SMI Analytical Laboratory is able to perform various types of chemical analysis, which can be seen on the adjoining schedule. SMI Analytical is dedicated to offering realistic turn-around times and also improved competitiveness. SMI Analytical has combined state-of-the-art X-ray diffraction equipment, a modern sample preparation laboratory and an expert staff to create an excellent clay mineral analysis facility, coupled to a general analytical laboratory. Many engineering, mining and tiling industry companies have made profitable use of the laboratory since it has been established. The laboratory staff has kept customer needs in mind while developing standardized procedures. However, if the service that you need is not listed, you are welcome to contact the laboratory and arrange to have an analytical scheme specially tailored to meet your needs. The laboratory emphasizes clay mineral analyses but is capable of most chemical analysis.

X-RAY DIFFRACTION LABORATORY EQUIPMENT

The focus of the laboratory is a microprocessor controlled diffractometer. X-ray diffraction is a non-destructive method for determining the molecular or atomic make up of an unknown compound or mixture. It has become the most widely used investigative technique in mineralogy. Both reflection and transmission methods are available. Careful study of diffraction traces yields a vast amount of information. The qualitative and quantitative mineral composition of a sample can be estimated, particular polytypes can be identified and the crystalinity of mineral species can be assessed. One should bear in mind, however, that minor phases below a detection limit of approximately 1-2 per cent are not accurately revealed.

XRD is the most powerful tool used in examining clay materials. The major clay-mineral groups and often the particular phyllosilicate species within these groups can easily be identified, even in complex mixtures. The study of diffraction patterns of orientated and random clay preparations (< 2 micron), combined with auxiliary treatments, often yields general information on the chemical composition of the major clay components present.

X-ray powder diffraction (XRPD) has many applications in the pharmaceutical industry - from drug discovery, pre-formulation and formulation, through to manufacturing and quality assurance. In all of these areas, XRPD is used to determine the crystallographic constitution of the sample from which the physical properties of an active pharmaceutical ingredient or an excipient can be derived. In contrast to other commonly used techniques, X-ray analysis is non-destructive.

X-ray diffraction data most commonly used and asked for:

  • Weight% and volume% mineralogy.
  • Calculated grain densities and Vshale.
  • Multiple-size fraction clay mineral studies.
  • Mixed-layer clay characterization.
  • Drilling, completion and stimulation recommendations.
  • Clastic and carbonate diagenesis.
  • Shale diagenesis and thermal maturation.
  • Analysis of primary siliceous sediments.
  • Wireline log interpretation and calibration.
  • Volume percent mineralogy/density calculations.
  • Reservoir quality and sensitivity.
  • Completion and stimulation design.
  • Produced solids and scale/corrosion products.
  • Drilling mud and frac sand analyses.
  • Clay and zeolite mineralogy of soils.
  • Analysis of synthetic and natural liner materials.
  • Ore mineralogy and hydrothermal deposits.
  • Mineral impurities in raw materials used in manufacturing.
  • Mineral impurities in coals.

APPLICATIONS OF CLAY MINERAL ANALYSIS

Most engineering companies ask whether a soil sample contains expandable clays and if so how much? Is the abundance of expandable clay in a soil profile constant or variable? Will the company experience more foundation problems related to clays in one area than another? Which soils differ from each other, and how? The laboratory has helped companies answer these questions and has provided information which improved their ability to make accurate cost estimates and better bids. Corporations in the tile industry have been interested in clay mineralogy and the clay minerals routinely analysed for are:

  • Illite and Mica
  • Chlorite
  • Kaolinite
  • Smectite
  • Mixed-Layer Illite / Smectite
  • Mixed-Layer Chlorite/Smectite
  • All clay phases identified and quantified

R & D PROGRAMS FOR CLIENTS

SMI Analytical has adopted a dual R & D perspective, i.e. Self-generating R & D programs which are conducted on a commercial feasibility basis. However, the option of being sub-contracted out can be negotiated.

Some of SMI Analytical's past, present and future projects involved/will involve:

  • Photocatalysis
  • Plant Hormones & Nutrients
  • Hydroponic Analysis & Assessment
  • Portable GC Analysis for Smell Identification
  • Bio–remediation
  • On–line Analysis
  • Quality Control
  • Industrial product formulation
  • Cosmetic industry product formulation
  • Reverse engineering

SOLUTION MANAGEMENT

Dedicated professionals are available for the resolution of industrial and agricultural situations where existing practices and technologies have become either ineffective, inadequate or when such are non-existent.

For Example:
Escalating protocols for the generation of clean air and water are restricting industry and agriculture to manufacture or produce using more efficient and cleaner processes. i.e. Penalties for the discharge of bio-hazardous materials are escalating on a continuous basis.

The above produce a synergistic effect and are all related. SMI Analytical’s activities are conducted in modern, sophisticated laboratories, using test methods, techniques and quality management programs that comply with recognized international practices and standards. The laboratory staff is prepared to help companies work on projects and solve problems related to these and other applications.

SMI Analytical is based in Centurion, Pretoria, and has easy access to major arterial networks and airports allowing for rapid communications between clients and source.
