The X-ray Fluorescence (XRF)

The X-ray Fluorescence (XRF) spectrometer is located in the Grant Institute of Earth Science at the University of Edinburgh. The facility primarily supports research programmes within the School of Geo Sciences but also provides an analytical service to the wider earth and environmental science community.

The instrument may be used for qualitative or quantitative analysis of geological materials. A quantitative whole-rock analysis may be obtained for most elements heavier than oxygen, with abundances in the range 1 ppm to 100 wt.%, depending on instrument sensitivity at the wavelength of the analytical line and availability of calibration standards.

The facility consists of an instrument laboratory and dedicated sample preparation laboratories, supported by sawing, crushing, and grinding facilities.

Sample Requirements

Powders used for XRF analysis must be very finely ground using either tungsten carbide or agate grinding apparatus. Powders that feel gritty are generally unsuitable for analysis, and such powders must be reground before being submitted for analysis. Normally at least 10g of powder should be available for major- and trace-element analysis.

Major-element concentrations are measured on 40mm-diameter fused glass discs. About 0.9g of sample powder is mixed with a borate flux using a 5:1 (flux:sample) dilution and fused in Pt-5%Au crucibles at 1100°C.
      Please note the following important points:A 40mm-diameter glass disc cannot be made using less than 0.8g of powder.
Samples containing sulphides or more than 100ppm of As, Sb, Pb or Sn must not be fused in Pt crucibles.
Samples containing free carbon or organic material must be pre-ignited at 400°C in porcelain crucibles prior to fusion.

         Trace-element concentrations are measured on pressed powder pellets. About 8g of powder is required to make a 40mm-diameter pellet but it is also possible to make 30mm-diameter pellets (using 4g of powder) and 13mm-diameter pellets (using 1g of powder) for some analytical applications. Gritty powders do not make stable pellets and the pellets will produce poor analyses.
       Note: Pellets backed with pressed boric acid powder are not suitable for analysis in the current instrument.

iCAP 6000 Series ICP Emission Spectrometer

Thermo Scientific - Scientific Instruments

• 

1          CAMBRIDGE, UK (February 4, 2010) – Thermo Fisher Scientific Inc., the world leader in serving science, today announced that Bormioli Rocco, a producer of glass and plastic pharmaceutical packaging, glass containers for perfumery and foodstuffs and glass tableware, has purchased and deployed the 2000th Thermo Scientific iCAP 6000 Series inductively coupled plasma (ICP) emission spectrometer. The company relies on ICP emission spectrometry to ensure that alkaline metal concentrations in their glass materials conform to current European legislation. Since deployment, Bormioli Rocco has increased lab productivity while lowering its costs.

2          Bormioli Rocco selected the Thermo Scientific iCAP 6300 Duo ICP for its flexibility and exceptional performance capabilities, which ensure accurate, precise analytical results and higher productivity. Also important was the small footprint of the system, which makes it easier to transport and install, an important benefit for modern labs where bench space is increasingly limited.

3          Gareth Jones, product group director, Trace Elemental Analysis, Thermo Fisher Scientific, comments: “Our iCAP 6000 Series delivers outstanding performance, ease-of-use and low cost-of-ownership, all in a uniquely compact instrument. These benefits are possible because of the expertise, hard work and commitment that goes into producing such a superior analytical solution. Achieving the 2000th-order milestone clearly demonstrates that customer’s value the instrument’s quality and reliability."

4          The iCAP 6300 Duo ICP spectrometer features dedicated radial and duo plasma viewing options for enhanced application flexibility. The instrument’s high-efficiency optical design facilitates simultaneous analysis of 66 elements, providing detection limits at less than 1ppb. In addition, the system offers powerful full-frame technology for fingerprinting and retrospective analysis, as well as unique EMT torch technology for routine maintenance operations without switching off the plasma.

Laboratories use the iCAP 6000 Series ICP emission spectrometers to detect and measure low levels of toxic elements and a diverse range of pollutant elements in the global environmental, metallurgical, petrochemical, food and pharmaceutical industries.

Microscope Wins R&D 100 Award Thermo

2        Thermo Fisher Scientific Inc., the world leader in serving science, today announced that its Thermo Scientific Nicolet iN10 MX FT-IR microscope has been selected as an R&D 100 award winner by an independent judging panel and editors of R&D Magazine. Recognized as one of the year’s 100 most technologically significant products introduced into the marketplace, the Nicolet™ iN™10 MX stood out among the other entries because of its outstanding capability to efficiently address the main challenges associated with infrared microscopy, namely system integration, complexity, accuracy and speed. The novel microscope offers high speed imaging and increased accuracy while the built-in sampling and analytical procedures ensure ease-of-use.

3        Infrared microscopes currently require attachment to an external infrared spectrometer, with the spectrometer’s excitation energy redirected through the microscope. The Nicolet iN10 MX uniquely incorporates all of the spectrometer’s infrared optics in a single, integrated system, providing much higher optical efficiency for improved sampling, enabling use of a room temperature infrared detector and reducing bench space.

4        In addition, the Nicolet iN10 MX eliminates the need for specialist training in microscopy or spectroscopy as, for the first time, several assisted sampling and analytical procedures are built into the microscope’s optical operation and software. The pioneering FT-IR microscope enables the analysis of samples as small as three to four microns, allowing for single point analyses as well as mapping or chemical imaging analyses. Conventional infrared microscopes can only analyze samples that are a minimum of ten microns.

5        The Nicolet iN10 MX surpasses its competitors by facilitating the acquisition of chemical maps at a considerably faster rate. With the standard detector configuration, it is possible to map a 1.2 x 1.2 mm area in less than 4.5 minutes, while with an additional imaging detector, the system can scan the same area in only 20 seconds. This is more than ten times the speed of conventional image mapping techniques.

6        "We are delighted to have been awarded the R&D 100 Award. It is not only a recognition by important people close to the industry, but also a statement relative to the iN10 MX state-of-the-art technology and its ability to meet technical challenges of modern day process monitoring applications," said Mike Jost, vice president molecular spectroscopy at Thermo Fisher Scientific.
