Analytical Methods Poster Prize: ICAVS-7 Conference, Kobe, Japan

Analytical Methods Poster Prize: ICAVS-7 Conference, Kobe, Japan

We are please to announce that the Analytical Methods Poster Prize from the recent ICAVS-7 Conference held in August 2013 in Kobe, Japan has been awarded to Satoko Tanimoto.

Satoko has just finished working at Imperial College London as the AHRC/ESPRC Science and Heritage programme post-doctoral fellow from October 2010. She previously completed a 3 year Andrew W. Mellon Fellowship at the Department of Conservation and Scientific Research, British Museum, where she worked on a number of projects, using a range of analytical techniques, including the technical study of a large set of Italian Renaissance drawings that were included in the exhibition, Fra Angelico to Leonardo: Italian Renaissance Drawings, which took place from April to July 2010. This was a collaborative project with the Gabinetto Disegno e Stampe degli Uffizi.
 
Satoko has a first degree from the Kobe Pharmaceutical University (Chemistry and Pharmacy/Pharmacology) in Japan and a MSc in Environmental Sciences and Management from the University of San Francisco. She also spent a year as an intern at the Getty Conservation Institute, before completing her PhD research at the Institute of Archaeology, University College London. During her PhD, Satoko also spent several extended periods working in the Science Section at the Victoria and Albert Museum, as a tutor in the Conservation Department at the City and Guilds Art School and with the Courtauld Institute of Art on wall paintings in Ahhichatragarh Fort/Nagaur Fort, India.

Satoko is looking forward to pass on her experience and knowledge to MA students at the Conservation of Wall Paintings Department, the Courtauld Institute of Art in her next post.

Satoko’s recent AHRC/EPSRC Science and Heritage project at the Imperial College was to explore the application of micro ATR-FTIR spectroscopic imaging to cultural heritage samples from the collaborative partners, The National Gallery London and the British Museum, and to develop aspects of the methodology. 

Characterisation of the materials of cultural heritage collections is vital in understanding how they were made and used, their conservation history, origin and mechanisms of material decay, and how deterioration has affected appearance. Conventional FTIR microscopy is of proven value in this field, but as samples typically need to be in the form of tiny powdered scrapings, precise information about location of materials within the microstructure of an object is lost. Analysis of samples prepared as cross-sections is useful since the distribution of materials within the layer structure reflects the working practices of the artist/maker and helps to differentiate between original and later materials, as well as deterioration products. Reflectance FTIR imaging has been used for this purpose but the spatial resolution is generally not sufficient. The higher spatial resolution achieved with ATR-FTIR imaging has transformed the appeal of FTIR techniques for this type of sample, and has the potential to become routine for the simultaneous characterization of organic and inorganic materials directly on cross-sections.

Congratulations to Sakoto for her winning poster!

Looking behind Dalí’s paintings

A new technique for assessing the condition of work of arts without taking samples from them has emerged from a research collaboration between conservators, curators and scientists.

Paintings undergo little mechanical stress hanging in a gallery, but are often transported between exhibitions. It is not easy to assess by eye whether they are strong enough to withstand handling and travel, and taking samples from them is not a desirable option.

The risk of paint degradation is increased if the painting’s canvas is in a poor condition, but so far more attention has been given to understanding paint layers than the supports behind them. Reductions in heritage funding make accurate scientific evidence crucial for optimising the environment and handling of paintings.

Advances in GC IV, Cheshire

Advances in GC IV
30th October 2013 (First Announcement)
LGC Ltd, The Heath Business Park, Runcorn, Cheshire

Joint meeting organised by The Chromatographic Society and the North West Region of the Analytical Division of the Royal Society of Chemistry.

After the success of the 2011 meeting we are pleased to announce another follow up meeting in the series.
GC is still technique of choice for analysing both volatile and semi volatile compounds, but as we move to more difficult matrices, more is being asked of the technique in terms of separation and limits of detection. The meeting sets out to both give an overview of current GC technologies and methodologies, information on newer detection/separation solutions and case studies from all the main user areas.
 
In parallel to the full meeting program will be an Instrument exhibition with representatives from all the major GC Instrument and Consumables Suppliers.

Keeping lipstick evidence in the bag

A new study shows it is possible to distinguish between types of lipstick on crime scene evidence without needing to remove it from the evidence bag, helping forensic scientists avoid sample contamination or destruction.

Lipstick marks can link someone to a crime scene. They can also establish physical contact between individuals for cases of violent crime.

Current forensic lipstick analysis relies on techniques such as microspectrophotometry, high performance liquid chromatography and energy dispersive x-ray analysis. These techniques, however, are not ideal for forensic investigations as they are either destructive or require a level of human opinion.
