GFSL Unveils Advanced SEM to Boost Forensic Investigations
The Guyana Forensic Science Laboratory (GFSL) has taken a monumental step forward in modernizing its forensic capabilities with the unveiling of a state-of-the-art Zeiss Sigma 360VP Scanning Electron Microscope (SEM).
The advanced equipment, launched on January 15, 2025, at the University of Guyana Complex in Turkeyen, is poised to revolutionize forensic investigations in the country by offering unprecedented precision in analyzing evidence at microscopic and nano levels.
Acquired under the 2024 national budget at a cost of €370,510 (approximately 86 million GYD), the SEM is set to enhance the GFSL’s ability to conduct detailed analyses of gunshot residue (GSR), trace evidence such as fibers and hair, and even paint particles.
These microscopic particles, which are often critical in criminal investigations, will now be examined with greater accuracy and speed, reducing delays that have previously hindered the timely resolution of cases.
Minister of Home Affairs, Robeson Benn, who delivered the feature address at the unveiling, emphasized the significance of this acquisition for both forensic science and broader scientific research in Guyana. “This acquisition represents a significant leap for science and research in Guyana, extending beyond the forensic science laboratory. It reflects our government’s commitment to equipping our scientists and researchers with cutting-edge technology that meets global standards,” Minister Benn stated.
He further noted that the SEM would improve the forensic examination of gunshot residue, an area that has seen delays in the past due to resource constraints.
“With this advanced instrument, we can now analyze the distribution, morphology, and chemistry of samples with unprecedented precision,” the Minister explained.
Permanent Secretary Andre Ally also highlighted the critical role the SEM would play in enhancing the operational efficiency of the GFSL, particularly in light of the increasing number of firearms seized by law enforcement agencies.
“The SEM will enable the GFSL to clear backlogs and deliver results more efficiently, strengthening our support for the justice system,” Ally said.
In addition to the SEM, the GFSL has been advancing its forensic offerings across several departments. The Biology Department now provides DNA profiling services, while the Documents Department uses advanced technologies to detect document forgeries and alterations.
Deputy Director of the GFSL, Ms. Charis Griffith, expressed pride in the laboratory’s continuous growth, noting that the GFSL has exceeded expectations by maintaining ISO 17025 international accreditation and continuously hiring qualified forensic professionals.
Representatives from Zeiss, the company that supplied the SEM, also highlighted the importance of the equipment in advancing scientific research. Juergen Frank, a Zeiss representative, shared that Zeiss invests 15% of its revenue into research and development, underscoring the company’s commitment to delivering groundbreaking solutions.
Carlos Peralta, another Zeiss representative, emphasized the SEM’s versatility, noting its broad applications across various scientific fields, stating, “Its potential is only limited by the imagination of its users.”
The acquisition of the SEM is part of a broader initiative to modernize the GFSL and includes other cutting-edge systems, such as the Orbitrap Exploris 120 Basic System (USD $353,344) for identifying and quantifying drugs and toxins, and the Agilent Technologies 8890/7000E GC MSMS System (USD $265,324) for analyzing chemical compounds and fire debris.
As part of these upgrades, five forensic experts are currently undergoing specialized training to ensure the laboratory is fully equipped to handle current and future forensic demands.
The unveiling of the SEM marks a significant investment in Guyana’s forensic science capabilities and reflects the government’s ongoing commitment to strengthening its criminal justice system through the use of advanced technology.
With these innovations, the GFSL is set to become a regional leader in forensic science, contributing to faster, more reliable results and strengthening the justice system’s ability to address complex crimes effectively.
