has been acquired by several professors in collaboration with RIL in 2017. More information can be found here.

Caliper IVIS Spectrum In-Vivo Imaging System
The in-vivo imaging system allows non-invasive longitudinal monitoring of disease progression, cell trafficking and gene expression patterns in living animals (for example, cancer in mouse) using fluorescence irradiation. It is equipped with a variable range excitation filter and emission filter. It can measure fluorescence emission in response to the incident irradiation or bioluminescence emission from sample. More information can be found here.
Thermo ICS-1100 Ion Chromatograph (IC)
The ion chromatograph separates ions and polar molecules in liquid sample based on their affinity to the ion exchange material in a column and measure abundance of each ion by a conductivity detector. More information can be found here.
SEE Co MS6 Mossbauer Spectrometer*
The Mossbauer spectrometer can measure oxidation state or coordination state of select metal (specific to each radioactive source) in sample using gamma ray emitted from the source. It currently has a cobalt 57 source and therefore can analyze iron. More information can be found here.
