Or else it is a very useful tool to date contracts, settlements, wills or other documents.
Its use could have for example helped to determine the moment when the papers in the Bárcenas [corruption claims] case were written." To conduct the research work, the Department of Analytical Chemistry had the collaboration of the company Investigaciones Forenses Documentales LEYAS and Magdalena Ezcurra holder of a Ph D from the UPV/EHU.
The UPV/EHU's research team --comprising the professor of Analytical Chemistry Rosa María Alonso, Dr Itxaso San Román of the Farmartem group of the Department of Analytical Chemistry, and Dr Luis Bartolomé of the Central Analysis Service of Bizkaia (SGIker)-- has developed the Datink method that allows the period of time the ink may have remained on the paper to be determined and its age to be ascertained.
Forensics age dating ink
We use the most widely accepted chemical analysis technique known as gas chromatography/mass spectrometry (GC/MS) to help determine if a written entry was created in the past two years.
A new method that determines the age of a document in a less invasive way than other techniques and is also able to date documents up to five years old.
Likewise, the team that has developed this new method has managed to obtain results using minimal amounts taken from the document.
Unlike the large quantity of sample required by other traditional methods to age the compounds artificially and analyse them, the technique developed in the UPV/EHU labs allows the document to be dated using a single puncture and without altering the compounds. DATINK pilot study: An effective methodology for ballpoint pen ink dating in questioned documents, Archeologists have uncovered a large Bronze Age city not far from the town of Dohuk in northern Iraq.
This company also supplied the knowledge about the current problems in dating documents, real cases that had been subjected to legal examination.
Speckin Lawyers should be interested in the forensic examination of disputed records for three reasons: 1. Ink dating The dating of inks is done in three primary forms. Approximately one-third of all inks manufactured in North America contain a cumerin compound that is unique for its year of manufacture. Also, the first date of production can be established by determining the type and manufacture of the ink.
What is more, the new technique reduces the number of punctures needed to analyse the writing on a document to just one.
The problems Determining the age of a document to find out whether it is authentic is a task influenced by the type of paper on which it has been written, the pressure of the stroke -the amount of ink deposited when the writing was done- or even the technique used.
As Luis Bartolomé pointed out, "what is interesting about this method is that it can more accurately determine the age of the stroke produced by the ballpoint pen.
That is why it is very useful for documents that have been signed as it is possible to compare whether the body of the document, if it has been written by hand, is as old as the signature.
If an entry is dated in 1995, but the ink was not available until 2005 then the document could not have been created in 1995.
