Ellington and Associates, Inc. provide a complete suite of analytical and interpretative geologic services in support of exploration and production projects all over the world. These services include mineralogy and x-ray diffraction.
Based on our expertise in X-ray analysis methods, we offer mineralogical services to clients in the oil and gas industry, geological, mining and processing, agricultural, and other research organizations.
Our mineralogical team works towards improving the reliability and accuracy of analysis at a high rate of speed. This is accomplished using ''mature'' methods while keeping a close interaction with emerging technologies/methods. The laboratory is equipped with twin Bruker D4s and also multiple Bruker D2s and Terra XRD suitcase models for wellsite use, these instruments combine state-of -the- arts state-of-the-art technology with easy operation. Collecting patterns for qualitative/quantitative phase analysis is one of the major tasks of the D4 ENDEAVOR. In our lab, qualitative mineral phase identification is carried on using JADE processing software. Quantitative mineral abundance determination is achieved through BGMN on the basis of the Rietveld method. We primarily utilize NEWMOD software to preform quantitative analysis on clay minerals.

X-Ray Fluorescence (XRF)
X-Ray Fluorescence (XRF) analyzers can quickly and nondestructively determine the elemental composition of:
Metal and precious metal samples
Rocks, ore, and soil
Painted surfaces, including wood, concrete, plaster, drywall, and other building materials
Plastics, consumer goods
Dust collected on wipe samples
Airborne heavy elements collected on filters
Up to 40 elements may be analyzed simultaneously by measuring the characteristic fluorescence x-rays emitted by a sample. XRF analyzers can quantify elements ranging from sodium (Na - element 11) through uranium (U - element 92).

Mineral Analysis from X-ray Diffraction (XRD)
Our mineralogy team can supply the clients the mineralogy service making use of XRD, FTIR, SEM, and optical mineralogy.
X-ray Diffraction (XRD) analysis
XRD records the diffraction or reflection of a beam of X-rays by solids, including geological samples. The unique arrangement of atoms in each mineral’s crystal structure interacts with the X-ray beam, producing regions of diffraction intensity, or peaks, diagnostic for that mineral.

What is X-ray Diffraction (XRD)? This technology utilizes the diffraction (reflection) of X-rays from the unique arrangement of atoms in a crystal structure. It is generally the fastest and most reliable method to identify and quantify crystalline materials. This method is particularly useful for materials such as clay minerals that have grain sizes too small for microscopic identification.
What can be analyzed by XRD in your lab? Any type of solid material that will produce a diffraction pattern can be analyzed.
How much sample is required? For the optimum results, four grams (4g) of sample are suggested.
