Techniques

Brunauer- Emmett-Teller (BET) theory explains the physical adsorption of gas molecules onto a solid surface and serves as the basis for an important analytical technique – the measurement of the specific surface area and pore structure of materials. Utilising nitrogen or krypton gas adsorption the specific surface area is precisely measured as a function of […]

A scanning electron microscope (SEM) produces images of a sample by scanning over it with a high energy beam of electrons which can be focused to a spot approximately 1 nanometer in diameter, allowing resolution limits down to about 10 nm. Here at Microanalysis we run two scanning electron microscopes, the JEOL 5800 LV and […]

XRD offers an incredibly useful tool in determining – phase composition across a whole range of applications. Our XRD capabilities are driven by a Philips X’pert x-ray diffractometer coupled with the Bruker EVA 3.1 software and ICDD PDF4 database for phase identification. We offer qualitative, semi-quantitative and fully quantitative phase analysis to suit your specific […]

Our Nikon SMZ18 has the highest zoom ratio (25:1) of any optical microscope on the market, Microanalysis can now image in the macro and micro simultaneously on the one instrument. A resolution of just a couple of microns coupled with high brightness and contrast make this microscope ideal for complimentary imaging with our state-of-the-art electron […]

Microanalysis Australia has been assisting clients accurately determine their bulk cargo moisture limits for a decade, utilising  TML flow table and protector-fagerberg techniques. Transportable Moisture Limit determination is a delicate science, which results in a report without which a ship containing bulk cargo is unable to leave port. The TML value represents a ‘safe’ moisture […]

Microanalysis has recently acquired an Agilent 7890 GC-MS (Gas Chromatogram – Mass Spectrometer) for its new premises at East Perth. A GC-MS is composed of three basics building blocks: A means of introducing the sample via an injection port. The separation of mixtures of compounds by partitioning them between a gas phase (typically helium) and […]

Laser interferometry is a particularly useful analysis, allowing for non-destructive high resolution imaging and surface topography mapping that is suitable for a wide range of samples. With scan areas up to 10cm x 10cm, surface resolutions down to 1µm, a maximum depth of field of 24mm and an axial resolution as low as 0.008µm the […]

The instrument used is a Malvern Instruments Mastersizer MS2000. Any material present in the sample greater than  500 µm in diameter has to be manually sieved out of the sample prior to analysis by laser diffraction.  This is conducted because of the limitation of the instrument to representatively suspend particles larger than this size, especially […]

The instrument used is a Micromeritics Sedigraph 5100. For dry powders a representative 10-20g subsample is taken and dispersed in approximately 75mL of 1000ppm sodium hexametaphosphate (Calgon) using a Cole-Palmer 8851 (or equivalent) ultrasonic bath for 15 minutes. Some powders may require the addition of a wetting agent to enable full dispersion. In this instance, […]

Particle Counting is useful for finding the particle size distribution and concentration of clean liquids such as waters, diesels and other solutions. The instrument used is a HIAC ROYCO Liquid Particle Counting System 9703 and utilises light extinction to count the number and size of each particle individually. The instruments can be fitted with a […]

Our Micromeritics Multypc is an automated gas pycnometer capable of determining absolute density of a wide range of solids to near reference value accuracy following ASTM D4892. Using ideal gases such as helium, and employing Charles’ Gas Law, a reference volume can be pressurised to a known value before allowing this charge to pass into […]

Microanalysis has a wide range of calibrated Endecott sieve sizes, from 32 µm to 9.5mm. We offer wet and dry sieving services, and are able to combine sieving data with data from other sizing techniques such as Sedigraph and laser diffraction.

Our micro-riffler allows us to quickly, easily and representatively subsample your samples for analysis.

Our pH meter, conductivity probe, dissolved oxygen meter and chlorine and fluorine selective electrodes allow us to measure fast and accurate acidity, fluoride and chloride content.…

Our Brookfield Viscometer is equipped with a range of spindles which can be calibrated between 10 cP to 5000 cP.

Our Carbolite tube furnace has been upgraded with the latest temperature control software to allow temperature control between ambient and 1250°C to better than ± 1 %. Contolled atmosphere purge is available for both anaerobic and aerobic oxidation experiments.

Our IKA KS4000i and Ratek OM11 temperature controlled orbital shakers are primarily home to samples for dissolution testing and corrosivity testing, which require controlled agitation and temperature.

Moisture content is conducted using a Kern MS1 moisture balance. The analysis can be performed at 50°C to ~200°C as required. The sample is heated until the weight change is less than 0.01%.
