    New instruments include industry's first cryogenic grinder (Freezer/Mill) in Spain and energy-dispersive XRF spectrometer

    Event attended by Professor Ramon Tamames, who reflected on role of waste in circular economy


    Madrid, July 2nd 2015. Lafarge Spain has opened an area equipped with state-of-the-art technology for the analysis of alternative fuels at its facilities outside the city of Toledo. This unit is located at the firm's main quality control laboratory, which has been operating for more than 40 years and boasts certification from the National Accreditation Body (ENAC, in its Spanish acronym).


    The incorporation of new instrumental techniques will allow Lafarge to offer maximum guarantees and boost the efficiency of the analytical process. This new area complements the analyses carried out by alternative fuel suppliers and the company itself at the entrance to its factories.


    Among the technology installed, Lafarge now boasts the first cryogenic grinder that exists in Spain in this industry. It is a technique that allows an effective analysis with a single fuel sample (wood, sawdust, tyres and animal meal, for example), by freezing them with liquid nitrogen and reducing the particle size to 100 microns. Another notable feature is the energy-dispersive XRF spectrometer capable of simultaneously analysing 80 chemical elements in both solid and liquid samples or in paste form.


    Lafarge has invested over €300,000 in these instruments and created two new laboratory technician posts, which have been taken on by two women. Isabel Rodriguez Henche, Director of the Lafarge Central Quality Control Laboratory, explains that "the use of alternative fuels makes the company more competitive, as it is less reliant on fossil fuels. At the same time, it benefits the environment and society by giving a safe solution to waste, which otherwise would end up in a landfill site. With this new facility, Lafarge will be offering the very best management guarantees".


    Ramon Tamames reflects on reuse of waste as basis for more sustainable society

    The opening event of this exclusive alternative fuel area had as guest of honour Professor Ramón Tamames, Member of the Club of Rome, Professor of Economic Structure, Jean Monnet Chair of the European Union and Chair of the Royal Academy of Moral and Political Sciences, who in an interesting speech offered his thoughts on the role of waste in the circular economy as the basis for a more sustainable society, a principle with which Lafarge fully identifies.

    According to Professor Tamames "as time goes by, in a world with an ever-growing population, which at the end of this century may well exceed 10 billion, the revaluation of new uses and subsequent applications of any product are fast gaining ground. This is because on a planet where space is increasingly at a premium and resources are finite, the sheer might of reuse becomes all-important".

  • Freezer/Mill used to investigate mummified remains of Queen Nefetari

    Dec 09 2016

    The Freezer/Mill has recently been used in a landmark study to extract DNA from the mummified legs of Queen Nefertari, wife of Ramses II from ancient Egypt.  The aim of the study was to positively identify the remains found in her tomb dating from 3600 years ago.  The procedure was published in the PLOS ONE scientific journal. Please click here to download the article.

  • Remembering Dr. Fernand Claisse

    Jun 08 2016

    The team at SPEX SamplePrep and Katanax are saddened about the passing of Dr. Fernand Claisse. We will never forget his advice and friendship. Please read his bio below to learn more about him.

    Dr. Fernand Claisse was born in Quebec City in 1923.  He obtained his B.Sc. degree in Physics at the Universite Laval in 1947 and the Ph.D. in Physics and Metallurgy in 1957., also at Laval.  From 1947-58, he worked in XRD and XRF for the Department of Mines of Quebec.  In 1958, he rejoined the Universite Laval as a professor until 1984.  He founded the company Claisse Scientifique Corporation in 1972 where he was director of research until 2002. He was the “lucky” user of the first Norelco spectrometer in Canada in 1948 and prepared his first fusion beads in 1955.  He later developed a quantitative theory of the Heterogeneity Effect, the Claisse-Quintin algorithm, the Fluxer V, and in 1982 published with R. Tertain their well known book Principles of Quantitative XRF Analysis.  Since then he has developed specially shaped Pt crucibles to aid the fusion process, other type of fusion machines, a method for the fusion of sulfides, with G.R. Lachance a simply calculation for the tertiary effect in XRF, and a contamination-free manufacturing process for mini-bead fluxes.  In 1995 Lachance and Claisse published Quantitative XRF Analysis.

    Dr. Claisse followed this with the development of a theory of the effect of acidity and atom size on the solubility of oxides in fluxes, the “optimal flux composition”, the first iteration of the Sherman equation, a fusion technique for ferroalloys and metallic powders, and his latest book The Physics and Chemistry of Fusion for XRF Analysis.  For many years he presented annual lectures on fusion techniques at the SUNY summer course and the Denver conference workshops.  Fernand has been teaching with the UWO XRF Course since 1996. He was a great friend, father and teacher and he will be missed by all.
