Patiala (Punjab), June 8, 2025: In a significant development in the field of forensic science, researchers at Punjabi University, Patiala, have devised a scientific method to estimate the age of handwritten documents by analyzing the chemical elements of ink.
This innovation holds the potential to revolutionize the authentication of crucial documents like wills, contracts, and agreements.
The research, led by Dr. Vinayak Gupta under the guidance of Prof. Komal Saini at the Department of Forensic Science, has successfully used Gas Chromatography-Mass Spectrometry (GC-MS) to differentiate gel pen inks based on their chemical composition.
By identifying unique elemental signatures, the technique enables experts to determine the time of writing and detect cases of forgery, tampering, or alteration.
Prof. Komal Saini emphasized the importance of the method in verifying the authenticity and originality of documents frequently used in legal proceedings.
“This tool can assist investigative agencies and courts in making more informed decisions,” she said.
The study’s findings have already been published in leading international scientific journals and have been widely appreciated by experts in forensic science and law.
Dr. Vinayak Gupta highlighted that the reliability of the method was validated through rigorous large-scale statistical analyses, confirming its practical use in real-world forensic investigations.
“This technique offers a scientific way to resolve complex issues of document manipulation that often challenge the legal system,” he noted.
Lauding the achievement, Vice Chancellor Dr. Jagdeep Singh called the development a matter of great pride for Punjabi University and particularly its Forensic Science Department.
“Such innovative research enhances the university’s standing and can significantly impact criminal investigations, civil litigation, and the broader field of justice delivery,” he said.
This pioneering work is expected to be a game-changer in forensic document examination, offering new tools for law enforcement and judicial authorities worldwide.
