Olympus Australia announces the launch of two new portable X-ray fluorescence analysers designed to provide fast, non-destructive qualitative and quantitative characterisation of materials. Olympus is a world-leading manufacturer of optical, electronic and precision engineering products and continues to be at the forefront of the development of portable X-ray fluorescence analysis technology since the 1960s.

Geochemical analysis of minerals and non-destructive testing (NDT) of manufactured materials by X-ray fluorescence (XRF) is a crucial tool in many industries. XRF technology can be used for applications ranging from measuring the concentrations of elements in soil or rock samples, or identifying the grade of stainless steel in a section of pipeline, to authenticating the composition of paint in an artwork or detecting the presence of toxic chemicals in toys.

XRFs can be used for detection, identification and analysis of elements at a range of concentrations. 

Operators of handheld XRF analysers may be exposed to radiation to. However, Olympus XRF analysers are designed to minimise the ‘equivalent radiation dose’ to which a technician may be exposed. 

An XRF analyser uses a controlled beam of radiation to excite the electrons in a sample causing the elements to ‘fluoresce’. Each element fluoresces at a specific energy level, which can be identified as a characteristic peak. A higher peak indicates a greater concentration of an element.

Andrew Taylor, Regional Sales Manager with Olympus, announced that the company had released two new handheld XRF models. While the Delta Premium Plus is aimed at the mineral exploration and mining sector, the Delta Professional has been developed for the alloy and NDT sectors, especially companies conducting analysis of manufactured and scrap materials such as stainless steel and a wide range of other alloy types.

The Premium Plus XRF analyser is most commonly used by field geologists to determine elemental concentrations in a particular soil, rock or ore sample. Typically carried out by mining companies in remote areas, this type of work can now be executed onsite, thereby minimising the number of samples that need to be sent to a laboratory for analysis, saving both time and money.

When a Delta Premium is calibrated with ‘Geochem’ mode, it looks for specific elements and can accurately measure concentrations from parts per million (PPM) up to percentages. It can detect elements in the periodic table ranging from Magnesium to Uranium. Used on location for immediate results, the Premium can help determine the next course of action, when time is a critical factor or materials cannot be transported, damaged, or altered.

Some models in the Delta analyser range feature the Window Guard system, an economical, easy to mount and remove accessory designed to protect the instrument's sensitive components from damage by sharp objects, dirt and debris. The Window Guard can minimise costly repair bills and downtime, especially when testing metal turnings, shavings and protruding components. 

Unlike early XRF analysers that were large, floor-mounted power-intensive and expensive devices, XRF technology has advanced to a level where the user now has all the advantages of portability, small size and low cost.
