Scientific Papers – The Dating Of Writing Inks Through 2-Phenoxyethanol Using Gas Chromatography – Mass Spectrometry, Advantages, Interpretation and Limitations

THE DATING OF WRITING INKS THROUGH 2-PHENOXYETHANOL USING GAS CHROMATOGRAPHY-MASS SPECTROMETRY, ADVANTAGES, INTERPRETATION, AND LIMITATIONS

Chromatography is the name give to analytical chemistry techniques that involve separating components of a mixture. There are two phases to chromatography methods: a mobile phase and a stationary phase. The mobile phase can be a gas or a liquid while the stationary phase can be a liquid or solid. During the separation, the mobile phase moves past the stationary phase. The separation of a mixture is based on a component’s interaction with each of the phases. Components that interact more with the mobile phase will move more quickly. Components that interact more with the stationary phase will be slowed.

From the Speckin Forensic FAQ’s – Can an examination be conducted of a signature or handwriting from only a photocopy?

Speckin Forensic Laboratories is an International forensic firm specializing in consulting with plaintiff and defense lawyers

Yes, but if it is possible to obtain the original it allows a more thorough examination of the document and the circumstances of its production. The possibility of a tracing of a machine copy transfer forgery cannot be ruled out.

Ink Dating Experts!

Ink Dating Experts Ink Dating analysis

Ink Dating is done in two primary forms. The first is the static approach, which determines when the ink being examined was manufactured. The second is the dynamic approach, this method is to determine when the writing occurred, or in simple terms, how long the ink has been on the paper.

The static approach is typically more useful as the difference between the date on the document and the present time increases. Several different tests exist in this form of ink dating. These methods include the comparison of the examined ink to a known library of standards, commonly called the library approach, the detection of chemical date tags placed in the ink purposefully by the manufacturer, commonly called the date tag method, and also the determination of the type of ink writing instrument used.

The determination of the type of writing instrument is probably the oldest method of ink dating. This primarily involves microscopic examinations and can also incorporate some basic chemical solubility testing. Some examinations can be performed on fountain pens to determine type of nib, type of ink and the first date of introduction of each of these.

Computer and Cell Phone Forensics

computer cell phone forensics experts

During the last five years, there have been exponential advances in technology and with the advent of the Internet; computers have become pervasive in everyday life. As a result, digital data in some form or another will be critical to most types of civil litigation and criminal proceedings.
The tools for conducting forensic examinations have also rapidly evolved, expediting the ability for securing evidentiary images, guaranteeing the integrity of digital evidence, and reducing the time and resources necessary for conducting a comprehensive examination of electronic media.
There is a rapidly emerging trend to use computer forensics for a broad range of civil litigation matters involving intellectual property rights, trademark infringement, misuse and theft of trade secrets, patent and copyright violations, as well as more traditional matters such as employment law litigation and criminal fraud.
