Ultra Performance Packages for Oil and Gas and Mineral Exploration
Thermo Fisher Scientific Inc (USA), world specialists in serving science, recently introduced the Thermo Scientific Ultra Performance Packages for improved light element analysis. To achieve a higher level of performance, the packages combine a portable X-ray fluorescence (FPXRF) analyser with a larger silicon drift detector (SDD), unique, field-portable sample preparation tools, and a helium (He) purge option. This combination of portable technologies is a breakthrough for determining light element concentrations in field-prepared mineral samples. This capability is increasingly important for oil and gas and industrial mineral exploration as light element analyses is used to infer mineralogy, which can help to determine physical properties of rocks, such as permeability, porosity and oil/gas production capability.
Currently, more than 3,000 Thermo Scientific portable XRF analysers are used across the global mining industry for mineral exploration, from gold and copper porphyry deposits to nickel laterites, rare earth and platinum group elements. Portable instruments are an integral part of next-generation mining, putting the power and precision of a laboratory instrument in the hands of field personnel to accelerate discovery and contribute to increased profitability.
“Until now, sample presentation limitations have made the geochemical analysis of light elements using field-portable XRF instrumentation unreliable,” said Jon Culbertson, vertical market director of mining and exploration for Thermo Scientific Portable Analytical Instruments. “By combining multiple technologies in a single package, we’re giving
our customers next-gen mining innovation that can improve exploration and, ultimately, accelerate the entire mining process.”
Available Ultra Performance Packages can include: A Thermo Scientific XL3t Ultra XRF analyser that is purpose-built for mining and exploration analyses, including a larger silicon drift detector for higher resolution and superior light element analyses; Field-portable sample preparation tools that can create powders out of larger rocks and samples to optimise particle distribution and can deliver pressed pellet samples with the correct presentation and depth for optimal FPXRF analysis; and A He purge system to displace air in the gaps between the sample and the detector that can make it difficult to “see” light elements.
Reader Reply Card No 71 New Distributor for OBLF Product Line
Underlining the long standing relationship between the two companies, PANalytical (Netherlands) and OBLF jointly announce that a formal agreement has been signed for the exclusive distribution of OBLF’s optical emission spectrometers by PANalytical in Finland, Sweden, Norway, Denmark, the Netherlands, Belgium, Luxemburg, United Kingdom, Ireland, France, Spain, Portugal, Italy, South Africa, USA, Canada and Brazil.
PANalytical X-ray fluorescence (XRF) spectrometers and OBLF optical emission spectrometers (OES) perform complementary roles in the analysis of solid metals. When deployed together, XRF and OES allow for the measurement of dozens of elements over concentration ranges from sub-ppm to 100% within seconds. This combination of speed and versatility makes XRF and OES ideal for laboratories where metals analysis is a primary task. In addition to numerous automated laboratory installations featuring both XRF and OES ‘stand-alone’ instruments, the co-operation between the companies has already resulted in the development of TEAMworks, a fully automated laboratory system combining OES, XRF and robotic sample handling. For these combined systems, PANalytical has taken full responsibility for installation, training, maintenance, and application support for both its own X-ray spectrometers and OBLF’s optical emission spectrometers.
“The combination of OBLF’s exceptional product line with PANalytical’s unparalleled customer support promises an unsurpassed customer experience with optical emission spectrometry” says Dr. Peter van Velzen, CEO of PANalytical. Mr. Bringfried Overkamp, owner and CEO of OBLF, adds that “he is delighted that this experience is now available to a greater part of the world”.
Both companies share a philosophy of quality first, and both operate a quality management system in accordance with ISO 9001¬2008. PANalytical, in agreement with OBLF, is committed to serving the XRF and OES needs of the metals analysis laboratories in the countries where OBLF is currently not represented.

Automated Humidity Control for Calibration Gas Generator
Kin-Tek (USA) has added an Automated Humidity Control option to the FlexStream Modular Gas Standards Generating System. Adding humidity allows simulation of real sample streams.
The FlexStream System dilutes the emission from permeation or diffusion tubes with an inert gas, typically nitrogen or zero air, to create trace concentration – ppm, ppb and pptr – gas mixtures. An internal microprocessor sets the operating mode and adjusts dilution flow to achieve the required concentrations.
The FlexStream HG fits into the system as the end module. A portion of the inert dilution gas is saturated with water and mixed with dry, trace component carrying gas to form the humidified mixture. Humidity is adjusted by varying the ratio of wet to dry gas. Typically, values from 20% RH to about 90% RH can be achieved.
The system can also be controlled remotely by a PC or process computer using Modbus connectivity. Reader Reply Card No 210
