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.

When analysing the kinetics involved in its disappearance, the research group established a pattern that links the state of the ink with the time that has elapsed.
More accurate, less invasive After observing this natural evolution and once the base guideline had been established, the next challenge to be overcome was to check the viability of the method using spontaneously written documents whose exact age was known, such as diaries, laboratory logs and judicial evidence from judicial processes that had been closed.
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.
In fact, the dating of documents is a key area in the field of forensic science.
These are often very tricky questions to answer and frequently arise in judicial contexts.
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.
For example, a forensic document examiner can determine whether the stray toner particles (they are present on any laser-printed and photocopied documents but invisible to the naked eye) are below or above ballpoint pen ink writing (see Aginsky, V.
N., “Determining the Sequence of Non-Intersecting Media on Documents: Ballpoint Pen Ink and Laser Toner Entries,” , Vol.
Aware of these difficulties, the UPV/EHU team began to work on samples written for research purposes.
To do this, they used BIC® ballpoint pens, one of the most common makes and, therefore, the most widely used in documents subjected to legal examination.
In these cases, significant dating errors occur because the type of paper used and the mass/quantity of the ink deposited influence the analysis.Tags: Adult Dating, affair dating, sex dating
